It is unclear how such massive black holes (BHs) formed so early. One possible explanation is that these SMBHs were seeded by \"heavy\" direct collapse black holes (DCBHs) with masses of MBH ≈ 105 M⊙, but observations have not yet confirmed or refuted this scenario. In this Letter, we utilize a cosmological N-body simulation to demonstrate that before they grow roughly an order of magnitude in mass, DCBHs will have BH mass to halo mass ratios that are much higher than expected for BH remnants of Population III (Pop III) stars that have grown to the same mass (∼106 M⊙). We also show that when Tvir ≈ 104 K halos (the potential sites of DCBH formation) merge with much larger nearby halos (Mh > 1010 M⊙), they almost always orbit their larger host halos with a separation of a few kpc, which is sufficient to be spatially resolved with future X-ray and infrared telescopes. Thus, we propose that a future X-ray mission such as Lynx, combined with infrared observations, will be able to distinguish high-redshift DCBHs from smaller BH seeds due to the unusually high BH mass to stellar mass ratios of the faintest observed quasars, with inferred BH masses below ∼106 M⊙.","lang":"eng"}],"publication":"The Astrophysical Journal Letters"},{"volume":863,"year":"2018","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","status":"public","author":[{"full_name":"Inayoshi, Kohei","last_name":"Inayoshi","first_name":"Kohei"},{"last_name":"Ichikawa","full_name":"Ichikawa, Kohei","first_name":"Kohei"},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman","full_name":"Haiman, Zoltán","first_name":"Zoltán"}],"article_number":"L36","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.1805.05334"}],"date_updated":"2024-09-24T11:47:28Z","oa_version":"Preprint","issue":"2","arxiv":1,"external_id":{"arxiv":["1805.05334"]},"date_created":"2024-09-06T07:18:03Z","publisher":"American Astronomical Society","article_processing_charge":"No","title":"Gravitational waves from supermassive black hole binaries in ultraluminous infrared galaxies","publication_identifier":{"issn":["2041-8205","2041-8213"]},"citation":{"short":"K.

ULIRGs are likely associated with gas-rich galaxy mergers containing SMBHs that possibly occur at most once in the life of galaxies, unlike multiple dry mergers at low redshift. Adopting a well-established sample of ULIRGs, we study the properties of the GWB due to coalescing binary SMBHs in these galaxies.

Our model follows dark matter haloes from cosmological N-body simulations, utilizing their individual merger histories and three-dimensional positions, and applies physically motivated prescriptions for star formation and feedback from Lyman–Werner (LW) radiation, hydrogen ionizing radiation, and external metal enrichment due to supernovae winds. This method is intended to complement analytic studies, which do not include clustering or individual merger histories, and hydrodynamical cosmological simulations, which include detailed physics, but are computationally expensive and have limited dynamic range. Utilizing this technique, we compute the cumulative Pop III and metal-enriched star formation rate density (SFRD) as a function of redshift at z ≥ 20. We find that varying the model parameters leads to significant qualitative changes in the global star formation history. The Pop III star formation efficiency and the delay time between Pop III and subsequent metal-enriched star formation are found to have the largest impact. The effect of clustering (i.e. including the three-dimensional positions of individual haloes) on various feedback mechanisms is also investigated. The impact of clustering on LW and ionization feedback is found to be relatively mild in our fiducial model, but can be larger if external metal enrichment can promote metal-enriched star formation over large distances."}],"publication":"Monthly Notices of the Royal Astronomical Society","quality_controlled":"1","volume":475,"author":[{"last_name":"Visbal","full_name":"Visbal, Eli","first_name":"Eli"},{"first_name":"Zoltán","full_name":"Haiman, Zoltán","last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"first_name":"Greg L","full_name":"Bryan, Greg L","last_name":"Bryan"}],"status":"public","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","year":"2018","page":"5246-5256","date_updated":"2024-09-24T14:23:23Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/sty142"}],"language":[{"iso":"eng"}],"issue":"4","oa_version":"Published Version","publisher":"Oxford University Press","date_created":"2024-09-06T07:33:13Z","title":"Self-consistent semi-analytic models of the first stars","article_processing_charge":"No"},{"title":"Non-Gaussian information from weak lensing data via deep learning","article_processing_charge":"No","publisher":"American Physical Society","date_created":"2024-09-06T07:39:50Z","external_id":{"arxiv":["1802.01212"]},"arxiv":1,"issue":"10","oa_version":"Preprint","date_updated":"2024-09-25T07:28:42Z","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.1802.01212","open_access":"1"}],"language":[{"iso":"eng"}],"article_number":"103515","author":[{"last_name":"Gupta","full_name":"Gupta, Arushi","first_name":"Arushi"},{"first_name":"José Manuel Zorrilla","full_name":"Matilla, José Manuel Zorrilla","last_name":"Matilla"},{"last_name":"Hsu","full_name":"Hsu, Daniel","first_name":"Daniel"},{"first_name":"Zoltán","full_name":"Haiman, Zoltán","last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"}],"status":"public","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","year":"2018","volume":97,"quality_controlled":"1","abstract":[{"text":"Weak lensing maps contain information beyond two-point statistics on small scales.

When the gas angular momentum is low enough to form a rotationally supported disk within the Bondi radius (RB), we find a global steady accretion solution. The solution consists of a rotational equilibrium distribution at r∼RB, where the density follows ρ∝(1+RB/r)^3/2, surrounding a geometrically thick and optically thin accretion disk at the centrifugal radius, where thermal energy generated by viscosity is transported via strong convection. Physical properties of the inner solution agree with those expected in convection-dominated accretion flows (CDAF; ρ∝r^−1/2). In the inner CDAF solution, the gas inflow rate decreases towards the center due to convection (M˙∝r), and the net accretion rate (including both inflows and outflows) is strongly suppressed by several orders of magnitude from the Bondi accretion rate M˙B The net accretion rate depends on the viscous strength, following M˙/M˙B∝(α/0.01)^0.6. This solution holds for low accretion rates of M˙B/M˙Edd<10^−3 having minimal radiation cooling, where M˙Edd is the Eddington rate. In a hot plasma at the bottom (r<10^−3 RB), thermal conduction would dominate the convective energy flux. Since suppression of the accretion by convection ceases, the final BH feeding rate is found to be M˙/M˙B∼10^−3−10^−2. This rate is as low as M˙/M˙Edd∼10^−7−10^−6 inferred for SgrA∗ and the nuclear BHs in M31 and M87, and can explain the low luminosities in these sources, without invoking any feedback mechanism.","lang":"eng"}],"publication":"Monthly Notices of the Royal Astronomical Society","quality_controlled":"1"},{"article_processing_charge":"No","title":"Testing the binary hypothesis: Pulsar timing constraints on supermassive black hole binary candidates","date_created":"2024-09-06T08:06:14Z","publisher":"American Astronomical Society","issue":"1","oa_version":"Published Version","main_file_link":[{"url":"https://doi.org/10.3847/1538-4357/aaad0f","open_access":"1"}],"language":[{"iso":"eng"}],"date_updated":"2024-09-25T09:02:27Z","article_number":"42","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","year":"2018","author":[{"last_name":"Sesana","full_name":"Sesana, Alberto","first_name":"Alberto"},{"first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","last_name":"Haiman"},{"last_name":"Kocsis","full_name":"Kocsis, Bence","first_name":"Bence"},{"full_name":"Kelley, Luke Zoltan","last_name":"Kelley","first_name":"Luke Zoltan"}],"status":"public","volume":856,"quality_controlled":"1","publication":"The Astrophysical Journal","abstract":[{"lang":"eng","text":"The advent of time domain astronomy is revolutionizing our understanding of the universe. Programs such as the Catalina Real-time Transient Survey (CRTS) or the Palomar Transient Factory (PTF) surveyed millions of objects for several years, allowing variability studies on large statistical samples. The inspection of ≈250 k quasars in CRTS resulted in a catalog of 111 potentially periodic sources, put forward as supermassive black hole binary (SMBHB) candidates. A similar investigation on PTF data yielded 33 candidates from a sample of ≈35 k quasars. Working under the SMBHB hypothesis, we compute the implied SMBHB merger rate and we use it to construct the expected gravitational wave background (GWB) at nano-Hz frequencies, probed by pulsar timing arrays (PTAs). After correcting for incompleteness and assuming virial mass estimates, we find that the GWB implied by the CRTS sample exceeds the current most stringent PTA upper limits by almost an order of magnitude. After further correcting for the implicit bias in virial mass measurements, the implied GWB drops significantly but is still in tension with the most stringent PTA upper limits. Similar results hold for the PTF sample. Bayesian model selection shows that the null hypothesis (whereby the candidates are false positives) is preferred over the binary hypothesis at about 2.3σ and 3.6σ for the CRTS and PTF samples respectively. Although not decisive, our analysis highlights the potential of PTAs as astrophysical probes of individual SMBHB candidates and indicates that the CRTS and PTF samples are likely contaminated by several false positives."}],"month":"03","oa":1,"_id":"17680","extern":"1","type":"journal_article","publication_status":"published","fulldoi":"https://doi.org/10.3847/1538-4357/aaad0f","intvolume":"       856","day":"22","article_type":"original","date_published":"2018-03-22T00:00:00Z","publication_identifier":{"issn":["0004-637X","1538-4357"]},"citation":{"apa":"Sesana, A., Haiman, Z., Kocsis, B., &#38; Kelley, L.

Since the streaming motion prevents gas collapse into DM halos and delays prior star formation episodes, the gas remains metal-free until the halo virial temperatures ≳2×10^4 K. The minimum cooling mass of DM halos is boosted by a factor of ∼10−30 because frequent major mergers of halos further inhibit gas collapse. We use Monte Carlo merger trees to simulate the DM assembly history under a streaming velocity of twice the root-mean-square value, and estimate the number density of massive DM halos containing pristine gas as ≃10^−4 cMpc^−3. When the gas infall begins, efficient Lyα cooling drives cold streams penetrating inside the halo and feeding a central galactic disk. When one stream collides with the disk, strong shock forms a dense and hot gas cloud, where the gas never forms H2 molecules due to effective collisional dissociation. As a result, a massive gas cloud forms by gravitational instability and collapses directly into a massive black hole (BH) with M∙∼10^5 M⊙. Almost simultaneously, a galaxy with M⋆,tot∼10^6 M⊙ composed of Population III stars forms in the nuclear region. If the typical stellar mass is as high as ∼100 M⊙, the galaxy could be detected with the James Webb Space Telescope even at z≳15. These massive seed BHs would be fed by continuous gas accretion from the host galaxy, and grow to be bright quasars observed at z≳6.","lang":"eng"}],"publication":"Monthly Notices of the Royal Astronomical Society","quality_controlled":"1","extern":"1","_id":"17687","oa":1,"month":"06"},{"volume":476,"year":"2018","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","status":"public","author":[{"last_name":"Charisi","full_name":"Charisi, Maria","first_name":"Maria"},{"first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","last_name":"Haiman"},{"full_name":"Schiminovich, David","last_name":"Schiminovich","first_name":"David"},{"first_name":"Daniel J","full_name":"D'Orazio, Daniel J","last_name":"D'Orazio"}],"page":"4617-4628","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.1093/mnras/sty516","open_access":"1"}],"date_updated":"2024-09-25T09:56:16Z","oa_version":"Published Version","issue":"4","date_created":"2024-09-06T08:38:11Z","publisher":"Oxford University Press","article_processing_charge":"No","title":"Testing the relativistic Doppler boost hypothesis for supermassive black hole binary candidates","publication_identifier":{"issn":["0035-8711","1365-2966"]},"citation":{"ama":"Charisi M, Haiman Z, Schiminovich D, D’Orazio DJ.

Recently, a large sample of sub-parsec SMBHB candidates was identified as bright periodically variable quasars in optical surveys. If the observed periodicity corresponds to the redshifted binary orbital period, the inferred orbital velocities are relativistic (v/c ≈ 0.1). The optical and ultraviolet (UV) luminosities are expected to arise from gas bound to the individual BHs, and would be modulated by the relativistic Doppler effect. The optical and UV light curves should vary in tandem with relative amplitudes which depend on the respective spectral slopes. We constructed a control sample of 42 quasars with aperiodic variability, to test whether this Doppler colour signature can be distinguished from intrinsic chromatic variability. We found that the Doppler signature can arise by chance in ∼20 per cent (∼37 per cent) of quasars in the nUV (fUV) band. These probabilities reflect the limited quality of the control sample and represent upper limits on how frequently quasars mimic the Doppler brightness+colour variations. We performed separate tests on the periodic quasar candidates, and found that for the majority, the Doppler boost hypothesis requires an unusually steep UV spectrum or an unexpectedly large BH mass and orbital velocity. We conclude that at most approximately one-third of these periodic candidates can harbor Doppler-modulated SMBHBs.","lang":"eng"}],"quality_controlled":"1"},{"citation":{"apa":"Liu, J., Bird, S., Matilla, J.

Since the level of suppression depends on the sum of the masses of the three active neutrino species, the evolution of large-scale structure is a promising tool to constrain the total mass of neutrinos and possibly shed light on the mass hierarchy. In this work, we investigate these effects via a large suite of N-body simulations that include massive neutrinos using an analytic linear-response approximation: the Cosmological Massive Neutrino Simulations (MassiveNuS). The simulations include the effects of radiation on the background expansion, as well as the clustering of neutrinos in response to the nonlinear dark matter evolution. We allow three cosmological parameters to vary: the neutrino mass sum M_nu in the range of 0-0.6 eV, the total matter density Omega_m, and the primordial power spectrum amplitude A_s. The rms density fluctuation in spheres of 8 comoving Mpc/h (sigma_8) is a derived parameter as a result. Our data products include N-body snapshots, halo catalogues, merger trees, ray- traced galaxy lensing convergence maps for four source redshift planes between z_s=1-2.5, and ray-traced cosmic microwave background lensing convergence maps.

We determine the relative conductance of the (bi)cyclic silicon structures by using the common length dependence of the four series rather than comparing the conductance at a single length. In contrast with the cyclic π-conjugated molecules, the conductance of σ-conjugated (bi)cyclic silanes is dominated by a single path through the molecule and is controlled by the dihedral angles along this path.

Herein, we perform scanning tunneling microscope based break-junction measurements on a series of three cyanine dyes of increasing length. We demonstrate, at the single molecule level, that these short chain polymethine systems exhibit a substantially smaller decay in conductance with length (attenuation factor β = 0.04 Å–1) compared to traditional polyenes (β ≈ 0.2 Å–1). Furthermore, we show that by changing solvent we are able to shift the β value, demonstrating a remarkable negative β value, with conductance increasing with molecular length. First principle calculations provide support for the experimentally observed near-uniform length dependent conductance and further suggest that the variations in β with solvent are due to solvent-induced changes in the alignment of the frontier molecular orbitals relative to the Fermi energy of the leads. A simplified Hückel model suggests that the smaller decay in conductance correlates with the smaller degree of bond order alternation present in polymethine compounds compared to polyenes. These findings may enable the design of molecular wires without a length-dependent decay for efficient electron transport at the nanoscale.","lang":"eng"}],"publication":"Nano Letters","quality_controlled":"1"},{"date_updated":"2024-12-11T08:42:51Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1021/jacs.8b05184"}],"language":[{"iso":"eng"}],"page":"8944-8949","author":[{"first_name":"Evan A.","last_name":"Doud","full_name":"Doud, Evan A."},{"full_name":"Inkpen, Michael S.","last_name":"Inkpen","first_name":"Michael S."},{"full_name":"Lovat, Giacomo","last_name":"Lovat","first_name":"Giacomo"},{"first_name":"Enrique","full_name":"Montes, Enrique","last_name":"Montes"},{"last_name":"Paley","full_name":"Paley, Daniel W.","first_name":"Daniel W."},{"full_name":"Steigerwald, Michael L.","last_name":"Steigerwald","first_name":"Michael L."},{"last_name":"Vázquez","full_name":"Vázquez, Héctor","first_name":"Héctor"},{"first_name":"Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","last_name":"Venkataraman","full_name":"Venkataraman, Latha","orcid":"0000-0002-6957-6089"},{"first_name":"Xavier","last_name":"Roy","full_name":"Roy, Xavier"}],"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2018","volume":140,"title":"In situ formation of N-heterocyclic carbene-bound single-molecule junctions","article_processing_charge":"No","publisher":"American Chemical Society","pmid":1,"OA_place":"publisher","date_created":"2024-09-09T08:14:38Z","external_id":{"pmid":["29969027"]},"issue":"28","oa_version":"Published Version","intvolume":"       140","day":"03","type":"journal_article","publication_status":"published","fulldoi":"https://doi.org/10.1021/jacs.8b05184","article_type":"original","date_published":"2018-07-03T00:00:00Z","scopus_import":"1","doi":"10.1021/jacs.8b05184","citation":{"ieee":"E.

The rich chemistry and strong σ-donating ability of NHCs offer unique prospects for applications in nanoelectronics, sensing, and electrochemistry. Although stable in SAMs, free carbenes are notoriously reactive, making their electronic characterization challenging. Here we report the first investigation of electron transport across single NHC-bound molecules using the scanning tunneling microscope-based break junction (STM-BJ) technique. We develop a series of air-stable metal NHC complexes that can be electrochemically reduced in situ to form NHC–electrode contacts, enabling reliable single-molecule conductance measurements of NHCs under ambient conditions. Using this approach, we show that the conductance of an NHC depends on the identity of the single metal atom to which it is coordinated in the junction. Our observations are supported by density functional theory (DFT) calculations, which also firmly establish the contributions of the NHC linker to the junction transport characteristics. Our work demonstrates a powerful method to probe electron transfer across NHC–electrode interfaces; more generally, it opens the door to the exploitation of surface-bound NHCs in constructing novel, functionalized electrodes and/or nanoelectronic devices.","lang":"eng"}],"publication":"Journal of the American Chemical Society","OA_type":"free access","extern":"1","_id":"17930","month":"07","oa":1},{"doi":"10.1038/s41586-018-0197-9","publication_identifier":{"issn":["0028-0836"],"eissn":["1476-4687"]},"citation":{"ama":"Garner MH, Li H, Chen Y, et al.

It was recently demonstrated3,4,5 that coherent tunnelling through a molecular junction can also be suppressed by destructive quantum interference6, a mechanism that is not length-dependent. For the carbon-based molecules studied previously, cancelling all transmission channels would involve the suppression of contributions to the current from both the π-orbital and σ-orbital systems. Previous reports of destructive interference have demonstrated a decrease in transmission only through the π-channel. Here we report a saturated silicon-based molecule with a functionalized bicyclo[2.2.2]octasilane moiety that exhibits destructive quantum interference in its σ-system. Although molecular silicon typically forms conducting wires7, we use a combination of conductance measurements and ab initio calculations to show that destructive σ-interference, achieved here by locking the silicon–silicon bonds into eclipsed conformations within a bicyclic molecular framework, can yield extremely insulating molecules less than a nanometre in length. Our molecules also exhibit an unusually high thermopower (0.97 millivolts per kelvin), which is a further experimental signature of the suppression of all tunnelling paths by destructive interference: calculations indicate that the central bicyclo[2.2.2]octasilane unit is rendered less conductive than the empty space it occupies. The molecular design presented here provides a proof-of-concept for a quantum-interference-based approach to single-molecule insulators.","lang":"eng"}],"quality_controlled":"1","volume":558,"year":"2018","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","author":[{"full_name":"Garner, Marc H.","last_name":"Garner","first_name":"Marc H."},{"first_name":"Haixing","full_name":"Li, Haixing","last_name":"Li"},{"first_name":"Yan","last_name":"Chen","full_name":"Chen, Yan"},{"first_name":"Timothy A.","last_name":"Su","full_name":"Su, Timothy A."},{"last_name":"Shangguan","full_name":"Shangguan, Zhichun","first_name":"Zhichun"},{"first_name":"Daniel W.","last_name":"Paley","full_name":"Paley, Daniel W."},{"last_name":"Liu","full_name":"Liu, Taifeng","first_name":"Taifeng"},{"last_name":"Ng","full_name":"Ng, Fay","first_name":"Fay"},{"first_name":"Hexing","last_name":"Li","full_name":"Li, Hexing"},{"full_name":"Xiao, Shengxiong","last_name":"Xiao","first_name":"Shengxiong"},{"first_name":"Colin","last_name":"Nuckolls","full_name":"Nuckolls, Colin"},{"orcid":"0000-0002-6957-6089","first_name":"Latha","full_name":"Venkataraman, Latha","last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf"},{"first_name":"Gemma C.","full_name":"Solomon, Gemma C.","last_name":"Solomon"}],"page":"415-419","language":[{"iso":"eng"}],"date_updated":"2024-12-11T08:51:55Z","oa_version":"None","issue":"7710","external_id":{"pmid":["29875407"]},"date_created":"2024-09-09T08:17:04Z","pmid":1,"publisher":"Springer Nature","article_processing_charge":"No","title":"Comprehensive suppression of single-molecule conductance using destructive σ-interference"},{"language":[{"iso":"eng"}],"date_updated":"2024-12-11T08:56:09Z","page":"8014-8022","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2018","author":[{"full_name":"Ravikumar, Abhilash","last_name":"Ravikumar","first_name":"Abhilash"},{"last_name":"Kladnik","full_name":"Kladnik, Gregor","first_name":"Gregor"},{"first_name":"Moritz","last_name":"Müller","full_name":"Müller, Moritz"},{"last_name":"Cossaro","full_name":"Cossaro, Albano","first_name":"Albano"},{"full_name":"Bavdek, Gregor","last_name":"Bavdek","first_name":"Gregor"},{"full_name":"Patera, Laerte L.","last_name":"Patera","first_name":"Laerte L."},{"first_name":"Daniel","full_name":"Sánchez-Portal, Daniel","last_name":"Sánchez-Portal"},{"id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","full_name":"Venkataraman, Latha","last_name":"Venkataraman","first_name":"Latha","orcid":"0000-0002-6957-6089"},{"first_name":"Alberto","last_name":"Morgante","full_name":"Morgante, Alberto"},{"last_name":"Brivio","full_name":"Brivio, Gian Paolo","first_name":"Gian Paolo"},{"last_name":"Cvetko","full_name":"Cvetko, Dean","first_name":"Dean"},{"first_name":"Guido","last_name":"Fratesi","full_name":"Fratesi, Guido"}],"status":"public","volume":10,"article_processing_charge":"No","title":"Tuning ultrafast electron injection dynamics at organic-graphene/metal interfaces","pmid":1,"date_created":"2024-09-09T08:19:10Z","publisher":"Royal Society of Chemistry","external_id":{"pmid":["29667672"]},"issue":"17","oa_version":"None","type":"journal_article","fulldoi":"https://doi.org/10.1039/c7nr08737c","publication_status":"published","intvolume":"        10","day":"26","article_type":"original","date_published":"2018-03-26T00:00:00Z","citation":{"ieee":"A.

We show that the ultrafast injection of electrons from the substrate to the molecule is ∼4 times slower on weakly coupled bilayer graphene than on epitaxial graphene. Through our experiments and calculations, we can attribute this to a difference in the density of states close to the Fermi level between graphene and bilayer graphene. We therefore show how graphene coupling with the substrate influences charge transfer dynamics between organic molecules and graphene interfaces.","lang":"eng"}],"OA_type":"closed access","month":"03","extern":"1","_id":"17932"},{"month":"01","oa":1,"_id":"17933","extern":"1","OA_type":"hybrid","publication":"Nanoscale","abstract":[{"text":"Break-junction measurements are typically aimed at characterizing electronic properties of single molecules bound between two metal electrodes.

We compare our results with alkanes terminated asymmetrically with an amine group on one end and a carboxyl group on the other to show that peptide bonds decrease the conductance of an otherwise saturated carbon chain. Using a newly developed first-principles approach, we attribute the decrease in conductance to charge localization at the peptide bond, which reduces the energy of the frontier orbitals relative to the Fermi energy and the electronic coupling to the leads, lowering the tunneling probability. Crucially, this manifests as an increase in conductance decay of peptide backbones with increasing length when compared with alkanes.","lang":"eng"}],"quality_controlled":"1","month":"01","oa":1,"_id":"17934","extern":"1","OA_type":"green"},{"date_created":"2018-12-11T11:44:11Z","publisher":"Charles Babbage Research Centre","article_processing_charge":"No","title":"Superconcentrators of density 25.3","oa_version":"Preprint","issue":"10","arxiv":1,"external_id":{"isi":["000446809500022"],"arxiv":["1405.7828"]},"page":"269 - 304","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1405.7828"}],"date_updated":"2023-09-19T14:46:18Z","volume":141,"isi":1,"year":"2018","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","status":"public","author":[{"id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","full_name":"Kolmogorov, Vladimir","last_name":"Kolmogorov","first_name":"Vladimir"},{"id":"3CB3BC06-F248-11E8-B48F-1D18A9856A87","last_name":"Rolinek","full_name":"Rolinek, Michal","first_name":"Michal"}],"publist_id":"8037","publication":"Ars Combinatoria","abstract":[{"lang":"eng","text":"An N-superconcentrator is a directed, acyclic graph with N input nodes and N output nodes such that every subset of the inputs and every subset of the outputs of same cardinality can be connected by node-disjoint paths.

The UEG is defined differently from Jellium, which has a positive constant background but no constraint on the density. We prove that the UEG arises in Density Functional Theory in the limit of a slowly varying density, minimizing the indirect Coulomb energy. We also construct the quantum UEG and compare it to the classical UEG at low density.","lang":"eng"}],"publist_id":"7741","publication":"Journal de l'Ecole Polytechnique - Mathematiques","_id":"180","oa":1,"month":"07"}]
