This has recently been demonstrated using N-body simulations which neglect baryonic effects. Here we employ ray-tracing N-body simulations in which we manually steepen the density profile of each dark matter halo, mimicking the cooling and concentration of baryons into dark matter potential wells. We find, in agreement with previous works, that this causes a significant increase in the amplitude of the WL power spectrum on small scales (spherical harmonic index l>1,000). We then study the impact of the halo concentration increase on the peak counts, and find the following. (i) Low peaks (with convergence 0.02 < kappa_peak < 0.08), remain nearly unaffected. These peaks are created by a constellation of several halos with low masses (10^12-10^13 M_sun) and large angular offsets from the peak center (> 0.5 R_vir); as a result, they are insensitive to the central halo density profiles. These peaks contain most of the cosmological information, and thus provide an unusually sensitive and unbiased probe. (ii) The number of high peaks (with convergence kappa_peak > 0.08) is increased. However, when the baryon effects are neglected in cosmological parameter estimation, then the high peaks lead to a modest bias, comparable to that from the power spectrum on relatively large-scales (l<2000), and much smaller than the bias from the power spectrum on smaller scales (l>2,000). (iii) In the 3D parameter space (sigma_8, Omega_m, w), the biases from the high peaks and the power spectra are in different directions. This suggests the possibility of \"self-calibration\": the combination of peak counts and power spectrum can simultaneously constrain baryonic physics and cosmological parameters."}],"publisher":"American Physical Society","_id":"17677","date_updated":"2024-09-25T08:50:09Z","external_id":{"arxiv":["1210.0608"]},"title":"Baryon impact on weak lensing peaks and power spectrum: Low-bias statistics and self-calibration in future surveys"},{"article_processing_charge":"No","doi":"10.1093/mnras/stt567","citation":{"ama":"McKernan B, Ford KES, Kocsis B, Haiman Z.

A gap-opening secondary close to the primary will leave an imprint in the broad component of the Fe Kα emission line, which varies in a unique and predictable manner. If the gap persists into the innermost disc, the effect consists of a pair of dips in the broad line which ripple blue-ward and red-ward from the line centroid energy, respectively, as the gap moves closer to the primary. This ripple effect could be unambiguously detectable and allow an electromagnetic monitoring of massive black hole mergers as they occur. As the mass ratio of the secondary to primary black hole increases to q ≳ 0.01, we expect the gap to widen, possibly clearing a central cavity in the inner disc, which shows up in the broad Fe Kα line component. If the secondary stalls at ≥ 102rg in its in-migration, due to low corotating gas mass, a detectable ripple effect occurs in the broad line component on the disc viscous time-scale as the inner disc drains and the outer disc is dammed. If the secondary maintains an accretion disc within a central cavity, due to dam bursting or leakage, a periodic ‘see-saw’ oscillation effect is exhibited in the observed line profile. Here, we demonstrate the range of ripple effect signatures potentially detectable with Astro-H and IXO/Athena, and oscillation effects potentially detectable with XMM–Newton or LOFT for a wide variety of merger and disc conditions, including gap width (or cavity size), disc inclination angle and emissivity profile, damming of the accretion flow by the secondary, and a minidisc around the satellite black hole. A systematic study of ripple effects would require a telescope effective area substantially larger than that planned for IXO/Athena. Future mission planning should take this into account. Observations of the ripple effect and periodic oscillations can be used to provide an early warning of gravitational radiation emission from the AGN. Once gravitational waves consistent with massive black hole mergers are detected, an archival search for the Fe Kα ripple effect or periodic oscillations will help in localizing their origin.","lang":"eng"}],"publisher":"Oxford University Press","_id":"17683","date_updated":"2024-09-25T09:13:00Z","title":"Ripple effects and oscillations in the broad Fe Kα line as a probe of massive black hole mergers","main_file_link":[{"url":"https://doi.org/10.1093/mnras/stt567","open_access":"1"}],"oa_version":"Published Version","language":[{"iso":"eng"}],"month":"05","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","scopus_import":"1","publication_status":"published","fulldoi":"https://doi.org/10.1093/mnras/stt567","publication":"Monthly Notices of the Royal Astronomical Society","intvolume":" 432","extern":"1","status":"public","year":"2013","issue":"2","type":"journal_article","date_created":"2024-09-06T08:18:32Z","oa":1,"date_published":"2013-05-02T00:00:00Z","page":"1468-1482","author":[{"last_name":"McKernan","first_name":"B.","full_name":"McKernan, B."},{"full_name":"Ford, K.

We assume primordial gas and H2-cooling and prior star-formation have been suppressed. We analysed 19 haloes (gas and DM) at a resolution of ~10 (proper) pc, selected from a total volume of ~2E3 (comoving) Mpc3. This is the largest statistical hydro-sim. study of ACHs at z>10 to date. We examine the morphology, angular momentum (AM), thermodynamic, and turbulence of these haloes, in order to assess the prevalence of disks and supermassive black holes (SMBHs). We find no correlation between either the magnitude or the direction of the AM of the gas and its parent DM halo. Only 3 haloes form rotationally supported cores. Two of the most massive haloes form massive, compact overdense blobs. These blobs have an accretion rate ~0.5 Msun/yr (at a distance of 100 pc), and are possible sites of SMBH formation. Our results suggest that the degree of rotational support and the fate of the gas in a halo is determined by its large-scale environment and merger history. In particular, the two haloes forming blobs are located at knots of the cosmic web, cooled early on, and experienced many mergers. The gas in these haloes is lumpy and highly turbulent, with Mach N. >~ 5. In contrast, the haloes forming rotationally supported cores are relatively more isolated, located midway along filaments, cooled more recently, and underwent fewer mergers. Thus, the gas in these haloes is less lumpy and less turbulent (Mach <~ 4), and could retain most of its AM. The remaining 14 haloes have intermediate properties. If verified in a larger sample of haloes and with additional physics, our results will have implications for observations of the highest-redshift galaxies and quasars with JWST."}],"publication_identifier":{"issn":["1365-2966","0035-8711"]},"article_processing_charge":"No","title":"Gas infall into atomic cooling haloes: On the formation of protogalactic discs and supermassive black holes at z > 10","_id":"17684","publisher":"Oxford University Press","date_updated":"2024-09-25T09:15:36Z","scopus_import":"1","month":"10","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","language":[{"iso":"eng"}],"oa_version":"Published Version","main_file_link":[{"url":"https://doi.org/10.1093/mnras/stt1730","open_access":"1"}],"publication":"Monthly Notices of the Royal Astronomical Society","publication_status":"published","fulldoi":"https://doi.org/10.1093/mnras/stt1730","oa":1,"date_published":"2013-10-08T00:00:00Z","date_created":"2024-09-06T08:19:41Z","issue":"3","type":"journal_article","intvolume":" 436","status":"public","extern":"1","year":"2013","day":"08","author":[{"first_name":"Joaquin","full_name":"Prieto, Joaquin","last_name":"Prieto"},{"last_name":"Jimenez","full_name":"Jimenez, Raul","first_name":"Raul"},{"full_name":"Haiman, Zoltán","first_name":"Zoltán","last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"}],"page":"2301-2325","volume":436,"quality_controlled":"1","article_type":"original"},{"external_id":{"arxiv":["1309.4460"]},"date_updated":"2024-09-25T11:35:11Z","_id":"17704","publisher":"American Physical Society","title":"Cosmology with Minkowski functionals and moments of the weak lensing convergence field","abstract":[{"text":"We compare the efficiency of moments and Minkowski functionals (MFs) in constraining the subset of cosmological parameters (Omega_m,w,sigma_8) using simulated weak lensing convergence maps.

We show that this perturbation series breaks down on smoothing scales below 5', while it shows a good degree of convergence on larger scales (15'). Most of the cosmological distinguishing power is lost when the maps are smoothed on these larger scales. We also show that, on scales comparable to 1', where the perturbation series does not converge, cosmological constraints obtained from the MFs are approximately 1.5-2 times better than the ones obtained from the first few moments of the convergence distribution --- provided that the latter include spatial information, either from moments of gradients, or by combining multiple smoothing scales. Including either a set of these moments or the MFs can significantly tighten constraints on cosmological parameters, compared to the conventional method of using the power spectrum alone.","lang":"eng"}],"publication_identifier":{"issn":["1550-7998","1550-2368"]},"doi":"10.1103/physrevd.88.123002","citation":{"mla":"Petri, Andrea, et al. “Cosmology with Minkowski Functionals and Moments of the Weak Lensing Convergence Field.” Physical Review D, vol. 88, no. 12, 123002, American Physical Society, 2013, doi:10.1103/physrevd.88.123002.","apa":"Petri, A., Haiman, Z., Hui, L., May, M., & Kratochvil, J.

The geometric phase is determined only by the shape of this path and is, in its simplest form, a real number. However, if the system has degenerate energy levels, then matrix-valued geometric state transformations, known as non-Abelian holonomies-the effect of which depends on the order of two consecutive paths-can be obtained. They are important, for example, for the creation of synthetic gauge fields in cold atomic gases or the description of non-Abelian anyon statistics. Moreover, there are proposals to exploit non-Abelian holonomic gates for the purposes of noise-resilient quantum computation. In contrast to Abelian geometric operations, non-Abelian ones have been observed only in nuclear quadrupole resonance experiments with a large number of spins, and without full characterization of the geometric process and its non-commutative nature. Here we realize non-Abelian non-adiabatic holonomic quantum operations on a single, superconducting, artificial three-level atom by applying a well-controlled, two-tone microwave drive. Using quantum process tomography, we determine fidelities of the resulting non-commuting gates that exceed 95 per cent. We show that two different quantum gates, originating from two distinct paths in Hilbert space, yield non-equivalent transformations when applied in different orders. This provides evidence for the non-Abelian character of the implemented holonomic quantum operations. In combination with a non-trivial two-quantum-bit gate, our method suggests a way to universal holonomic quantum computing."}],"publist_id":"5329","quality_controlled":0,"volume":496,"page":"482 - 485","author":[{"last_name":"Abdumalikov","first_name":"Abdufarrukh","full_name":"Abdumalikov, Abdufarrukh A"},{"first_name":"Johannes M","full_name":"Johannes Fink","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","last_name":"Fink","orcid":"0000-0001-8112-028X"},{"first_name":"K","full_name":"Juliusson, K","last_name":"Juliusson"},{"first_name":"M","full_name":"Pechal, M","last_name":"Pechal"},{"last_name":"Berger","first_name":"Stefan","full_name":"Berger, Stefan T"},{"first_name":"Andreas","full_name":"Wallraff, Andreas","last_name":"Wallraff"},{"last_name":"Filipp","first_name":"Stefan","full_name":"Filipp, Stefan"}],"month":"04","day":"25"},{"publist_id":"5328","publication":"Physical Review Letters","citation":{"mla":"Nissen, Felix, et al. “Collective Suppression of Linewidths in Circuit QED.” Physical Review Letters, vol. 110, no. 20, American Physical Society, 2013, doi:10.1103/PhysRevLett.110.203602.","apa":"Nissen, F., Fink, J.

We probe the indistinguishability of single photons, created with a controllable delay, in time-resolved second-order cross- and auto-correlation function measurements. Using quadrature amplitude detection we are able to resolve different photon numbers and detect coherence in and between the output arms.

Transport in these junctions is primarily through an unoccupied molecular orbital that is partly hybridized with the Au, which results in splitting the degeneracy of the lowest unoccupied molecular orbital triplet. The transmission through these junctions, however, cannot be modeled by a single Lorentzian resonance, as our results show evidence of quantum interference between an occupied and an unoccupied orbital.

Our design for molecular rectifiers uses a symmetric, conjugated molecular backbone with a single methylsulfide group linking one end to a gold electrode and a covalent gold–carbon bond at the other end. The gold–carbon bond results in a hybrid gold-molecule “gateway” state pinned close to the Fermi level of one electrode. Through nonequilibrium transport calculations, we show that the energy of this state shifts drastically with applied bias, resulting in rectification at surprisingly low voltages. We use this concept to design and synthesize a family of diodes and demonstrate through single-molecule current–voltage measurements that the rectification ratio can be predictably and efficiently tuned. This result constitutes the first experimental demonstration of a rationally tunable system of single-molecule rectifiers. More generally, the results demonstrate that the high-bias properties of “gateway” states can be used to provide additional functionality to molecular electronic systems.","lang":"eng"}],"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"publisher":"American Chemical Society","_id":"17993","date_updated":"2025-01-03T07:57:04Z","external_id":{"pmid":["24274757"]},"title":"Tuning rectification in single-molecular diodes","oa_version":"None","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"month":"11","scopus_import":"1","publication_status":"published","fulldoi":"https://doi.org/10.1021/nl403698m","publication":"Nano Letters","intvolume":" 13","year":"2013","status":"public","extern":"1","issue":"12","type":"journal_article","date_created":"2024-09-09T11:29:47Z","date_published":"2013-11-25T00:00:00Z","page":"6233-6237","author":[{"last_name":"Batra","first_name":"Arunabh","full_name":"Batra, Arunabh"},{"last_name":"Darancet","full_name":"Darancet, Pierre","first_name":"Pierre"},{"last_name":"Chen","full_name":"Chen, Qishui","first_name":"Qishui"},{"last_name":"Meisner","full_name":"Meisner, Jeffrey S.","first_name":"Jeffrey S."},{"full_name":"Widawsky, Jonathan R.","first_name":"Jonathan R.","last_name":"Widawsky"},{"last_name":"Neaton","first_name":"Jeffrey B.","full_name":"Neaton, Jeffrey B."},{"first_name":"Colin","full_name":"Nuckolls, Colin","last_name":"Nuckolls"},{"orcid":"0000-0002-6957-6089","last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","first_name":"Latha","full_name":"Venkataraman, Latha"}],"day":"25","OA_type":"closed access","article_type":"letter_note","pmid":1,"quality_controlled":"1","volume":13},{"date_updated":"2025-01-03T07:59:05Z","_id":"17994","publisher":"American Chemical Society","title":"Ultrafast charge transfer through noncovalent Au–N interactions in molecular systems","publication_identifier":{"eissn":["1932-7455"],"issn":["1932-7447"]},"abstract":[{"lang":"eng","text":"Charge transfer through noncovalent interactions is crucial to a variety of chemical phenomena.

We study the model system 1,4-benzenediamine molecules bound on an Au surface through an Au–N donor–acceptor bond as these are known to provide a pathway for electronic conduction in molecular devices. We study different phases of the molecule/Au system and map charge delocalization times from carbon and nitrogen sites on the molecule. We show that charge delocalization across Au–N donor–acceptor bond occurs in less than 500 as.

We find a broad distribution in the single-molecule conductance of bithiophene compared with that of a methyl sulfide terminated biphenyl. Using a combination of experiments and calculations, we show that this increased breadth in the conductance distribution is explained by the difference in 5-fold symmetry of thiophene rings as compared to the 6-fold symmetry of benzene rings. The reduced symmetry of thiophene rings results in a restriction on the torsion angle space available to these molecules when bound between two metal electrodes in a junction, causing each molecular junction to sample a different set of conformers in the conductance measurements. In contrast, the rotations of biphenyl are essentially unimpeded by junction binding, allowing each molecular junction to sample similar conformers. This work demonstrates that the conductance of bithiophene displays a strong dependence on the conformational fluctuations accessible within a given junction configuration, and that the symmetry of such small molecules can significantly influence their conductance behaviors.","lang":"eng"}],"publication_identifier":{"eissn":["1520-5126"],"issn":["0002-7863"]},"citation":{"mla":"Dell, Emma J., et al. “Impact of Molecular Symmetry on Single-Molecule Conductance.” Journal of the American Chemical Society, vol. 135, no. 32, American Chemical Society, 2013, pp. 11724–27, doi:10.1021/ja4055367.","apa":"Dell, E.

The measured conductance decays exponentially with molecular backbone length with a decay constant that is essentially the same for Ag and Au electrodes. However, the formation and evolution of molecular junctions upon elongation are very different for these two metals. Specifically, junctions formed with Ag electrodes sustain significantly longer elongation when compared with Au due to a difference in the initial gap opened up when the metal point-contact is broken.

We start with molecular backbones (alkanes and oligophenyls) terminated with trimethyltin end groups that cleave off in situ to create junctions where terminal carbons are covalently bonded to the Au electrodes. We apply a thermal gradient across these junctions and measure their conductance and thermopower. Because of the electronic properties of the highly conducting Au–C links, the thermoelectric properties and power factor are very high. Our results show that the molecular thermopower increases nonlinearly with the molecular length while conductance decreases exponentially with increasing molecular length. Density functional theory calculations show that a gateway state representing the Au–C covalent bond plays a key role in the conductance. With this as input, we analyze a series of simplified models and show that a tight-binding model that explicitly includes the gateway states and the molecular backbone states accurately captures the experimentally measured conductance and thermopower trends."}],"publication_identifier":{"issn":["1530-6984"],"eissn":["1530-6992"]},"citation":{"ista":"Widawsky JR, Chen W, Vázquez H, Kim T, Breslow R, Hybertsen MS, Venkataraman L. 2013.

We observe the formation of contacts with a conductance close to 1 G0, the quantum of conductance, which can be attributed to a single-atom contact, similar to those formed by Au. We also find two additional conductance features at ∼0.4 G0 and ∼1.3 G0, which have been previously ascribed to contacts with oxygen contaminations. Here, using a conductance cross-correlation technique, we distinguish three different atomic-scale structural motifs and analyze their rupture forces and stiffness. Our results allow us to assign the ∼0.4 G0 conductance feature to an Ag–O–Ag contact and the ∼1.3 G0 feature to an Ag–Ag single-atom contact with an oxygen atom in parallel. Utilizing complementary information from force and conductance, we thus demonstrate the correlation of conductance with the structural evolution at the atomic scale.","lang":"eng"}],"language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"03","scopus_import":"1","oa_version":"None"},{"publication_status":"published","fulldoi":"https://doi.org/10.1038/nnano.2013.91","publication":"Nature Nanotechnology","intvolume":" 8","year":"2013","status":"public","extern":"1","issue":"6","type":"journal_article","date_created":"2024-09-09T11:35:13Z","date_published":"2013-06-01T00:00:00Z","page":"399-410","author":[{"last_name":"Aradhya","full_name":"Aradhya, Sriharsha V.","first_name":"Sriharsha V."},{"orcid":"0000-0002-6957-6089","last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","first_name":"Latha","full_name":"Venkataraman, Latha"}],"day":"01","OA_type":"closed access","article_type":"original","pmid":1,"quality_controlled":"1","volume":8,"article_processing_charge":"No","doi":"10.1038/nnano.2013.91","citation":{"short":"S.V.

Among these, single-molecule junctions in a metal–molecule–metal motif have contributed significantly to our fundamental understanding of the principles required to realize molecular-scale electronic components from resistive wires to reversible switches. The success of these techniques and the growing interest of other disciplines in single-molecule-level characterization are prompting new approaches to investigate metal–molecule–metal junctions with multiple probes. Going beyond electronic transport characterization, these new studies are highlighting both the fundamental and applied aspects of mechanical, optical and thermoelectric properties at the atomic and molecular scales. Furthermore, experimental demonstrations of quantum interference and manipulation of electronic and nuclear spins in single-molecule circuits are heralding new device concepts with no classical analogues. In this Review, we present the emerging methods being used to interrogate multiple properties in single molecule-based devices, detail how these measurements have advanced our understanding of the structure–function relationships in molecular junctions, and discuss the potential for future research and applications."}],"publisher":"Springer Nature","_id":"17999","date_updated":"2025-01-03T08:10:06Z","external_id":{"pmid":["23736215"]},"title":"Single-molecule junctions beyond electronic transport","oa_version":"None","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"month":"06","scopus_import":"1"},{"oa_version":"None","scopus_import":"1","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"month":"04","publication_identifier":{"isbn":["9783642341403"],"eisbn":["9783642341410"],"issn":["1612-3786"]},"abstract":[{"text":"Motion-based segmentation is an important tool for the analysis of articulated shapes. As such, it plays an important role in mechanical engineering, computer graphics, and computer vision. In this chapter, we study motion-based segmentation of 3D articulated shapes. We formulate motion-based surface segmentation as a piecewise-smooth regularization problem for the transformations between several poses. Using Lie-group representation for the transformation at each surface point, we obtain a simple regularized fitting problem. An Ambrosio-Tortorelli scheme of a generalized Mumford-Shah model gives us the segmentation functional without assuming prior knowledge on the number of parts or even the articulated nature of the object. Experiments on several standard datasets compare the results of the proposed method to state-of-the-art algorithms.","lang":"eng"}],"doi":"10.1007/978-3-642-34141-0_12","citation":{"ieee":"G.
