Here we report the fabrication of gate-defined symmetry-broken Josephson junctions in magic-angle twisted bilayer graphene, where the weak link is gate-tuned close to the correlated insulator state with a moiré filling factor of υ = −2. We observe a phase-shifted and asymmetric Fraunhofer pattern with a pronounced magnetic hysteresis. Our theoretical calculations of the junction weak link—with valley polarization and orbital magnetization—explain most of these unconventional features. The effects persist up to the critical temperature of 3.5 K, with magnetic hysteresis observed below 800 mK. We show how the combination of magnetization and its current-induced magnetization switching allows us to realise a programmable zero-field superconducting diode. Our results represent a major advance towards the creation of future superconducting quantum electronic devices."}],"article_type":"original","citation":{"chicago":"Díez-Mérida, J., A.

Here we report a study of the transport and microwave response of Josephson arrays with interactions exceeding this level. Contrary to expectations, we observe that the array resistance drops dramatically as the temperature is decreased—reminiscent of superconducting behaviour—and then saturates at low temperature. Applying a magnetic field, we eventually observe a transition to a highly resistive regime. These observations can be understood within a theoretical picture that accounts for the effect of thermal fluctuations on the insulating phase. On the basis of the agreement between experiment and theory, we suggest that apparent superconductivity in our Josephson arrays arises from melting the zero-temperature insulator.","lang":"eng"}],"intvolume":" 19","ddc":["530"],"status":"public","title":"Superconductivity from a melted insulator in Josephson junction arrays","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14032","oa_version":"Published Version","file":[{"creator":"dernst","content_type":"application/pdf","file_size":1977706,"access_level":"open_access","file_name":"2023_NaturePhysics_Mukhopadhyay.pdf","success":1,"checksum":"1fc86d71bfbf836e221c1e925343adc5","date_updated":"2024-01-29T11:25:38Z","date_created":"2024-01-29T11:25:38Z","file_id":"14899","relation":"main_file"}],"publication_identifier":{"eissn":["1745-2481"],"issn":["1745-2473"]},"month":"11","project":[{"grant_number":"P33692","_id":"0aa3608a-070f-11eb-9043-e9cd8a2bd931","name":"Cavity electromechanics across a quantum phase transition"},{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"},{"name":"Protected states of quantum matter","_id":"eb9b30ac-77a9-11ec-83b8-871f581d53d2"},{"name":"Protected states of quantum matter","_id":"bd5b4ec5-d553-11ed-ba76-a6eedb083344"}],"isi":1,"quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"external_id":{"isi":["001054563800006"]},"language":[{"iso":"eng"}],"acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"doi":"10.1038/s41567-023-02161-w","ec_funded":1,"file_date_updated":"2024-01-29T11:25:38Z","department":[{"_id":"GradSch"},{"_id":"AnHi"},{"_id":"JoFi"}],"publisher":"Springer Nature","publication_status":"published","acknowledgement":"We thank D.

Spin-orbit coupling, combined with the proximity effect, causes the two-dimensional semiconductor to inherit p±ip intraband pairing, and application of magnetic field can then result in transitions to the normal state, partial Bogoliubov Fermi surfaces, or topological phases with Majorana modes. Experimentally probing the hybrid superconductor-semiconductor interface is challenging due to the shunting effect of the conventional superconductor. Consequently, the nature of induced pairing remains an open question. Here, we use the circuit quantum electrodynamics architecture to probe induced superconductivity in a two dimensional Al-InAs hybrid system. We observe a strong suppression of superfluid density and enhanced dissipation driven by magnetic field, which cannot be accounted for by the depairing theory of an s-wave superconductor. These observations are explained by a picture of independent intraband p±ip superconductors giving way to partial Bogoliubov Fermi surfaces, and allow for the first characterization of key properties of the hybrid superconducting system.","lang":"eng"}],"department":[{"_id":"MaSe"},{"_id":"AnHi"},{"_id":"MiLe"}],"publication_status":"submitted","status":"public","title":"Breakdown of induced p±ip pairing in a superconductor-semiconductor hybrid","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"10029","year":"2021","acknowledgement":"This research was supported by the Scientific Service Units of IST Austria through resources provided by the MIBA Machine Shop and the nanofabrication facility.

Here, we study theoretically a three-terminal setup, with two normal leads coupled to a grounded superconducting terminal. Using a single-electron scattering matrix, we derive the subgap conductance matrix for the normal leads and discuss its symmetries. In particular, we show that the local and the nonlocal elements of the conductance matrix have pairwise identical antisymmetric components. Moreover, we find that the nonlocal elements are directly related to the local BCS charges of the bound states close to the normal probes and we show how the BCS charge of overlapping Majorana bound states can be extracted from experiments.","lang":"eng"}],"issue":"3","type":"journal_article","oa_version":"Preprint","title":"Nonlocal conductance spectroscopy of Andreev bound states: Symmetry relations and BCS charges","status":"public","intvolume":" 124","_id":"7478","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"24","article_processing_charge":"No","date_published":"2020-01-24T00:00:00Z","article_type":"original","publication":"Physical Review Letters","citation":{"ama":"Danon J, Hellenes AB, Hansen EB, Casparis L, Higginbotham AP, Flensberg K.

Operating at T < 100 mK temperatures, as required for quantum electrical circuits, we demonstrate a mechanically mediated microwave–optical converter with 47% conversion efficiency, and use a classical feed-forward protocol to reduce added noise to 38 photons. The feed-forward protocol harnesses our discovery that noise emitted from the two converter output ports is strongly correlated because both outputs record thermal motion of the same mechanical mode. We also discuss a quantum feed-forward protocol that, given high system efficiencies, would allow quantum information to be transferred even when thermal phonons enter the mechanical element faster than the electro-optic conversion rate.","lang":"eng"}],"issue":"10","quality_controlled":"1","page":"1038-1042","publication":"Nature Physics","citation":{"ista":"Higginbotham AP, Burns PS, Urmey MD, Peterson RW, Kampel NS, Brubaker BM, Smith G, Lehnert KW, Regal CA. 2018.

They are expected to exhibit non-Abelian particle statistics, in contrast to the usual statistics of fermions and bosons, enabling quantum operations to be performed by braiding isolated modes around one another. Quantum braiding operations are topologically protected insofar as these modes are pinned near zero energy, with the departure from zero expected to be exponentially small as the modes become spatially separated. Following theoretical proposals, several experiments have identified signatures of Majorana modes in nanowires with proximity-induced superconductivity and atomic chains, with small amounts of mode splitting potentially explained by hybridization of Majorana modes. Here, we use Coulomb-blockade spectroscopy in an InAs nanowire segment with epitaxial aluminium, which forms a proximity-induced superconducting Coulomb island (a â ∼ Majorana islandâ (tm)) that is isolated from normal-metal leads by tunnel barriers, to measure the splitting of near-zero-energy Majorana modes. We observe exponential suppression of energy splitting with increasing wire length. For short devices of a few hundred nanometres, sub-gap state energies oscillate as the magnetic field is varied, as is expected for hybridized Majorana modes. Splitting decreases by a factor of about ten for each half a micrometre of increased wire length. For devices longer than about one micrometre, transport in strong magnetic fields occurs through a zero-energy state that is energetically isolated from a continuum, yielding uniformly spaced Coulomb-blockade conductance peaks, consistent with teleportation via Majorana modes. Our results help to explain the trivial-to-topological transition in finite systems and to quantify the scaling of topological protection with end-mode separation."}],"issue":"7593","title":"Exponential protection of zero modes in Majorana islands","status":"public","intvolume":" 531","_id":"101","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","oa_version":"Submitted Version"},{"author":[{"full_name":"Mishmash, Ryan","last_name":"Mishmash","first_name":"Ryan"},{"full_name":"Aasen, David","last_name":"Aasen","first_name":"David"},{"full_name":"Higginbotham, Andrew P","last_name":"Higginbotham","first_name":"Andrew P","orcid":"0000-0003-2607-2363","id":"4AD6785A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Alicea, Jason","last_name":"Alicea","first_name":"Jason"}],"oa_version":"Preprint","volume":93,"date_updated":"2021-01-12T06:47:42Z","date_created":"2018-12-11T11:44:38Z","year":"2016","_id":"102","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","intvolume":" 93","publisher":"American Physical Society","title":"Approaching a topological phase transition in Majorana nanowires","status":"public","publication_status":"published","publist_id":"7952","issue":"24","abstract":[{"text":"Recent experiments have produced mounting evidence of Majorana zero modes in nanowire-superconductor hybrids. Signatures of an expected topological phase transition accompanying the onset of these modes nevertheless remain elusive. We investigate a fundamental question concerning this issue: Do well-formed Majorana modes necessarily entail a sharp phase transition in these setups? Assuming reasonable parameters, we argue that finite-size effects can dramatically smooth this putative transition into a crossover, even in systems large enough to support well-localized Majorana modes. We propose overcoming such finite-size effects by examining the behavior of low-lying excited states through tunneling spectroscopy. In particular, the excited-state energies exhibit characteristic field and density dependence, and scaling with system size, that expose an approaching topological phase transition. We suggest several experiments for extracting the predicted behavior. As a useful byproduct, the protocols also allow one to measure the wire's spin-orbit coupling directly in its superconducting environment.","lang":"eng"}],"extern":"1","type":"journal_article","article_number":"245404","date_published":"2016-06-08T00:00:00Z","doi":"10.1103/PhysRevB.93.245404","language":[{"iso":"eng"}],"external_id":{"arxiv":["1601.07908"]},"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1601.07908"}],"citation":{"apa":"Mishmash, R., Aasen, D., Higginbotham, A.

Arguably the most important advantage of organic NLO materials, relative to traditionally used inorganic NLO materials, is their short optical response time. Geminal amido esters with their donor-π-acceptor (D-π-A) architecture exhibit high levels of electron delocalization and substantial intramolecular charge transfer, which should endow these materials with short optical response times and large molecular (hyper)polarizabilities. In order to test this hypothesis, the linear and second-order nonlinear optical properties of five geminal amido esters, (E)-ethyl 3-(X-phenylamino)-2-(Y-phenylcarbamoyl)acrylate (1, X = 4-H, Y = 4-H; 2, X = 4-CH3, Y = 4-CH3; 3, X = 4-NO2, Y = 2,5-OCH3; 4, X = 2-Cl, Y = 2-Cl; 5, X = 4-Cl, Y = 4-Cl) were synthesized and characterized, whereby NLO structure-function relationships were established including intramolecular charge transfer characteristics, crystal field effects, and molecular first hyperpolarizabilities (β). Given the typically large errors (10-30%) associated with the determination of β coefficients, three independent methods were used: (i) density functional theory, (ii) hyper-Rayleigh scattering, and (iii) high-resolution X-ray diffraction data analysis based on multipolar modeling of electron densities at each atom. These three methods delivered consistent values of β, and based on these results, 3 should hold the most promise for NLO applications. The correlation between the molecular structure of these geminal amido esters and their linear and nonlinear optical properties thus provide molecular design guidelines for organic NLO materials; this leads to the ultimate goal of generating bespoke organic molecules to suit a given NLO device application."}],"issue":"51","publist_id":"7962","extern":"1","type":"journal_article","date_published":"2016-12-05T00:00:00Z","doi":"10.1021/acs.jpcc.6b10724","language":[{"iso":"eng"}],"publication":"Journal of Physical Chemistry C","citation":{"ama":"Cole J, Lin T, Ashcroft C, et al.

To this end, we use a system comprising a gate-confined semiconductor nanowire with an epitaxially grown superconductor layer, yielding an isolated, proximitized nanowire segment.

The molecular charge-transfer distribution is topographically mapped, demonstrating that a uniformly delocalized passive electronic medium facilitates the charge-transfer between the phenolic electron donor and the cyano electron acceptors which lie at opposite ends of the molecule. Its ability to act as a “push–pull” π-conjugated molecule is quantified, relative to similar materials, by supporting empirical calculations; these include bond-length alternation and harmonic-oscillator stabilization energy (HOSE) tests. Such tests, together with frontier molecular orbital considerations, reveal that OH1 can exist readily in its aromatic (neutral) or quinoidal (charge-separated) state, thereby overcoming the “nonlinearity-thermal stability trade-off”. The HOSE calculation also reveals a correlation between the quinoidal resonance contribution to the overall structure of OH1 and the UV–vis absorption peak wavelength in the wider family of configurationally locked polyene framework materials. Solid-state tensorial coefficients of the molecular dipole, polarizability, and the first hyperpolarizability for OH1 are derived from the first-, second-, and third-order electronic moments of the experimental charge-density distribution. The overall solid-state molecular dipole moment is compared with those from gas-phase calculations, revealing that crystal field effects are very significant in OH1. The solid-state hyperpolarizability derived from this charge-density study affords good agreement with gas-phase calculations as well as optical measurements based on hyper-Rayleigh scattering (HRS) and electric-field-induced second harmonic (EFISH) generation. This lends support to the further use of charge-density studies to calculate solid-state hyperpolarizability coefficients in other organic NLO materials. Finally, this charge-density study is also employed to provide an advanced classification of hydrogen bonds in OH1, which requires more stringent criteria than those from conventional structure analysis. As a result, only the strongest OH···NC interaction is so classified as a true hydrogen bond. Indeed, it is this electrostatic interaction that influences the molecular charge transfer: the other four, weaker, nonbonded contacts nonetheless affect the crystal packing. Overall, the establishment of these structure–property relationships lays a blueprint for designing further, more NLO efficient, materials in this industrially leading organic family of compounds.","lang":"eng"}],"page":"9416-9430","quality_controlled":"1","citation":{"ama":"Lin T-C, Cole JM, Higginbotham AP, et al.

The submerged oscillator atomizes the fluid, creating droplets with radii proportional to the wavelength of the standing wave at the fluid surface. Classical theory for the Faraday instability predicts a parametric instability driving a capillary wave at the subharmonic (ω / 2) frequency. For many applications it is desirable to reduce the size of the droplets; however, using higher frequency oscillators becomes impractical beyond a few MHz. Observations are presented that demonstrate that smaller droplets may also be created by increasing the driving amplitude of the oscillator, and that this effect becomes more pronounced for large driving frequencies. It is shown that these observations are consistent with a transition from droplets associated with subharmonic (ω/2) capillary waves to harmonic (ω) capillary waves induced by larger driving frequencies and amplitudes, as predicted by a stability analysis of the capillary waves.","lang":"eng"}],"publist_id":"7964","issue":"5","type":"journal_article"},{"day":"20","month":"07","language":[{"iso":"eng"}],"doi":"10.1021/am100375w","date_published":"2010-07-20T00:00:00Z","page":"2360 - 2364","quality_controlled":"1","citation":{"chicago":"Wright, Ian, Andrew P Higginbotham, Shenda Baker, and Tom Donnelly. “Generation of Nanoparticles of Controlled Size Using Ultrasonic Piezoelectric Oscillators in Solution.” ACS Applied Materials and Interfaces.
