We observe an increase in superconducting transition temperature for Al and MoSi and a decrease for Nb, NbN, and TiN. In MoSi, ion irradiation also improves the mixing of the two materials.

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.

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."}],"article_type":"original","ddc":["530"],"file_date_updated":"2024-01-29T11:25:38Z","status":"public","oa":1,"date_updated":"2026-09-16T22:30:20Z","author":[{"orcid":"0000-0001-5263-5559","id":"FDE60288-A89D-11E9-947F-1AF6E5697425","first_name":"Soham","full_name":"Mukhopadhyay, Soham","last_name":"Mukhopadhyay"},{"full_name":"Senior, Jorden L","last_name":"Senior","orcid":"0000-0002-0672-9295","first_name":"Jorden L","id":"5479D234-2D30-11EA-89CC-40953DDC885E"},{"last_name":"Saez Mollejo","full_name":"Saez Mollejo, Jaime","first_name":"Jaime","id":"e0390f72-f6e0-11ea-865d-862393336714"},{"full_name":"Puglia, Denise","last_name":"Puglia","first_name":"Denise","id":"4D495994-AE37-11E9-AC72-31CAE5697425","orcid":"0000-0003-1144-2763"},{"id":"2DCF8DE6-F248-11E8-B48F-1D18A9856A87","first_name":"Martin","orcid":"0009-0005-0878-3032","full_name":"Zemlicka, Martin","last_name":"Zemlicka"},{"orcid":"0000-0001-8112-028X","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","first_name":"Johannes M","last_name":"Fink","full_name":"Fink, Johannes M"},{"first_name":"Andrew P","id":"4AD6785A-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2607-2363","last_name":"Higginbotham","full_name":"Higginbotham, Andrew P"}],"month":"11","scopus_import":"1","title":"Superconductivity from a melted insulator in Josephson junction arrays","publication_status":"published","intvolume":"        19","date_published":"2023-11-01T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Springer Nature","project":[{"name":"Cavity electromechanics across a quantum phase transition","_id":"0aa3608a-070f-11eb-9043-e9cd8a2bd931","grant_number":"P33692"},{"grant_number":"754411","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships"},{"name":"Protected states of quantum matter","_id":"eb9b30ac-77a9-11ec-83b8-871f581d53d2"}],"doi":"10.1038/s41567-023-02161-w","_id":"14032","publication_identifier":{"eissn":["1745-2481"],"issn":["1745-2473"]},"day":"01","has_accepted_license":"1","language":[{"iso":"eng"}],"quality_controlled":"1","fulldoi":"https://doi.org/10.1038/s41567-023-02161-w","keyword":["General Physics and Astronomy"],"file":[{"date_updated":"2024-01-29T11:25:38Z","relation":"main_file","creator":"dernst","file_name":"2023_NaturePhysics_Mukhopadhyay.pdf","access_level":"open_access","checksum":"1fc86d71bfbf836e221c1e925343adc5","success":1,"date_created":"2024-01-29T11:25:38Z","content_type":"application/pdf","file_size":1977706,"file_id":"14899"}],"external_id":{"isi":["001054563800006"]},"date_created":"2023-08-11T07:41:17Z","citation":{"ieee":"S.

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"}],"author":[{"first_name":"Duc T","id":"29C8C0B4-F248-11E8-B48F-1D18A9856A87","full_name":"Phan, Duc T","last_name":"Phan"},{"full_name":"Senior, Jorden L","last_name":"Senior","orcid":"0000-0002-0672-9295","first_name":"Jorden L","id":"5479D234-2D30-11EA-89CC-40953DDC885E"},{"full_name":"Ghazaryan, Areg","last_name":"Ghazaryan","first_name":"Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9666-3543"},{"full_name":"Hatefipour, M.","last_name":"Hatefipour","first_name":"M."},{"last_name":"Strickland","full_name":"Strickland, W.

One of the more ubiquitous devices in the current quantum computing toolbox is the transmon-type superconducting quantum bit, embedded in a resonator-based architecture. In the study of heat transport in superconducting circuits, a versatile and sensitive thermometer is based on studying the tunnelling characteristics of superconducting probes weakly coupled to a normal-metal island. Here we show that by integrating superconducting quantum bit coupled to two superconducting resonators at different frequencies, each resonator terminated (and thermally populated) by such a mesoscopic thin film metal island, one can experimentally observe magnetic flux-tunable photonic heat rectification between 0 and 10%.","lang":"eng"}],"oa_version":"Published Version","ddc":["536"],"article_type":"original","publication":"Communications Physics","year":"2020","date_updated":"2024-10-15T12:36:24Z","oa":1,"status":"public","title":"Heat rectification via a superconducting artificial atom","month":"02","author":[{"full_name":"Senior, Jorden L","last_name":"Senior","first_name":"Jorden L","id":"5479D234-2D30-11EA-89CC-40953DDC885E","orcid":"0000-0002-0672-9295"},{"last_name":"Gubaydullin","full_name":"Gubaydullin, Azat","first_name":"Azat"},{"last_name":"Karimi","full_name":"Karimi, Bayan","first_name":"Bayan"},{"first_name":"Joonas T.","last_name":"Peltonen","full_name":"Peltonen, Joonas T."},{"last_name":"Ankerhold","full_name":"Ankerhold, Joachim","first_name":"Joachim"},{"first_name":"Jukka P.","full_name":"Pekola, Jukka P.","last_name":"Pekola"}],"issue":"1","file_date_updated":"2020-07-14T12:48:00Z","intvolume":"         3","publication_status":"published","date_published":"2020-02-25T00:00:00Z","doi":"10.1038/s42005-020-0307-5","article_number":"40","user_id":"0043cee0-e5fc-11ee-9736-f83bc23afbf0","publisher":"Springer Nature"}]
