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"}],"year":"2023","month":"11","ec_funded":1,"status":"public","publication_identifier":{"issn":["1745-2473"],"eissn":["1745-2481"]},"oa":1,"oa_version":"Published Version","date_published":"2023-11-01T00:00:00Z","publication_status":"published","doi":"10.1038/s41567-023-02161-w","intvolume":"        19","citation":{"chicago":"Mukhopadhyay, Soham, Jorden L Senior, Jaime Saez Mollejo, Denise Puglia, Martin Zemlicka, Johannes M Fink, and Andrew P Higginbotham. “Superconductivity from a Melted Insulator in Josephson Junction Arrays.” <i>Nature Physics</i>.
