Frustrated edge currents in bilayers formed of s- and d-wave superconductors
Vedangi Pathak, Oguzhan Can, Nirek Brahmbhatt +1
We explore edge currents in heterostructures formed of a high- cuprate and a conventional -wave superconductors. The resulting superconductor spontaneously breaks…
NMon: enhanced transmon qubit based on parallel arrays of Josephson junctions
Oguzhan Can, Marcel Franz
We introduce a novel superconducting qubit architecture utilizing parallel arrays of Josephson junctions. This design offers a substantialy improved relative anharmonicity, typical…
Edge currents as probe of topology in twisted cuprate bilayers
Vedangi Pathak, Oguzhan Can, Marcel Franz
Bilayers made of high- cuprate superconductor BiSrCaCuO assembled with a twist angle close to have been recently shown to spontaneously break ti…
Quantum-Geometric Origin of Out-of-plane Stacking Ferroelectricity
Benjamin T. Zhou, Vedangi Pathak, Marcel Franz
Stacking ferroelectricity (SFE) has been discovered in a wide range of van der Waals materials and holds promise for applications, including photovoltaics and high-density memory d…
