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…
Stability of Majorana Fermions in Proximity-Coupled Topological Insulator Nanowires
A. M. Cook, M. M. Vazifeh, M. Franz
It has been shown previously that a finite-length topological insulator nanowire, proximity-coupled to an ordinary bulk s-wave superconductor and subject to a longitudinal applied…
Quasiparticles and Vortices in Unconventional Superconductors
O. Vafek, A. Melikyan, M. Franz +1
Quasiparticles in the vortex lattice of strongly type-II superconductors are investigated by means of a singular gauge transformation applied to the tight binding lattice Bogoliubo…
