Intrinsic magnetization of the superconducting condensate in Fe(Te,Se)
Mohammad Javadi Balakan, Shiva Heidari, Genda Gu +4
A spin-polarized superconducting condensate generates a net magnetization with measurable signatures. We present evidence for an intrinsic magnetic field in mesoscopic Fe(Te,Se) ri…
Coupling of Klein-Andreev Resonant States in BiSrCaCuO-graphene-BiSrCaCuO Devices
Sharadh Jois, Jose L. Lado, Genda Gu +2
Quantum devices require coherent coupling over macroscopic distances. Recently, resonances due to Klein tunneling and Andreev reflection states (KARS) have been observed in a natur…
Aharonov-Bohm interference from coherent spin-polarized edge transport in Fe(Te,Se) superconducting rings
Mohammad Javadi Balakan, Shiva Heidari, Genda Gu +4
We report the coexistence of Aharonov-Bohm and Little-Parks oscillations in mesoscopic Fe(Te,Se) rings. The magnetoresistance shows two distinct periodicities: an component f…
Observation of Half-Quantum Vorticity in an Iron-based Superconductor
Mohammad Javadi Balakan, Genda Gu, Qiang Li +3
Half-quantum vortices -- topological excitations carrying half the superconducting flux quantum -- are predicted to emerge in spin-triplet superconductors, where the spin component…
