Magnetic Brightening and Nanoscale Imaging of Spin-Polarized Helical Edge Modes
Samuel Haeuser, Richard H. J. Kim, Lin-Lin Wang +9
Efficient sub-10 nm electric transport remains a major challenge for nanoelectronics due to high losses and impedance mismatches in conventional Drude metals. Despite their promise…
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…
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…
