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…
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…
Cavity-altered superconductivity
Itai Keren, Tatiana A. Webb, Shuai Zhang +30
Is it feasible to alter the ground state properties of a material by engineering its electromagnetic environment? Inspired by theoretical predictions, experimental realizations of…
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…
High-resolution Measurements of Thermal Conductivity Matrix and Search for Thermal Hall Effect in LaCuO
Jiayi Hu, Haozhi Xu, Juntao Yao +3
We investigated the longitudinal thermal conductivity and thermal hall conductivity in LaCuO at temperatures between 2 and 20 K in magnetic fields $…
