Theory of Andreev and shot noise spectroscopy for topological superconductors probed by -wave superconducting tips
Jushin Tei, Ryo Hanai, Satoshi Fujimoto +1
Scanning tunneling microscopy (STM) and spectroscopy (STS) with -wave superconducting tips has been widely applied to probe exotic superconductors, but its potential for investi…
Intrinsic spin Nernst effect in spin-triplet superconductors
Taiki Matsushita, Youichi Yanase, Takeshi Mizushima +2
We theoretically investigate the intrinsic (impurity-independent) spin Nernst effect (SNE), a spin current generation perpendicular to temperature gradients, in spin-triplet superc…
Optical-vortex-pulse induced nonequilibrium spin textures in spin-orbit coupled electrons
Shunki Yamamoto, Masahiro Sato, Satoshi Fujimoto +1
Optical vortex beams are a type of topological light characterized by their inherent orbital angular momentum, leading to the propagation of a spiral-shaped wavefront. In this stud…
Detecting Topological Phase Transition in Superconductor-Semiconductor Hybrids by Electronic Raman Spectroscopy
Takeshi Mizushima, Yukio Tanaka, Jorge Cayao
In superconductor-semiconductor hybrids, applying a magnetic field closes a trivial bulk gap and causes a topological phase transition (TPT), resulting in the emergence of Majorana…
