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…
Observation of the crossover from quantum fluxoid to half-quantum fluxoid in a chiral superconducting device
Masashi Tokuda, Fumiya Matsumoto, Noriaki Maeda +16
Topological superconductors are one of the intriguing material groups from the viewpoint of not only condensed matter physics but also industrial application such as quantum comput…
Magnetic penetration depth in topological superconductors: Effect of Majorana surface states and application for UTe
Kazuki Akuzawa, Jushin Tei, Ryoi Ohashi +2
In this study, we examine how orbital degrees of freedom and Majorana surface states influence the magnetic penetration depth in the superconductor UTe. Using a two-orbital mod…
Two-dimensional flat band on the (011) surface of UTe: Implication for STM measurements with a superconducting tip
Jushin Tei, Takeshi Mizushima, Satoshi Fujimoto
Scanning tunneling microscopy (STM) measurements have been extensively performed on the easily cleavable (011) surface of UTe, using both normal-metal and superconducting tips.…
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…
