Dynamical Majorana Ising spin response in a topological superconductor-magnet hybrid by microwave irradiation
Yuya Ominato, Ai Yamakage, Mamoru Matsuo
We study a dynamical spin response of surface Majorana modes in a topological superconductor-magnet hybrid under microwave irradiation. We find a method to toggle between dissipati…
Hall effect of ferro/antiferromagnetic wallpaper fermions
Koki Mizuno, Ai Yamakage
Nonsymmorphic crystals can host characteristic double surface Dirac cones with fourfold degeneracy on the Dirac points, called wallpaper fermion, protected by wallpaper group symme…
Microscopic Theory of Nonlinear Hall Effect Induced by Electric Field and Temperature Gradient
Terufumi Yamaguchi, Kazuki Nakazawa, Ai Yamakage
Electric current flows parallel to the outer product of an applied electric field and temperature gradient, a phenomenon we call the nonlinear chiral thermo-electric (NCTE) Hall ef…
Electrical conductivity and screening effect of spin-1 chiral fermions scattered by charged impurities
Risako Kikuchi, Ai Yamakage
We theoretically study the quantum transport in a three-dimensional spin-1 chiral fermion system in the presence of coulomb impurities based on the self-consistent Born approximati…
Curvature-induced valley-dependent spin-orbit interaction
A. Yamakage, T. Sato, R. Okuyama +5
We construct a general theoretical framework for describing curvature-induced spin-orbit interactions on the basis of group theory. Our theory can systematically determine the emer…
Majorana Spin Current Generation by Dynamic Strain
Yuki Yamazaki, Takumi Funato, Ai Yamakage
Majorana fermions that emerge on the surface of topological superconductors are charge neutral but can have higher-rank electric multipoles by allowing for account time-reversal an…
Anisotropic spin-current spectroscopy of ferromagnetic superconducting gap symmetries
Hiroshi Funaki, Ai Yamakage, Mamoru Matsuo
We develop a microscopic theory of tunneling spin transport at the magnetic interface between a ferromagnetic insulator and a ferromagnetic superconductor (FSC) driven by ferromagn…
