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…
Ferromagnetic resonance modulation in -wave superconductor/ferromagnetic insulator bilayer systems
Yuya Ominato, Ai Yamakage, Takeo Kato +1
We investigate ferromagnetic resonance (FMR) modulation in -wave superconductor (SC)/ferromagnetic insulator (FI) bilayer systems theoretically. The modulation of the Gilbert da…
Photovoltaic anomalous Hall effect in line-node semimetals
Katsuhisa Taguchi, Dong-Hui Xu, Ai Yamakage +1
We theoretically study the circularly polarized light-induced Floquet state in line-node semimetals with time-reversal symmetry and inversion symmetry. It is found that the Floquet…
Majorana Braiding Dynamics on Nanowires
Cássio Sozinho Amorim, Kazuto Ebihara, Ai Yamakage +2
Superconductors hosting long-sought excitations called Majorana fermions may be ultimately used as qubits of fault-tolerant topological quantum computers. A crucial challenge towar…
Quantum thermal Hall effect of Majorana fermions on the surface of superconducting topoloigcal insulators
Yosuke Shimizu, Ai Yamakage, Kentaro Nomura
We study the quantum anomalous thermal Hall effect in a topological superconductor which possesses an integer bulk topological number, and supports Majorana excitations on the surf…
