Valley Hall Viscosity in Gapped Graphene with and without a Magnetic Field
Danyu Shu, Hiroshi Funaki, Ai Yamakage +2
Hall viscosity is conventionally defined through the stress response to time-dependent strain, a perturbation that is difficult to implement in solid-state experiments. We formulat…
Superconducting Gap Structures in Wallpaper Fermion Systems
Kaito Yoda, Ai Yamakage
We theoretically investigate the superconducting gap structures in wallpaper fermions, which are surface states of topological nonsymmorphic crystalline insulators, based on a two-…
Symmetry-adapted models for multifold fermions with spin-orbit coupling
Koki Satow, Ai Yamakage
Multifold fermions, quasiparticles with multiple degeneracy protected by crystalline symmetries, exhibit a variety of intriguing phenomena stemming from their large topological cha…
Spin Pumping into two-dimensional systems
Yuya Ominato, Masaki Yama, Ai Yamakage +2
In this review, we present recent theoretical developments on spin transport phenomena probed by ferromagnetic resonance (FMR) modulation in two-dimensional systems coupled to magn…
Magnon-mediated superconductivity on ferromagnetic wallpaper fermions
Koki Mizuno, Ai Yamakage
We study two-dimensional superconductivity mediated by magnetic fluctuations at the interface between a ferromagnetic insulator and the nonsymmorphic topological crystalline insula…
Directional propagation of quantum Hall viscous fluid by nano-structural engineering
Hiroshi Funaki, Ai Yamakage, Ryotaro Sano +1
We present a microscopic theory of the viscous electron fluid in the quantum Hall state based on the nonequilibrium Green's function method and the von Neumann lattice representati…
