Quantum Geometric Origin of Hall Viscosity and Nonlocal Hall Conductivity in Lattice Bands
Danyu Shu, Ryotaro Sano, Ai Yamakage +2
We show that Hall viscosity in lattice bands is governed by a band-projected electric quadrupole encoded within the quantum geometry: Berry curvature sets the projected-coordinate…
Gyromagnetic Quantum Friction in Rayleigh Vorticity Baths
Mamoru Matsuo, Ryotaro Sano, Ai Yamakage +2
We identify an intrinsic zero-temperature relaxation channel for near-surface spins gyromagnetically coupled to Rayleigh-wave vorticity. This surface-mode contribution requires no…
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…
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…
