Inverse Spin Hall Effect in Nonequilibrium Dirac Systems Induced by Anomalous Flow Imbalance
Hung-Hsuan Teh, Tokiro Numasawa, Shun Okumura +1
We study Dirac fermions in the presence of a space-dependent chiral gauge field and thermodynamic gradients, establishing a connection to the inverse spin Hall effect. The chiral g…

Many-body Keldysh Crossover in the DC-driven Haldane Spin Chain
Koichi Okazaki, Shun Okumura, Shintaro Takayoshi +1
We theoretically study nonlinear processes driven by a DC spin-electric field in the antiferromagnetic spin-1 Heisenberg model starting from the ground state in the Haldane phase.…
