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.…

Many-body effects on high-harmonic generation in Hubbard ladders
Yuta Murakami, Thomas Hansen, Shintaro Takayoshi +2
We show how many-body effects associated with background spin dynamics control the high-harmonic generation (HHG) in Mott insulators by analyzing the two-leg ladder Hubbard model.…
