Quantum-geometric shift of quasiequilibrium: Origin of nonreciprocal current driven by quantum-metric dipole
Sota Kitamura, Takahiro Anan, Takahiro Morimoto
We study nonlinear DC electric transport of quantum-metric origin by combining adiabatic perturbation theory with the nonequilibrium Green function approach. The adiabatic ansatz p…
Nonreciprocal current induced by dissipation in time-reversal symmetric systems
Takahiro Anan, Sota Kitamura, Takahiro Morimoto
We study nonreciprocal current response in noncentrosymmetric crystals under time-reversal symmetry. We reveal that the nonreciprocal current appears in a dissipative system throug…
Problem of nonlinear conductivity within relaxation time approximation in noncentrosymmetric insulators
Ibuki Terada, Sota Kitamura, Hiroshi Watanabe +1
With the recent advancements in laser technology, there has been increasing interest in nonlinear and nonperturbative phenomena such as nonreciprocal transport, the nonlinear Hall…
Multi-tunneling effect of nonreciprocal Landau-Zener tunneling: Insights from DC field responses
Ibuki Terada, Sota Kitamura, Hiroshi Watanabe +1
Recent advancements in laser technology have spurred growing interest in nonlinear and nonequilibrium phenomena. Here, we investigate the geometric aspects of quantum tunneling and…
