Photocurrent of exciton polaritons
Takahiro Morimoto, Naoto Nagaosa
We study photocurrent of exciton polaritons in inversion broken systems. We use an effective Hamiltonian and Green's function approaches to deduce the formula for polariton photocu…
Current response of nonequilibrium steady states in Landau-Zener problem: Nonequilibrium Green's function approach
Sota Kitamura, Naoto Nagaosa, Takahiro Morimoto
The carrier generation in insulators subjected to strong electric fields is characterized by the Landau-Zener formula for the tunneling probability with a nonperturbative exponent.…
Current-induced second harmonic generation in inversion-symmetric Dirac and Weyl semimetals
Kazuaki Takasan, Takahiro Morimoto, Joseph Orenstein +1
Second harmonic generation (SHG) is a fundamental nonlinear optical phenomenon widely used both for experimental probes of materials and for application to optical devices. Even-or…
Optical rotation in thin chiral/twisted materials and the gyrotropic magnetic effect
Yan-Qi Wang, Takahiro Morimoto, Joel E. Moore
The rotation of the plane of polarization of light passing through a non-magnetic material is known as natural optical activity or optical gyrotropy. The behavior of this effect in…
