Third-harmonic generation in excitonic insulators
Tetsuhiro Tanabe, Tatsuya Kaneko, Yukinori Ohta
We study third-harmonic generation (THG) in an excitonic insulator (EI) described in a two-band correlated electron model. Employing the perturbative expansion with respect to the…

Nonequilibrium dynamics in the pump-probe spectroscopy of excitonic insulators
Tetsuhiro Tanabe, Koudai Sugimoto, Yukinori Ohta
We study the nonequilibrium dynamics in the pump-probe spectroscopy of excitonic insulators using the spinless two-orbital model with phonon degrees of freedom in the time-dependen…
