Diagrammatic study of optical excitations in correlated systems
Olivier Simard, Shintaro Takayoshi, Philipp Werner
The optical conductivity contains relevant information on the properties of correlated electron systems. In infinite dimensions, where dynamical mean field theory becomes exact, ve…
High-harmonic generation in one-dimensional Mott insulator
Yuta Murakami, Shintaro Takayoshi, Akihisa Koga +1
We study high-harmonic generation (HHG) in the one-dimensional Hubbard model in order to understand its relation to elementary excitations as well as the similarities and differenc…
Nonadiabatic Nonlinear Optics and Quantum Geometry -- Application to the Twisted Schwinger Effect
Shintaro Takayoshi, Jianda Wu, Takashi Oka
We study the tunneling mechanism of nonlinear optical processes in solids induced by strong coherent laser fields. The theory is based on an extension of the Landau-Zener model wit…
Optomagnonic Barnett effect
Kouki Nakata, Shintaro Takayoshi
Combining the technologies of quantum optics and magnonics, we find that the circularly polarized laser can dynamically realize the quasiequilibrium magnon Bose-Einstein condensate…
