Photoinduced dynamics in an excitonic insulator is studied theoretically by using a two-
orbital Hubbard model on the square lattice where the excitonic phase in the ground state is …

Different from the high-order harmonic generation (HHG) from gases, we find that the yield of
HHG from solids exhibits unexpected modulations as a function of the driving laser intensity …

Charge acceleration during an intense light field application to solids attracts much attention
as elementary processes in high-harmonic generation and photoelectron emission. For …

Application of an intense light field to solids produces enormous and ultrafast nonlinear
phenomena such as high-harmonic generation, and attosecond charge dynamics,. These …

We have demonstrated transient charge localization effects with a driving high-frequency
field of 7 fs, 1.5-cycle near-infrared light in correlated organic conductors. In a layered …

Motivated by recent experimental findings for an organic superconductor, charge oscillations
that emerge after a strong pulse of an oscillating electric field is applied are studied in …

Photoinduced charge dynamics in dimerized systems is studied on the basis of the exact
diagonalization method and the time-dependent Schrödinger equation for a one …

We present a theoretical investigation of the dynamics induced by higher-frequency off-
resonant light pulse excitation in the metallic phase of κ-(BEDT-TTF) 2 X [where BEDT-TTF …

We investigate the condition for the photoinduced enhancement of an excitonic order in a
two-orbital Hubbard model, which has been theoretically proposed in our previous work …

We report an observation of stimulated emission induced by a nearly single-cycle 6 fs near
infrared electric field of 10 MV cm− 1 in an organic superconductor (κ-(h-ET) 2Cu [N (CN) 2] …
