Time-dependent Hartree-Fock study of electron-hole interaction effects on high-harmonic generation from periodic crystals
Takuya Ikemachi, Yasushi Shinohara, Takeshi Sato +3
We investigate the multielectron effects on high-harmonic generation from solid-state materials using the time-dependent Hartree-Fock theory. We find qualitative change in harmonic…
Trajectory analysis of high-harmonic generation from periodic crystals
Takuya Ikemachi, Yasushi Shinohara, Takeshi Sato +3
We theoretically study high-harmonic generation (HHG) from solids driven by intense laser pulses using a one-dimensional model periodic crystal. By numerically solving the time-dep…
Appropriate probe condition for absorption imaging of ultracold Li atoms
Munekazu Horikoshi, Aki Ito, Takuya Ikemachi +3
One of the readily accessible observables in trapped cold-atom experiments is the column density, which is determined from optical depth (OD) obtained from absorption imaging and t…
All-optical production of a superfluid Bose-Fermi mixture of Li and Li
Takuya Ikemachi, Aki Ito, Yukihito Aratake +4
We report the first all-optical production of a superfluid Bose-Fermi mixture with two spin states of Li (fermion) and one spin state of Li (boson) under the resonant magne…
