Nonlinear electronic excitations in crystalline solids using meta-generalized gradient approximation and hybrid functional in time-dependent density functional theory
Shunsuke A. Sato, Yasutaka Taniguchi, Yasushi Shinohara +1
We develop numerical methods to calculate electron dynamics in crystalline solids in real-time time-dependent density functional theory employing exchange-correlation potentials wh…
Observation of molecular dipole excitations by attosecond self-streaking
Georg Wachter, Stefan Nagele, Shunsuke A. Sato +6
We propose a protocol to probe the ultrafast evolution and dephasing of coherent electronic excitation in molecules in the time domain by the intrinsic streaking field generated by…
Femtosecond time-resolved dynamical Franz-Keldysh effect
T. Otobe, Y. Shinohara, S. A. Sato +1
We theoretically investigate the dynamical Franz-Keldysh effect in femtosecond time resolution, that is, the time-dependent modulation of a dielectric function at around the band g…
Controlling ultrafast currents by the non-linear photogalvanic effect
Georg Wachter, Shunsuke A. Sato, Christoph Lemell +3
We theoretically investigate the effect of broken inversion symmetry on the generation and control of ultrafast currents in a transparent dielectric (SiO2) by strong femto-second o…
