Unravelling the intertwined atomic and bulk nature of localised excitons by attosecond spectroscopy
Matteo Lucchini, Shunsuke A. Sato, Giacinto D. Lucarelli +9
The electro-optical properties of most semiconductors and insulators of technological interest are dominated by the presence of electron-hole quasiparticles called excitons. The ma…
Role of electron scattering on the high-order harmonic generation from solids
Chang-Ming Wang, Nicolas Tancogne-Dejean, Massimo Altarelli +2
We extend the semi-classical trajectory description for the high-order harmonic generation~(HHG) from solids by integrating the effect of electron-scattering. Comparing the extende…
Nonlinear polarization evolution using time-dependent density functional theory
Mitsuharu Uemoto, Yuki Kuwabara, Shunsuke A. Sato +1
We propose a theoretical and computational approach to investigate temporal behavior of a nonlinear polarization in perturbative regime induced by an intense and ultrashort pulsed…
Ab-initio multi-scale simulation of high-harmonic generation in solids
Isabella Floss, Christoph Lemell, Georg Wachter +5
High-harmonic generation by a highly non-linear interaction of infrared laser fields with matter allows for the generation of attosecond pulses in the XUV spectral regime. This pro…
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…
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…
