Ensemble properties of charge carriers injected by an ultrashort laser pulse
Muhammad Qasim, Michael S. Wismer, Manoram Agarwal +1
The average effective mass of charge carriers produced by an intense ultrashort laser pulse in a transparent solid increases significantly as the excitation mechanism changes from…
Adiabatic corrections for velocity-gauge simulations of electron dynamics in periodic potentials
Vladislav S. Yakovlev, Michael S. Wismer
We show how to significantly reduce the number of energy bands required to model the interaction of light with crystalline solids in the velocity gauge. We achieve this by deriving…
Ultrafast optical Faraday effect in transparent solids
Michael S. Wismer, Mark I. Stockman, Vladislav S. Yakovlev
We predict a strong-field ultrafast optical Faraday effect, where a circularly polarized ultrashort optical pulse induces transient chirality in an achiral transparent dielectric.…
Strong-Field Resonant Dynamics in Semiconductors
Michael S. Wismer, Stanislav Yu. Kruchinin, Marcelo Ciappina +2
We predict that a direct bandgap semiconductor (GaAs) resonantly excited by a strong ultrashort laser pulse exhibits a novel regime: kicked anharmonic Rabi oscillations (KARO). In…
