Strong-Field Perspective on High-Harmonic Radiation from Bulk Solids
Takuya Higuchi, Mark I. Stockman, Peter Hommelhoff
Mechanisms of high-harmonic generation from crystals are described by treating the electric field of a laser as a quasi-static strong field. Under the quasi-static electric field,…
Wannier-Stark states of graphene monolayer in strong electric field
Hamed Koochaki Kelardeh, Vadym Apalkov, Mark I. Stockman
We find theoretically energy spectrum of a graphene monolayer in a strong constant electric field using a tight-binding model. Within a single band, we find quantized equidistant e…
Interaction of graphene monolayer with ultrashort laser pulse
Hamed Koochaki Kelardeh, Vadym Apalkov, Mark I. Stockman
We study the interaction of graphene with ultrashort few femtosecond long optical pulse. For such a short pulse, the electron dynamics is coherent and is described within the tight…
