Enhancement of high-order harmonic generation in graphene by mid-infrared and terahertz fields
Wenwen Mao, Angel Rubio, Shunsuke A. Sato
We theoretically investigate high-order harmonic generation (HHG) in graphene under mid-infrared (MIR) and terahertz (THz) fields based on a quantum master equation. Numerical simu…
Revealing Ultrafast Phonon Mediated Inter-Valley Scattering through Transient Absorption and High Harmonic Spectroscopies
Kevin Lively, Shunsuke A. Sato, Guillermo Albareda +2
Processes involving ultrafast laser driven electron-phonon dynamics play a fundamental role in the response of quantum systems in a growing number of situations of interest, as evi…
Frequency-resolved microscopic current density analysis of linear and nonlinear optical phenomena in solids
Shunsuke A. Sato
We perform a frequency-resolved analysis of electron dynamics in solids to obtain microscopic insight into linear and nonlinear optical phenomena. For the analysis, we first comput…
Optimizing Floquet engineering for non-equilibrium steady states with gradient-based methods
Alberto Castro, Shunsuke A. Sato
Non-equilibrium steady states are created when a periodically driven quantum system is also incoherently interacting with an environment -- as it is the case in most realistic situ…
Size-controlled quantum dots reveal the impact of intraband transitions on high-order harmonic generation in solids
Kotaro Nakagawa, Hideki Hirori, Shunsuke A. Sato +7
Since the discovery of high-order harmonic generation (HHG) in solids, much effort has been devoted to understanding its generation mechanism and both interband and intraband trans…
Ultrafast electron localization and screening in a transition metal dichalcogenide
Z. Schumacher, S. A. Sato, S. Neb +4
The coupling of light to electrical charge carriers in semiconductors is the foundation of many technological applications. Attosecond transient absorption spectroscopy measures si…
