Helicity-engineered nonlinear optical responses in photo-excited topological semimetals
Roshan Kumar Thakur, Prachi Venkat, Amar Bharti +1
Topological materials provide a transformative arena for light-driven control of electronic motion; yet, direct manipulation of electron dynamics on sub-cycle timescale remains a s…
Wavelength dependence of laser-induced excitation dynamics in silicon
Prachi Venkat, Tomohito Otobe
Effect of laser wavelength on the carrier-phonon dynamics and damage threshold of silicon is studied numerically. Laser excitation dynamics in silicon is studied using Three-Temper…
Effect of the interference in overlapped double-pulse irradiation at the silicon surface
T. Otobe, P. Venkat
We studied the excitation process of silicon under an intense double pulse. We employed the three-temperature (electron, hole, and lattice) model (3TM) together with Maxwell's equa…
Three-temperature modeling of laser-induced damage process in silicon
Prachi Venkat, Tomohito Otobe
Laser excitation in silicon from femto- to pico-second time scales is studied. We assume the Three-Temperature Model (3TM) which describes the dynamics of the distinct quasi-temper…
Electron excitation rate in dielectrics under an intense elliptically polarized laser field
Prachi Venkat, Tomohito Otobe
Electron excitation in dielectrics is studied for an elliptically polarized laser field. As the first step, we develop an analytical formula for electron excitation rate under elli…
