Light-matter interaction

One of the grand challenges of physics of condensed matter is the characterization and the control of out-of-equilibrium properties of solid materials. Our research is focused on the development of theoretical tools and computational codes for investigation of the electronic response of solids to external pulsed coherent radiation in different regimes of photon energy, pulse energy and pulse duration. The approaches allow for the description of the mechanisms of generation and relaxation of the dense transient electron hole plasma via incoherent collisional effects due to electron-electron and electron-phonon binary encounters. Present research activities are aimed at fully incorporating the change of optical properties in the solid and the pulse propagation in the non-linear photo-excited medium as well as the subsequent modification of the materials such as nonthermal phase transitions, ablation, plasmonics and nanostructuring.
