Effects of non-equilibrium in ultrafast irradiation of matter

Popis výsledku v původním jazyce

Invited paper This proceeding discusses nonequilibrium effects in matter exposed to XUV/X-ray irradiation. When ultrashort, intense XUV/X-ray pulses interact with materials, they trigger a complex sequence of processes, including electronic excitation, nonequilibrium electron kinetics, energy exchange with the atomic system, electronic thermalization, and subsequent atomic dynamics. These effects were investigated using XTANT-3, a hybrid simulation tool that simultaneously models all relevant dynamics. XTANT-3 integrates (a) a Monte Carlo transport method for photon absorption and fast electron kinetics, (b) the Boltzmann equation for nonequilibrium slow electron dynamics, (c) a transferable tight-binding approach for electronic structure evolution and interatomic potential modeling, and (d) molecular dynamics for atomic system response. This approach enables a detailed study of nonequilibrium effects in each subsystem and their interplay with nonthermal damage, where electronic excitation alters the interatomic potential. Methods of quantifying the nonequilibrium in the electronic and atomic subsystems are discussed.
