Abstrakt: We present the results of ab initio molecular dynamics (MD) study of a self-trapped hole (Vk-center) in BaF2 crystals. The calculations are performed using the density functional theory in the DFT + U approximation. The configuration of the Vk-center and its possible mechanisms of diffusion throughout the crystal are determined within MD with temperature linearly increasing from 70 to 600 K.
