Atomistic Modeling of Warm Dense Matter in the Two-Temperature State

Warm dense matter is the state between the heated condensed matter and plasma. The importance of the development of warm dense matter theoretical description is determined by the fact that such conditions may arise in the variety of different scientific and industrial applications. For instance, warm dense matter is formed: in the matter impacted by femto- and picoseconds laser pulses; in nuclear materials at the formation of radiation track, etc. In these phenomena, the initial state of the system is a two-temperature state and the electron temperature may be several orders higher than the ion one. In this work, the attempt of development of the united atomistic model of a warm dense matter is carried out. The special consideration is given to the two-temperature effects and the influence of the electron pressure on the behavior of ions.
