Stability of LiF Crystal in the Warm Dense Matter State

The finite temperature density functional theory approach is deployed for the description of the fee LiF crystal in a two-temperature warm dense matter state with hot electrons and cold lattice that is formed after ultrafast energy deposition. The lattice stability and the interatomic bonding at elevated electronic temperatures are studied. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA,Weinheim
