The excited states of the warm dense matter (WDM) are considered. The main attention is paid to the so called structured warm dense matter (SWDM). The SWDM has partly (or fully) ionized plasma properties as well as crystal ones. The methods for WDM creation is described shortly. We give situations where SWDM demonstrates crystal or plasma features. The finite temperature density functional theory approach is deployed for description of the fcc 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. The methods of molecular dynamics and collisional‐radiative kinetics are used to investigate the plasma properties of WDM (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
