States of matter corresponding to energy of 1011 J/m3 or equivalently pressures of 1 Mbar and above, are classified as High-Energy-Density (HED) states. The importance of this subject is underscored by the fact that it spans over very wide areas of basic and applied physics (e.g., astrophysics, planetary sciences, geophysics, plasma physics, fluid dynamics, radiation hydrodynamics, magnetohydrodynamics, material sciences, condensed matter physics, interaction of intense radiation with matter, atomic and molecular physics and many others). In addition, this field has great potential for numerous very important industrial applications. A study of fundamental properties of HED matter is therefore of considerable scientific importance as well as of great technological interest.
