Warm Dense Matter (WDM) occupies a loosely defined region of phase
space intermediate between solid, liquid, gas, and plasma, and
typically shares characteristics of two or more of these phases.
WDM is generally associated with the combination of strongly
coupled ions and moderately degenerate electrons, and careful
attention to quantum physics and electronic structure is essential.
The lack of a small perturbation parameter greatly limits
approximate attempts at its accurate description. Since WDM resides
at the intersection of solid state and high energy density physics,
many high energy density physics (HEDP) experiments pass through
this difficult region of phase space. Thus, understanding and
modeling WDM is key to the success of experiments on diverse
facilities. These include the National Ignition Campaign centered
on the National Ignition Facility (NIF), pulsed-power driven
experiments on the Z machine, ion-beam-driven WDM experiments on
the NDCX-II, and fundamental WDM research at the Linear Coherent
Light Source (LCLS). Warm Dense Matter is also ubiquitous in
planetary science and astrophysics, particularly with respect to
unresolved questions concerning the structure and age of the gas
giants, the nature of exosolar planets, and the cosmochronology of
white dwarf stars. In this book we explore established and
promising approaches to the modeling of WDM, foundational issues
concerning the correct theoretical description of WDM, and the
challenging practical issues of numerically modeling strongly
coupled systems with many degrees of freedom.
