What is High-Energy-Density Physics (HEDP)/Warm Dense Matter (WDM)?

Plasma and Ultrafast Physics Group

HEDP: Studying physics at very very high pressures (P > 1011 – 1015 Pa!)

Why do we care about HEDP and WDM?

  • We care about them because they widely exist in nature:

  • We care about them because they can now be created in laboratories:

  • We care about them because they are routinely encountered in inertial confinement fusion (ICF) and HED experiments:

  • Finally, we care about them because we do not fully understand the properties of matter at such exotic conditions:
    • the classical plasma theory breaks down because it's too cold!
    • the traditional condense-matter theory fails because it's too hot!
    • strong-coupling and quantum degeneracy effects play crucial roles!!
