Classical QGP : III. The free energy

Understand

We explore further the classical QGP using methods from classical liquids.

• The partition function of an ensemble of SU(N_c) colored charge spheres is constructed.
• We analyze it using a cumulant expansion (low density) and a loop expansion (high temperature) after resumming the Debye screening effects.
• The pertinent free energies are derived in both limits and compared to recent molecular dynamics results.
