Self Consistency

We use a Hamiltonian formalism to analyse the self-consistent wave–particle dynamical interaction involving magnetized electrons and ordinarily polarized electromagnetic waves. Considering first-harmonic cyclotron resonances, we show that there is a critical value of the electronic average density. For systems with lower than critical densities the saturation process is dictated by relativistic detuning effects, and wave dynamics may be disregarded. However, for systems with larger densities, saturation is governed by the available electromagnetic free energy, and the wave dynamics turns out to be essential.

Simple Systems

A parametrized perturbation scheme is derived for simple systems with purely repulsive forces. The parameter is chosen so that the pressure in the system found by differentiating the free energy is consistent with that found by integrating over the radial distribution function. Results of calculations for the equation of state of an inverse-12 fluid are presented and found to be in excellent agreement with Monte Carlo simulations. The use of the results of the self-consistent scheme as a reference system for the Lennard-Jones fluid is discussed.

Quark Number Susceptibility

We study the thermodynamic geometry arising from the free energy for the two- and three-flavor finite temperature hot QCD near the critical temperature. We develop a geometric notion for QCD thermodynamics, relating it with the existing microscopic quantities, e.g. quark-number susceptibility, which appears naturally within an approximately self-consistent resummation of perturbative QCD. We further incorporate thermal fluctuations in the free energy, thus yielding the geometric properties of local and global chemical correlations. These investigations are perturbative in nature. Nevertheless, one could apply the same line of thought for the geometric realization of underlying quark susceptibilities, either in the fabric of lattice QCD or in that of nonperturbative QCD.
