Spinodal decomposition in high temperature gauge theories

Spinodal decomposition in pure-gauge QCD

Spinodal decomposition in a model of pure-gauge SU(2) theory that incorporates a deconfinement phase transition is investigated by means of real-time lattice simulations of the fully nonlinear Ginzburg-Landau equation. Results are compared with a Glauber dynamical evolution using Monte Carlo simulations of pure-gauge lattice QCD.

The high temperature phase transition in SU ( N ) gauge theories

We calculate the continuum value of the deconfining temperature in units of the string tension for SU(4), SU(6) and SU(8) gauge theories, and we recalculate its value for SU(2) and SU(3). We find that the N -dependence for 2 ≤ N ≤ 8 is well fitted by Tc/ √ σ = 0.596(4) + 0.453(30)/N, showing a rapid convergence to the large-N limit. We confirm our earlier result that the phase transition is fir...

High Temperature Confinement in SU(N) Gauge Theories

SU(N) gauge theories, extended with adjoint fermions having periodic boundary conditions, are confining at high temperature for sufficiently light fermion mass m. Lattice simulations indicate that this confining region is smoothly connected to the confining region of low-temperature pure SU(N) gauge theory. In the high temperature confining region, the one-loop effective potential for Polyakov ...

The Spatial String Tension in High Temperature Lattice Gauge Theories

We develop some techniques which allow an analytic evaluation of spacelike observables in high temperature lattice gauge theories. We show that such variables are described extremely well by dimensional reduction. In particular, by using results obtained in the context of “Induced QCD”, we evaluate the contributions to space-like observables coming from the Higgs sector of the dimensionally red...
