Finite temperature SU(2) gauge theory: critical coupling and universality class
Alexander Velytsky
We examine SU(2) gauge theory in 3+1 dimensions at finite temperature in the vicinity of critical point. For various lattice sizes in time direction () we extract high…
Fisher's Zeros and Perturbative Series in Gluodynamics
A. Denbleyker, D. Du, Y. Meurice +1
We study the zeros of the partition function in the complex beta plane (Fisher's zeros) in SU(2) and SU(3) gluodynamics. We discuss their effects on the asymptotic behavior of the…
Improved actions and lattice coarsening effects in MCRG studies in SU(2) LGT
E. T. Tomboulis, A. Velytsky
We study decimation procedures and effective (improved) actions in the framework of Monte Carlo Renormalization Group (MCRG). Particular attention is paid to matching the form of t…
Fisher's zeros of quasi-Gaussian densities of states
A. Denbleyker, D. Du, Y. Meurice +1
We discuss apparent paradoxes regarding the location of the zeros of the partition function in the complex plane (Fisher's zeros) of a pure SU(2) lattice gauge theory in 4 dime…
String tension and removal of lattice coarsening effects in Monte Carlo Renormalization Group
E. T. Tomboulis, A. Velytsky
We study the computation of the static quark potential under decimations in the Monte Carlo Renormalization Group (MCRG). Employing a multi-representation plaquette action, we find…
Improving the improved action
E. T. Tomboulis, A. Velytsky
We investigate the construction of improved actions by the Monte Carlo Renormalization Group method in the context of SU(2) gauge theory utilizing different decimation procedures a…
