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…
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…
Renormalization Group Therapy
E. T. Tomboulis, A. Velytsky
We point out a general problem with the procedures commonly used to obtain improved actions from MCRG decimated configurations. Straightforward measurement of the couplings from th…
Vortices and confinement
T. G. Kovács, E. T. Tomboulis
We review recent developments in the vortex picture of confinement. We discuss numerical simulations demonstrating that the entire asymptotic string tension is due to vortex-induce…
