Approximated seventh order calculation of vacuum wave function of 2+1 dimensional SU(2) lattice gauge theory

Using the coupled cluster expansion with the random phase approximation, we calculate the long wavelength vacuum wave function and the vacuum energy of 2+1 dimensional Hamiltonian SU(2) lattice gauge theory (LGT) up to the seventh order. The coefficients μ0 , μ2 of the vacuum wave function show good scaling behavior and convergence in high order calculations. PACS indices: 11.15.Ha, 12.38.Gc

Savvidy "ferromagnetic vacuum" in three-dimensional lattice gauge theory.

The vacuum effective potential of three-dimensional SU(2) lattice gauge theory in an applied color-magnetic field is computed over a wide range of field strengths. The background field is induced by an external current, as in continuum field theory. Scaling and finite volume effects are analyzed systematically. The first evidence from lattice simulations is obtained of the existence of a nontri...

Wave Functions for SU(2) Hamiltonian Lattice Gauge Theory

We study four dimensional SU(2) lattice gauge theory in the Hamiltonian formalism by Green’s Function Monte Carlo methods. A trial ground state wave function is introduced to improve the configuration sampling and we discuss the interplay between its complexity and the simulation systematic errors. As a case study, we compare the leading strong coupling approximation and an improved 4 parameter...

Monopole Order Parameter in Su (2) Lattice Gauge Theory *

We present the results of the numerical calculation of the probability distribution of the value of the monopole creation operator in SU (2) lattice gluodynamics. We work in the maximal abelian projection. It occurs that at the low temperature, below the deconfinement phase transition the maximum of the distribution is shifted from zero, which means that the effective constraint potential is of...

Lattice Gauge Theory

Supercomputers have recently become a crucial tool for the quantum field the-orist. Applied to the formalism of lattice gauge theory, numerical simulations are providing fundamental quantitative information about the interactions of quarks, the fundamental constituents of those particles which experience nuclear interactions. Perhaps most strikingly, these simulations have provided convincing e...
