Deconfinement transition in the compact 3d U(1) lattice gauge theory at finite temperatures
نویسنده
چکیده
Critical properties of the compact three-dimensional U(1) lattice gauge theory are explored at finite temperatures on an asymmetric lattice. For vanishing value of the spatial gauge coupling one obtains an effective two-dimensional spin model which describes the interaction between Polyakov loops. We study numerically the effective spin model for Nt = 1, 4, 8 on lattices with spatial extension ranging from L = 64 to L = 256. Our results indicate that the finite-temperature U(1) lattice gauge theory belongs to the universality class of the two-dimensional XY model, thus supporting the Svetitsky-Yaffe conjecture. e-mail addresses: [email protected], gravina,[email protected] 1

Phase Structure of a 3D Nonlocal U(1) Gauge Theory: Deconfinement by Gapless Matter Fields
In this paper, we study a 3D compact U(1) lattice gauge theory with a variety of nonlocal interactions that simulates the effects of gapless/gapful matter fields. We restrict the nonlocal interactions among gauge variables only to those along the temporal direction and adjust their coupling constants optimally to simulate the isotropic nonlocal couplings of the original model. This theory is qu...
متن کاملVariational Analysis of Deconfinement in Compact U(1) Gauge Theory
A variational method is used to analyse compact U(1) gauge theory in 2 + 1-dimensions at finite temperature, T , weak coupling, g and where the fundamental magnetic monopoles have magnetic charge 2πn/g. The theory undergoes a critical transition from a confining phase at temperatures below Tc = 2g /nπ to a deconfined phase at temperatures above Tc. The free energy and all its derivatives are co...
متن کاملA cluster algorithm for lattice gauge theories
A new algorithm for simulating compact U(1) lattice gauge theory in three dimensions is presented which is based on global changes in the configuration space. We show that this algorithm provides an effective way to extract partition functions at given external flux. As an application, we study numerically the finite temperature deconfinement phase transition.
متن کاملExternal Fields and Color Confinement
U(1), SU(2), and SU(3) lattice gauge theories in presence of external fields are investigated both in (3+1) and (2+1) dimensions. The free energy of gauge systems has been measured. While the phase transition in compact U(1) is not influenced by the strength of an external constant magnetic field, the deconfinement temperature for SU(2) and SU(3) gauge systems in a constant abelian chromomagnet...
متن کاملFinite-size scaling and deconfinement transition: the case of 4D SU(2) pure gauge theory
A recently introduced method for determining the critical indices of the deconfinement transition in gauge theories, already tested for the case of 3D SU(3) pure gauge theory, is applied here to 4D SU(2) pure gauge theory. The method is inspired by universality and based on the finite size scaling behavior of the expectation value of simple lattice operators, such as the plaquette. We obtain an...
