The Deconfinement Transition in SO(3) Gauge Theory
نویسنده
چکیده
The SO(3) lattice gauge theory with a Villain form of action was investigated by Monte Carlo techniques on asymmetric lattices with Nτ = 2 and 4, where Nτ is the number of sites in the temporal extent. Unlike the results for higher Nτ , only one transition of second order was found for Nτ = 2 . An extended action with an irrelevant term to suppress Z2 monopoles enabled us to get a better view of the deconfinement transition as the effects of bulk transition could be suppressed as well. Although the action has no global Z2-symmetry for the SO(3) theory, unlike the SU(2) theory at finite temperature, our study revealed a second order deconfinement transition, with properties similar to the deconfinement transition of SU(2).

Deconfinement inYang-Mills: a conjecture for a general gauge Lie group G
Svetitsky and Yaffe have argued that — if the deconfinement phase transition of a (d+1)-dimensional Yang-Mills theory with gauge group G is second order — it should be in the universality class of a d-dimensional scalar model symmetric under the center C(G) of G. These arguments have been investigated numerically only considering Yang-Mills theory with gauge symmetry in the G = SU(N) branch, wh...
متن کاملOn The Deconfinement Transition in SU(4) Lattice Gauge Theory
The deconfinement transition in SU(4) lattice gauge theory is investigated on N s × Nt lattices for Ns = 8–16 and Nt = 4–8 using a modified Wilson action which is expected to be free of any bulk transitions. The susceptibility χ |L| , where L is the order parameter for deconfinement, is found to increase linearly with spatial volume for Nt = 4, 5, and 6, indicating a first order deconfinement p...

The SO(3) lattice gauge theory is investigated by Monte Carlo techniques on N σ × 2 lattices with Nσ =6, 8, 10, 12, 16 and 24, in order to shed more light on the interplay of the deconfinement and bulk phase transition in this theory. Our results on average action, adjoint Polyakov loop La, and their susceptibilities clearly demonstrate the absence of any first order phase transition of either ...

The phase diagram of SO(3) lattice gauge theory at finite temperature is investigated by Monte Carlo techniques with a view i) to understand the relationship between the deconfinement phase transitions in the SU(2) and SO(3) lattice gauge theories and ii) to resolve the current ambiguity of the nature of the high temperature phases of the latter. Phases with positive and negative adjoint Polyak...

Maximal ’t Hooft loops are studied in SO(3) lattice gauge theory at finite temperature T . Tunneling barriers among twist sectors causing loss of ergodicity for local update algorithms are overcome through parallel tempering, enabling us to measure the vortex free energy F and to identify a deconfinement transition at some β A . The behavior of F below β crit A shows however striking difference...
