Impact of Z2 monopoles and vortices on the deconfinement transition
نویسندگان
چکیده
Suppressing Z2-monopoles shifts the line of deconfinement transitions in the coupling plane of the SU(2) lattice gauge theory with a mixed Villain form of action but it still continues to behave also like the bulk transition line. Separate deconfinement and bulk phase transitions are found on the same lattice, suggesting the two to be indeed coincident at higher adjoint couplings. Universality is restored when both monopoles and vortices are suppressed.

We investigate the effect of Z2 magnetic monopoles and vortices on the finite temperature deconfinement phase transition in the fundamental adjoint SU(2) lattice gauge theory. In the limit of complete suppression of the Z2 monopoles, the mixed action for the SU(2) theory in its Villain form is shown to be self-dual under the exchange of the fundamental and adjoint couplings. By further suppress...

The effect of Z2 magnetic monopoles and vortices on the finite temperature deconfinement phase transition in the fundamental-adjoint Villain form of SU(2) lattice gauge theory has been investigated. A complete suppression of the Z2 monopoles has been shown to lead to an action for the theory which is self-dual under the exchange of the fundamental and adjoint couplings. By further suppressing t...
متن کاملZ 2 Monopoles , Vortices , and The Deconfinement Transition in Mixed Action SU ( 2 ) Gauge Theory
Adding separate chemical potentials λ and γ for Z2-monopoles and vortices respectively in the Villain form of the mixed fundamental-adjoint action for the SU(2) lattice gauge theory, we investigate their role in the interplay between the deconfinement and bulk phase transitions using Monte Carlo techniques. Setting λ to be nonzero, we find that the line of deconfinement transitions is shifted i...
متن کاملThe Deconfinement Transition in SO(3) Gauge Theory
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 o...
متن کاملErgodic SO(3), monopole condensation and vortex free energy
We study the continuum limit of adjoint SU(2) LGT by means of a suppression term for Z2 monopoles. High barriers for tunnelling among different twist sectors are overcome through parallel tempering. Monopole condensation is used to study the deconfinement transition and the properties of the confined phase. Ergodicity in summing over all twist sectors allows an unbiased measure of the ’t Hooft ...
