A smoother approach to scaling by suppressing monopoles and vortices
نویسنده
چکیده
Suppressing monopoles and vortices by introducing large chemical potentials for them in the Wilson action for the SU(2) lattice gauge theory, we study the nature of the deconfinement phase transition on N σ ×Nτ lattices for Nτ =4, 5, 6 and 8 and Nσ = 8–16. Using finite size scaling theory, we obtain ω ≡ γ/ν = 1.93 ± 0.03 for Nτ = 4, in excellent agreement with universality. The critical couplings for Nτ = 4, 5, 6 and 8 lattices exhibit large shifts towards the strong coupling region when compared with the usual Wilson action, and suggest a lot smoother approach to scaling.

متن کاملImpact of Z2 monopoles and vortices on the deconfinement transition
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 ...

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...

Two kinds of topological defects were proposed by ’t Hooft as possible configurations condensing in the disordered phase of SU(N) Yang-Mills theories to produce confinement: ZN vortices [1] and monopoles [2]. Monopoles have the natural topology to three dimensional space, corresponding to a mapping: S2 → SU(2). Their condensation implies dual superconductivity of the vacuum, and gives an appeal...
