Finite temperature phase transition in the 4 d compact U ( 1 ) lattice gauge theory
نویسنده
چکیده
We study the phase diagram of the 4d compact U(1) gauge theory as a function of the number of Euclidean time slices. We use the helicity modulus [1] as order parameter to probe the phase transitions. The order of the transition along the phase boundaries is studied and the possibility of a continuum limit is discussed. We present new, strong evidence that the T = 0 bulk phase transition is first-order. [email protected] [email protected]

Deconfinement transition in the compact 3d U(1) lattice gauge theory at finite temperatures
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 ...

We describe results of a high-statistics finite size scaling analysis of 4d compact U(1) lattice gauge theory with Wilson action at the phase transition point. Using a multicanonical hybrid Monte Carlo algorithm we generate data samples with more than 150 tunneling events between the metastable states of the system, on lattice sizes up to 18 4. We performed a first analysis within the Borgs-Kot...

A study of the phase transition in 4D pure compact U(1) LGT on toroidal and spherical lattices. Abstract We have performed a systematic study of the phase transition in the pure compact U(1) lattice gauge theory in the extended coupling parameter space (β, γ) on toroidal and spherical lattices. The observation of a non-zero latent heat in both topologies for all investigated γ ∈ [+0.2, −0.4], t...
متن کاملCritical exponents for U(1) lattice gauge theory at finite temperature
For compact U(1) lattice gauge theory (LGT) we have performed a finite size scaling analysis on Nτ N3 s lattices for Nτ fixed and Ns → ∞, approaching the phase transition from the confined phase. For Nτ = 4, 5 and 6 our data contradict the expected scenario that this transition is either first order or in the universality class of the 3d XY model. If there are no conceptional flaws in applying ...

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.
