Analytical study of low temperature phase of 3D LGT in the plaquette formulation
O. Borisenko, S. Voloshin, M. Faber
We develop an analytical approach for non-abelian gauge models within the plaquette representation where the plaquette matrices play the role of the fundamental degrees of freedom.…
Running Coupling in the SU(2) Lattice Gauge Theory
O. Borisenko, M. Gorenstein, A. Kostyuk
Scenario according to which the SU(2)-gluodynamics is a theory with a nontrivial fixed point is analyzed from the point of view of the modern Monte-Carlo (MC) lattice data. It is f…
On the Deconfinement Phase Transition in Hot Gauge Theories with Dynamical Matter Fields
O. Borisenko, M. Faber, G. Zinovjev
The phase structure of hot gauge theories with dynamical matter fields is reexamined in the canonical ensemble with respect to triality. Since this ensemble implies a projection to…
Domain walls, charge and condensate: a canonical ensemble study
O. Borisenko, M. Faber, G. Zinovjev +1
The deconfinement phase transition is studied in the ensemble canonical with respect to triality. Since this ensemble implies a projection to the zero triality sector of the theory…
Phase structure and confinement properties of noncompact gauge theories II. Z(N) Wilson loop and effective noncompact model
O. A. Borisenko, V. K. Petrov, G. M. Zinovjev +1
An approach to studying lattice gauge models in the weak coupling region is proposed. Conceptually, it is based on the crucial role of the original Z(N) symmetry and the invariant…
Phase structure and confinement properties of noncompact gauge theories I
O. A. Borisenko, V. K. Petrov, G. M. Zinovjev +1
In the context of reviewing noncompact lattice gauge models at zero and finite temperature we study in detail a contribution of the invariant measure and the time-like plaquette co…
