The 't Hooft-Veneziano limit of the Polyakov loop models
O. Borisenko, V. Chelnokov, S. Voloshyn
The broad class of U(N) and SU(N) Polyakov loop models on the lattice are solved exactly in the combined large N, Nf limit, where N is a number of colors and Nf is a number of quar…
Finite density 2d O(3) sigma model: dualization and numerical simulations
B. Alles, O. Borisenko, Alessandro Papa
The action of the 2d O(3) non-linear sigma model on the lattice in a bath of particles, when expressed in terms of standard O(3) degrees of freedom, is complex. A reformulation of…
Duals of U(N) LGT with staggered fermions
O. Borisenko, V. Chelnokov, S. Voloshyn
Various approaches to construction of dual formulations of non-abelian lattice gauge theories are reviewed. In the case of U(N) LGT we use a theory of the Weingarten functions to c…
A new approach to the two-dimensional -model with a topological charge
C. Torrero, O. Borisenko, V. Kushnir +2
Based on character decomposition, a dual transformation is introduced leading to two formulations of the theory which should allow for a removal/softening of the sign problem in th…
On a development of the phenomenological renormalization group
O. Borisenko, V. Chelnokov, V. Kushnir
We propose a modification of the Nightingale renormalization group for lattice spin and gauge models by combining it with the cluster decimation approximation. Essential ingredient…

O. Borisenko, V. Chelnokov, G. Cortese +3
We perform a numerical study of the phase transitions in three-dimensional Z(N) lattice gauge theories at finite temperature for N>4. Using the dual formulation of the models and a…
Phase transitions in strongly coupled 3d Z(N) lattice gauge theories at finite temperature
O. Borisenko, V. Chelnokov, G. Cortese +4
We perform an analytical and numerical study of the phase transitions in three-dimensional Z(N) lattice gauge theories at finite temperature for N>4 exploiting equivalence of these…
The phase transitions in 2D Z(N) vector models for N>4
O. Borisenko, V. Chelnokov, G. Cortese +3
We investigate both analytically and numerically the renormalization group equations in 2D Z(N) vector models. The position of the critical points of the two phase transitions for…
Critical behavior of the compact 3d U(1) gauge theory on isotropic lattices
Oleg Borisenko, Roberto Fiore, Mario Gravina +1
We report on the computation of the critical point of the deconfinement phase transition, critical indices and the string tension in the compact three dimensional U(1) lattice gaug…
Critical behavior of the compact 3d U(1) theory in the limit of zero spatial coupling
Oleg Borisenko, Mario Gravina, Alessandro Papa
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 gaug…
Plaquette representation for 3D lattice gauge models: I. Formulation and perturbation theory
O. Borisenko, S. Voloshin, M. Faber
We develop an analytical approach for studying lattice gauge theories within the plaquette representation where the plaquette matrices play the role of the fundamental degrees of f…
Exponential corrections to low-temperature expansion of 2D non-abelian models
O. Borisenko, V. Kushnir
The thermodynamic limit of certain exponential corrections to the weak coupling expansion of two-dimensional models is investigated. The expectation values of operators contributin…
Towards the Deconfinement Phase Transition in Hot Gauge Theories
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. We discuss properties of chromoelectric and…
Triality in QCD at Zero and Finite Temperature: A New Direction
M. Faber, O. Borisenko, G. Zinovjev
Discrete symmetries in grand canonical ensembles and in ensembles canonical with respect to triality are investigated. We speculate about the general phase structure of finite temp…
