Abstract In this paper we study the interactions among a static quark-antiquark pair in the presence of dense two-color quark matter with lattice simulation. To this end we compute Polyakov line correlation functions and determine the renormalized co

Abstract In this paper we study the confinement/deconfinement transition in lattice SU(2) QCD at finite quark density and zero temperature. The simulations are performed on an 324 lattice with rooted staggered fermions at a lattice spacing a = 0.044

Abstract In this paper we study the SU(3)-gluodynamics shear viscosity temperature dependence on the lattice. To do so, we measure the correlation functions of the energy-momentum tensor in the range of temperatures T /T c ∈ [0.9, 1.5]. To extract

The effect of rotation on the confinement/deconfinement phase transition in SU(3) gluodynamics has been studied in lattice simulation in the rotating reference frame, where rotation is specified by an external gravitational field. To analyze the conf

This paper is devoted to the study of QCD properties under extreme conditions which is carried out within lattice simulations. In particular, the QCD phase diagram in external magnetic field and nonzero baryonic density is studied. In addition, the e

The lattice simulation study of quantum chromodynamics with a nonzero isospin density has been performed. The nonzero isospin density has been introduced by means of the isospin chemical potential μI. The simulation has been performed with dynamic u

In this paper we study how dynamical chiral symmetry breaking is affected by nonzero chiral chemical potential in Dirac semimetals. To perform this study we applied lattice quantum Monte Carlo simulations of Dirac semimetals. Within lattice simulatio

The transverse and longitudinal gluon propagators in the Landau gauge are studied in the two-color lattice QCD at nonzero quark chemical potential $\mu_q$. Parameterization of the momentum dependence of the propagators is provided for all values of c

In this paper we study thermodynamic properties of dense cold $SU(2)$ QCD within lattice simulation with dynamical rooted staggered quarks which in the continuum limit correspond to $N_f=2$ quark flavours. We calculate baryon density, renormalized ch
