We present results on QCD with four dynamical flavors in the temperature range $0.9 \lesssim T/T_c \lesssim 2$. We have performed lattice simulations with Wilson fermions at maximal twist and measured the topological charge with gluonic and fermionic

The Monte Carlo simulation of SU(2) quantum chromodynamics (QCD) with a nonzero chiral chemical potential has been reported. The dependence of the Polyakov line and chiral condensate on the coupling constant and chiral chemical potential has been stu

The phase diagram of two-color QCD with a chiral chemical potential is studied on the lattice. The focus is on the confinement/deconfinement phase transition and the breaking/restoration of chiral symmetry. The simulations are carried out with dynami

In this contribution we present a short overview of the status of non-perturbative investigations of Landau gauge gluon and ghost propagators in Yang-Mills theories with special emphasis on lattice computations in the infrared region.

Two improved superposition schemes for the construction of approximate multi-caloron-anticaloron configurations, using exact single (anti)caloron gauge fields as underlying building blocks, are introduced in this paper. The first improvement deals wi

A semi-classical model is developed to describe pure SU ( 2 ) Yang–Mills gluodynamics at finite temperature as a dilute, non-interacting gas of Kraan–van Baal–Lee–Lu calorons including the case of non-trivial holonomy. Temperature-dependent p

The 2-dimensional U(1) gauge-Higgs model with a topological term is a simple example of a lattice field theory where the complex action problem comes from the topological term. We show that the model can be exactly rewritten in terms of dual variable

We study the topological structure of QCD by cluster analysis. The fermionic topological charge density is constructed from low lying modes of overlap Dirac operator for three types of temporal boundary conditions for fermion field. This gives the po

We study finite (physical) volume and scaling violation effects of the Landau gauge ghost propagator as well as of the running coupling ${\ensuremath{\alpha}}_{s}(p)$ in the $SU(2)$ lattice gauge theory. We consider lattices with physical linear size
