Quantum Chromodynamics with Many Flavors [PDF]
, 1998 We investigate the phase structure of lattice QCD for general number of flavors $N_F$. Based on numerical data combined with the results of the perturbation theory we propose the following picture: When $N_F \ge 17$, there is only one IR fixed point at ...

CP-violating theta parameter in the domain model of the QCD vacuum [PDF]
, 2004 A non-zero CP-violating $\theta$ parameter is treated in the domain model which assumes a cluster-like vacuum structure whose units are characterised in particular by a topological charge which is not necessarily an integer number.

Quark Confinement Physics in Quantum Chromodynamics [PDF]
, 1999 We study abelian dominance and monopole condensation for the quark confinement physics using the lattice QCD simulations in the MA gauge. These phenomena are closely related to the dual superconductor picture of the QCD vacuum, and enable us to construct

Monopole density around static color sources [PDF]
, 1994 We analyze the vacuum structure with respect to magnetic monopoles of quenched QCD in the presence of static color sources. Distributions of the monopole density around static quarks and mesons are computed in both phases of QCD. We observe a suppression

SU(N) fractional instantons and the Fibonacci sequence
Journal of High Energy Physics, 2022 We study, by means of numerical methods, new SU(N) self-dual instanton solutions on R × T 3 with fractional topological charge Q = 1/N. They are obtained on a box with twisted boundary conditions with a very particular choice of twist: both the number of

Polyakov Loop Dynamics in the Center Symmetric Phase [PDF]
, 1998 A study of the center symmetric phase of SU(2) Yang Mills theory is presented. Realization of the center symmetry is shown to result from non-perturbative gauge fixing.

Exact Results And Soft Breaking Masses In Supersymmetric Gauge Theory [PDF]
, 1995 We give an explicit formalism connecting softly broken supersymmetric gauge theories (with QCD as one limit) to $N=2$ and $N=1$ supersymmetric theories possessing exact solutions, using spurion fields to embed these models in an enlarged $N=1$ model. The

F4, E6 and G2 exceptional gauge groups in the vacuum domain structure model [PDF]
, 2018 Using vacuum domain structure model, trivial static potentials in various representations of $F_4$, $E_6$ and $G_2$ exceptional groups are calculated by means of the unit center element.

Electromagnetically superconducting phase of QCD vacuum induced by strong magnetic field
, 2010 In this talk we discuss our recent suggestion that the QCD vacuum in a sufficiently strong magnetic field (stronger than 10^{16} Tesla) may undergo a spontaneous transition to an electromagnetically superconducting state.
