Variant actions and phase structure in lattice gauge theory

Physical Review D, 1981
We study a simple generalization of Wilson's SU(2) lattice gauge theory. In various limits the model reduces to the usual SU(2), SO(3), or ${Z}_{2}$ models. Using Monte Carlo techniques on a four-dimensional lattice, we follow the known SO(3) and ${Z}_{2}$ first-order transitions into the phase diagram.

Lattice gauge theory and the structure of the vacuum and hadrons

2008
As indicated at the outset, these lectures could only provide an elementary introduction to lattice QCD and an extremely limited survey of results. With this introduction you are now prepared to undertake the much more detailed treatments in the books by Creutz [2], Rothe [4], and Montvay and Munster [3]. I hope these lectures will enable all of you to

Phase structure of strongly coupled lattice Yukawa theories

Nuclear Physics B - Proceedings Supplements, 1992
Abstract Using weak and strong Yukawa coupling expansions combined with the mean field theory, we determine the phase structure of Yukawa models with Z (2), U (1), O (4) scalars. We have taken into account all the terms in the relevant expansions up to eighth order.

Lattice structure of the gluon field condensate in a theory with the Chern-Simons mass

Physical Review D, 1994
In two-dimensional SU(2) gluodynamics with the Chern-Simons mass a ground state in a magnetic field is derived. This vacuum is found to be the lattice of the new type formed from periodic magnetic and electric fields which corresponds to Abrikosov's lattice in superconductivity. It is realized uniquely due to the mass presence.

Lattice-ordered Permutation Groups: The Structure Theory

1996
This survey of lattice-ordered permutation groups focuses especially on their structure theory and on their relation to unordered infinite permutation groups. However, the survey is essentially self-contained. The reader will need only a little familiarity with unordered permutation groups, and none at all with lattice-ordered groups.

Lattice-Dynamical Theory of Structural Phase Transition in Quartz

Journal of the Physical Society of Japan, 1974
A lattice dynamical theory is developed for the phase transition in quartz, and the behaviours of various quantities in the vicinity of the transition temperature are discussed. At temperatures well away from the transition, these behaviours can be interpreted within the framework of the Landau theory. However, drastic deviations from the theory appear

Ginzburg-Landau theory of vortex lattice structure in deformable anisotropic superconductors

Physical Review B, 1995
Correlation between the crystal lattice and the vortex lattice in anisotropic (uniaxial) type-II superconductors due to magnetoelastic interactions is studied theoretically. Within the strain-dependent Ginzburg-Landau model, the energy of the magnetoelastic interaction of the vortex lattice is evaluated with the \ensuremath{\Delta}V effect (difference ...

Role of lattice structure on the Lindemann fusion theory of metals

Journal of Physics F: Metal Physics, 1982
A simple atomistic model for the fusion process of metals is derived from a combination of the atomic model of the lattices and the simple theory of harmonic vibration of the atoms of A1 (FCC), A2 (BCC) and A3 (HCP) type crystals. The lattice factors Lj of these metals and a new physical quantity rho j identical to Lj delta j= alpha /Lj with j=1, 2 and

Phase structure of non-Abelian lattice gauge theories

Physical Review D, 1980
The phase structure of four-dimensional lattice gauge theories based on finite non-Abelian groups is studied by Monte Carlo computations. All models examined exhibit a two-phase structure with a first-order phase transition. In three systems where the gauge group is a discrete subgroup of SU(2) the critical temperature moves toward zero as the order of
