Quark liberation at high temperature: A Monte Carlo study of SU(2) gauge theory
Quark confinement in a finite-temperature SU(N) gauge theory is formulated as the realization of a global Z/sub N/ symmetry. Spontaneous breakdown corresponds to a transition to a nonconfining,Expand

A Monte Carlo study of SU(2) Yang-Mills theory at finite temperature
Abstract We employ Monte Carlo methods to study SU(2) Yang-Mills theory in the absence of fermions, on a lattice, at finite temperature. We determine the temperature at which a second-orderExpand

Symmetry aspects of finite-temperature confinement transitions
Abstract Analytical and numerical work on confinement phase transitions in finite-temperature Abelian and non-Abelian gauge theories is reviewed. These transitions are order-disorder transitions andExpand

Spectroscopy of SU(4) composite Higgs theory with two distinct fermion representations
We have simulated the SU(4) lattice gauge theory coupled to dynamical fermions in the fundamental and two-index antisymmetric (sextet) representations simultaneously. Such theories arise naturally inExpand

Metastable nonconfining states in SU(3) lattice gauge theory with sextet fermions
We study the SU(3) lattice gauge theory, with two flavors of sextet Wilson-clover fermions, near its finite-temperature phase transition. We find metastable states that have Wilson line expectationExpand

Nonperturbative beta function in three-dimensional electrodynamics
We apply the Schr\"odinger functional method to the Abelian gauge theory in three dimensions with ${N}_{f}=2$ four-component fermions. We find that the calculated beta function does not cross zero inExpand

Quantum electrodynamics on a lattice: A Hamiltonian variational approach to the physics of the weak-coupling region
We develop and apply a Hamiltonian variational approach to the study of quantum electrodynamics formulated on a spatial lattice in both 2 + 1 and 3 + 1 dimensions. Two lattice versions of QED areExpand

First Order Phase Transition in the SU(3) Gauge Theory at Finite Temperature
We argue that the phase transition which separates the low-temperature confining phase from the high-temperature nonconfining phase in the SU(3) gauge theory (without quarks) is first order.

Infrared fixed point in SU(2) gauge theory with adjoint fermions
We apply Schroedinger-functional techniques to the SU(2) lattice gauge theory with N{sub f}=2 flavors of fermions in the adjoint representation. Our use of hypercubic smearing enables us to work atExpand
