Title: Classes of confining gauge field configurations

Abstract

We present a numerical method to compute path integrals in effective SU(2) Yang-Mills theories. The basic idea is to approximate the Yang-Mills path integral by summing over all gauge field configurations, which can be represented as a linear superposition of a small number of localized building blocks. With a suitable choice of building blocks many essential features of SU(2) Yang-Mills theory can be reproduced, particularly confinement. The analysis of our results leads to the conclusion that topological charge as well as extended structures are essential elements of confining gauge field configurations.

  • The pseudoparticle approach is a numerical method to approximate path integrals in SU(2) Yang-Mills theory. Path integrals are computed by summing over all gauge field configurations, which can be represented by a linear superposition of a small number of pseudoparticles with amplitudes and color orientations as degrees of freedom. By comparing different pseudoparticle ensembles we determine properties of confining gauge field configurations. Our results indicate the importance of long range interactions between pseudoparticles and of non trivial topological properties.
  • We study a three-dimensional (3D) U(1) gauge theory coupled to a charged Higgs field with a spatially varying mass term. By choosing the mass term to be nonzero outside a 2D plane, an inhomogeneous, spontaneous breaking of the U(1) gauge symmetry confines the gauge fields to the 2D plane. The photon acquires a mass outside this mass defect. On the defect the 3D gauge action is reduced to an effective 2D gauge action. Simulations show the average plaquette on the defect has the required 2D value which demonstrates the above mechanism. We propose this as a way to simulate gaugemore » theories of chiral fermions in conjunction with the method recently proposed by Kaplan.« less
  • We study the response of confining gauge theory to the external electric field by using holographic Yang-Mills theories in the large N{sub c} limit. Although the theories are in the confinement phase, we find a transition from the insulator to the conductor phase when the electric field exceeds its critical value. Then, the baryon number current is generated in the conductor phase. At the same time, in this phase, meson melting is observed through the quasinormal modes of the meson spectrum. Possible ideas are given for the string state corresponding to the melted mesons, and they lead to the ideamore » that the source of this current may be identified with the quarks and antiquarks supplied by the melted mesons. We also discuss other possible carriers. Furthermore, from the analysis of the massless quark, chiral symmetry restoration is observed at the insulator-conductor transition point by studying a confining theory in which the chiral symmetry is broken.« less
  • A parametric representation for the gauge fields invariant under a gauge transformation is presented in the case of the pure {ital SU}(2) gauge field theory. This class of gauge fields constitutes the Gribov horizon on a gauge-fixing surface. A special gauge in (1+2) dimensions is proposed, in which the Gribov horizon is representable in a simple, analytical form, and the Faddeev{endash}Popov determinant is explicitly calculable. A possible new mechanism to generate a non-zero vacuum expectation value for the gauge field strength is suggested. Copyright {copyright} 1996 Academic Press, Inc.
  • Classical SU(3) gauge theory with a static external source is studied numerically for finite-energy non-Coulombic solutions. Spherically symmetric, time-independent solutions are found for a class of sources described by two parameters. We have found a number of solutions that bifurcate at a critical source strength, as well as solutions that end at a critical point. Stability of these solutions is briefly discussed.
