Title: Properties of confining gauge field configurations in the pseudoparticle approach

Abstract

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 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 known Euclidean Yang-Mills pseudoparticle solutions with Pontryagin index n are parametrized by 5n constants describing the size and location of each pseudoparticle. By insisting on conformal covariance of the solutions, we show that more general solutions exist: they are parametrized by 5n + 4 constants. We further demonstrate that the additional degrees of freedom are not gauge artifacts and correspond to a new degeneracy of pseudoparticle configurations.
  • The quantum field theory built upon the SU(2) Yang-Mills pseudoparticle solution is studied in an O(5) covariant formalism. The gauge ghost and small oscillations of the Yang-Mills field problems are analyzed completely on the O(5) hypersphere, and it is shown that solutions of the various eigenvalue equations may be easily projected back into Euclidean space. Zero-frequency modes in the small oscillations are found, and their interpretation is given within the framework of the O(5,1) conformal group. (AIP)
  • We address the problem of determining the type I, type II or borderline dual superconductor behavior in maximal Abelian gauge SU(2) through the study of the dual Abrikosov vortex. We find that significant electric currents in the simulation data call into question the use of the dual Ginzburg-Landau Higgs model in interpreting the data. Further, two definitions of the penetration depth parameter take two different values. The splitting of this parameter into two is intricately connected to the existence of electric currents. It is important in our approach that we employ definitions of flux and electric and magnetic currents thatmore » respect Maxwell equations exactly for lattice averages independent of lattice spacings. Applied to specific Wilson loop sizes, our conclusions differ from those that use the dual GLH model.« less
  • 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
