Universality in Two Dimensional Gauge Theory
We discuss two dimensional Yang – Mills theories with massless fermions in arbitrary representations of a gauge group G. It is shown that the physics (spectrum and interactions) of the massive states in such models is independent of the detailed structure of the model, and only depends on the gauge group G and an integer k measuring the total anomaly. The massless physics, which does depend on ...
متن کاملTwo-Dimensional Gravity and Nonlinear Gauge Theory
We construct a gauge theory based on nonlinear Lie algebras, which is an extension of the usual gauge theory based on Lie algebras. It is a new approach to generalization of the gauge theory. The two-dimensional gravity is derived from nonlinear Poincaré algebra, which is the new Yang-Mills like formulation of the gravitational theory. As typical examples, we investigate R2 gravity with dynamic...
متن کاملUniversality of the gauge-ball spectrum of the four-dimensional pure U(1) gauge theory
We continue numerical studies of the spectrum of the pure U(1) lattice gauge theory in the confinement phase, initiated in [1]. Using the extended Wilson action S = −∑P [β cos(ΘP ) + γ cos(2ΘP )] we address the question of universality of the phase transition line in the (β, γ) plane between the confinement and the Coulomb phases. Our present results at γ = −0.5 for the gauge-ball spectrum are ...
متن کاملThe stability of vacua in two-dimensional gauge theory
We discuss the stability of vacua in two-dimensional gauge theory for any simple, simply connected gauge group. Making use of the representation of a vacuum in terms of a Wilson line at infinity, we determine which vacua are stable against pair production of heavy matter in the adjoint of the gauge group. By calculating correlators of Wilson loops, we reduce the problem to a problem in represen...
متن کاملChern-Simons gauge field theory of two-dimensional ferromagnets.
A Chern-Simons gauged Nonlinear Schrödinger Equation is derived from the continuous Heisenberg model in 2+1 dimensions. The corresponding planar magnets can be analyzed whithin the anyon theory. Thus, we show that static magnetic vortices correspond to the self-dual Chern Simons solitons and are described by the Liouville equation. The related magnetic topological charge is associated with the ...
