We examine a double trace deformation of SU(N) Yang-Mills theory which, for large N and large volume, is equivalent to unmodified Yang-Mills theory up to O(1/N{sup 2}) corrections. In contrast to the unmodified theory, large N volume independence is valid in the deformed theory down to arbitrarily small volumes. The double trace deformation prevents the spontaneous breaking of center symmetry which would otherwise disrupt large N volume independence in small volumes. For small values of N, if…

Comments on large-N volume independence

We study aspects of the large-N volume independence on $ {\mathbb{R}^3} \times {L^\Gamma } $, where LΓ is a Γ-site lattice for Yang-Mills theory with adjoint Wilson-fermions. We find the critical

Deconfinement in Yang-Mills Theory through Toroidal Compactification

We introduce field theory techniques through which the deconfinement transition of four-dimensional Yang-Mills theory can be moved to a semi-classical domain where it becomes calculable using

Yang-Mills theories with chiral matter at strong coupling

Strong coupling dynamics of Yang-Mills theories with chiral fermion content remained largely elusive despite much effort over the years. In this work, we propose a dynamical framework in which we can

θ -dependence and center symmetry in Yang-Mills theories

We investigate the relation between the realization of center symmetry and the dependence on the topological parameter $\theta$ in $SU(N)$ Yang-Mills theories, exploiting trace deformations as a tool

Adiabatic continuity and confinement in supersymmetric Yang-Mills theory on the lattice

A bstractThis work is a step towards merging the ideas that arise from semi-classical methods in continuum QFT with analytic/numerical lattice field theory. In this context, we consider Yang-Mills

Dimensionally reduced SYM4 at large-N: an intriguing Coulomb approximation

We consider the light-cone (LC) gauge and LC quantization of the dimensional reduction of super Yang Mills theory from four to two dimensions. After integrating out all unphysical degrees of freedom,

Realization of center symmetry in two adjoint flavor large-N Yang-Mills

We report on the results of numerical simulations of SU(N) lattice Yang Mills with two flavors of (light) Wilson fermion in the adjoint representation. We analytically and numerically address the

Volume (in)dependence in Yang-Mills theories

Despite their apparent simplicity, Yang-Mills theories give rise to a rich variety of phenomena. Of particular interest to us is the deep relationship between spacetime and colour degrees of freedom

Spectrum of trace deformed Yang-Mills theories

In this paper we study, by means of numerical simulations, the behaviour of the scalar glueball mass and the ground state of the torelon for the $SU(3)$ trace deformed Yang-Mills theory defined on $

Volume independence in large Nc QCD-like gauge theories

Volume independence in large Nc gauge theories may be viewed as a generalized orbifold equivalence. The reduction to zero volume (or Eguchi-Kawai reduction) is a special case of this equivalence. So

Center-symmetric 1/N expansion

The free energy of U(N) gauge theory is expanded about a center-symmetric topological background configuration with vanishing action and vanishing Polyakov loops. We construct this background for

In)validity of large N orientifold equivalence

It has been argued that the bosonic sectors of supersymmetric SU(N) Yang-Mills theory, and of QCD with a single fermion in the antisymmetric (or symmetric) tensor representation, are equivalent in

Twisted-Eguchi-Kawai model: A reduced model for large-N lattice gauge theory

We study the large-$N$ reduced model recently proposed by the present authors. This model is a modified version of the Eguchi-Kawai model incorporating twisted boundary conditions. It is shown that
