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…

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

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
