| contents | Recent introduction of center vortices with 't Hooft flux on two torus compactification leads to a new semiclassical regime where confinement is analytically calculable. In this work, we investigate the stability of the classical minima for gauge fields under quantum corrections. Although the classical $Z_N \times Z_N$ symmetric minima is stable at small-$N$, because of the nature of the quantum corrections, it can be destabilized at sufficiently large-$N$. Using Morita equivalence, we switch to field theory on noncommutative torus instead of working with theory on torus with 't Hooft flux in a certain limit. Noncommutative Yang-Mills theory compactified on two torus leads to a tachyonic instability and it leads to the spontaneous breaking of translation symmetry. We discuss that spontaneous breaking of translation symmetry is identical to the $Z_N \times Z_N$ center symmetry breaking similar to an older version of large N twisted Eguichi-Kawai model. We compute the photon polarization diagram for noncommutative U(1) theory in the presence of adjoint fermions and show that they stabilize the tachyonic instability on the noncommutative torus and restore the broken symmetry. |
