Infra-Red Stable Supersymmetry in Chern-Simons Theories with Matter and Quenched Disorder
arXiv:hep-th/9710083 · doi:10.1103/PhysRevLett.80.1389
Abstract
We study Abelian Chern-Simons field theories with matter fields and global SU(N) symmetry in the presence of random weak quenched disorder. In the absence of disorder these theories possess N=2 supersymmetric fixed points and N=1 supersymmetric fixed lines in the infra-red limit. We show that although the presence of disorder forbids any supersymmetry of the bare action, infra-red stable supersymmetric fixed points and fixed lines are realized in the disorder-averaged effective theories.
