Phys. Rev. Lett. 80, 1389–1392 (1998)Infrared Stable Supersymmetry in Chern-Simons Theories with Matter and Quenched DisorderReceived 23 June 1997; published in the issue dated 16 February 1998 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 infrared limit. We show that, although the presence of disorder forbids any supersymmetry of the bare action, infrared stable supersymmetric fixed points and fixed lines are realized in the disorder-averaged effective theories. © 1998 The American Physical Society URL:
