Scaling and diffusion of Dirac composite fermions
We study the effects of quenched disorder and a dissipative Coulomb interaction on an anyon gas in a periodic potential undergoing a quantum phase transition. We use a (2+1)-dimensional low-energy effective description that involves N_{f}=1 Dirac fermion coupled to a U(1) Chern-Simons gauge field at...
