2d random Dirac fermions: large N approach
Serban, D.
Original · EN
We study the symmetry classes for the random Dirac fermions in 2 dimensions. We consider Nf species of fermions, coupled by different types of disorder. We analyse the renormalisation group flow at the order of one loop. At Nf large, the disorder distribution flows to an isotropic distribution and the effective action is a sigma model.
