Se p 20 01 A Classification of 2 d Random Dirac Fermions
نویسنده
چکیده
We present a detailed classification of random Dirac hamiltonians in two spatial dimensions based on the implementation of discrete symmetries. Our classification is slightly finer than that of random matrices, and contains thirteen classes. We also extend this classification to non-hermitian hamiltonians with and without Dirac structure.

We have computed ensembles of complete spectra of the staggered Dirac operator using four-dimensional SU(2) gauge fields, both in the quenched approximation and with dynamical fermions. To identify universal features in the Dirac spectrum, we compare the lattice data with predictions from chiral random matrix theory for the distribution of the low-lying eigenvalues. Good agreement is found up t...
متن کاملMicroscopic Spectra of Dirac Operators and Finite-Volume Partition Functions
Exact results from random matrix theory are used to systematically analyse the relationship between microscopic Dirac spectra and finite-volume partition functions. Results are presented for the unitary ensemble, and the chiral analogs of the three classical matrix ensembles: unitary, orthogonal and symplectic, all of which describe universality classes of SU(Nc) gauge theories with Nf fermions...

We study the symmetry classes for the random Dirac fermions in 2 dimensions. We consider N f species of fermions, coupled by different types of disorder. We analyse the renormalisation group flow at the order of one loop. At N f large, the disorder distribution flows to an isotropic distribution and the effective action is a sigma model. 1. Introduction Random Dirac fermions in 2 dimensions app...

متن کاملScaling near random criticality in two - dimensional Dirac fermions
Recently the existence of a random critical line in two dimensional Dirac fermions is confirmed. In this paper, we focus on its scaling properties, especially in the critical region. We treat Dirac fermions in two dimensions with two types of randomness, a random site (RS) model and a random hopping (RH) model. The RS model belongs to the usual orthogonal class and all states are localized. For...
