Instability of the disordered critical points of Dirac fermions
Instability of the disordered critical points of Dirac fermions
Recently, in an attempt to study disordered criticality in quantum Hall systems and $d$-wave superconductivity, it was found that two-dimensional random Dirac-fermion systems contain a line of critical points that is connected to the pure system. We use bosonization and current algebra to study properties of the critical line and …
