Random-Mass Dirac Fermions in an Imaginary Vector Potential: Delocalization Transition and Localization Length
In this paper, one dimensional system of Dirac fermions with a random-varying mass is studied by the transfer-matrix method. We investigate the effects of nonlocal correlation of the spatial-varying Dirac mass on the delocalization transition. In particular, we numerically calculate both the "typical" and "mean" localization lengths as a function …
