Investigating transport properties of chiral p-wave superconductors

Chiral p-wave superconductors are systems that might host Majorana fermions. One of the key telltale signs of Majorana bound states (MBS) is a metal-insulator transition when disorder is introduced in the host material. For example, quasiparticle localization by a space-dependent random mass M(r) with a variation on the scale of lattice constant results in a metal-insulator transition. On the other hand, a randomly varying electrostatic potential V(r) can create a random arrangement of MBS through the Shockley mechanism. In this numerical study, we investigate the combined effect of the disorders, the random mass and random local potential, on the transport of chiral p-wave superconductors.
