Probing boundary criticality of the 2D random transverse field ising model Tenkila, Gaurav Somashekar


We use the real space renormalization group to numerically analyze the 2D Random Ising Model for a system with a boundary. We detect the critical points by studying the cluster percolations and the spontaneous magnetization at the end of the numerical decimation procedure. We use this to derive the phase diagram for the model depicting the different boundary criticality classes of the theory.
