Computation of topological phase diagram of disordered Pb_{1−x}Sn_{x}Te using the kernel polynomial method

We present an algorithm to determine topological invariants of inhomogeneous systems, such as alloys, disordered crystals, or amorphous systems. Based on the kernel polynomial method, our algorithm allows us to study samples with more than 10^{7} degrees of freedom. Our method enables the study of l...
