Disorder, in the form of impurities and defects, is a common feature of modern quantum materials. In fact, disorder, can be used to change the properties of modern materials. For example, disorder-induced Anderson localization, can control the conducting properties of a system. I.e., by changing the amount of impurities in the material, one can turn the conductor into an insulator. In our research, we have conducted a systematic numerical study of how to study such electron localization and the metal-insulator transition in a three-dimensional Anderson model for two different kinds of disorder, the box, and binary disorder. We have used the quantum cluster typical medium theory to determine the critical values of disorder needed to make the phase transition to occur.
