Nonergodic Phases in Strongly Disordered Random Regular Graphs
Nonergodic Phases in Strongly Disordered Random Regular Graphs
We combine numerical diagonalization with a semi-analytical calculations to prove the existence of the intermediate non-ergodic but delocalized phase in the Anderson model on disordered hierarchical lattices. We suggest a new generalized population dynamics that is able to detect the violation of ergodicity of the delocalized states within the Abou-Chakra, …
