摘要: The 1D Anderson model possesses a completely localized spectrum of eigenstates for all values the disorder. We consider effect projecting Hamiltonian to truncated Hilbert space, destroying time-reversal symmetry. analyze ensuing using different measures such as inverse participation ratio and sample-averaged moments position operator. In addition, we examine amplitude fluctuations in detail detect possibility multifractal behavior (characteristic mobility edges) that may arise result truncation procedure.
