Phase Space Description of Localization in Disordered One-Dimensional Systems

摘要: The degree of electronic localization in disordered one-dimensional systems is discussed. model simplified to a set Dirac δ-like functions used for the potential Schrodinger equation and calculations are carried out ground state. disorder topological character introduced by random shifts peaks. For comparison, we also discuss two aperiodic peaks: Thue–Morse Fibonacci sequences. localization, both momentum real space, analyzed different strengths sizes system. We calculate length, additionally express effects terms inverse participation function means Husimi quasi-classical distribution phase space electron (position, momentum) coordinate present influence generated sequences on energy spectrum.
