Phase space signatures of the Anderson transition
Andre Wobst, Gert-Ludwig Ingold, Peter Hänggi +1
We use the inverse participation ratio based on the Husimi function to perform a phase space analysis of the Anderson model in one, two, and three dimensions. Important features of…
Delocalization and Heisenberg's uncertainty relation
Gert-Ludwig Ingold, Andre Wobst, Christian Aulbach +1
In the one-dimensional Anderson model the eigenstates are localized for arbitrarily small amounts of disorder. In contrast, the Harper model with its quasiperiodic potential shows…
From ballistic motion to localization: a phase space analysis
Andre Wobst, Gert-Ludwig Ingold, Peter Hänggi +1
We introduce phase space concepts to describe quantum states in a disordered system. The merits of an inverse participation ratio defined on the basis of the Husimi function are de…
Disordered Systems in Phase Space
Dietmar Weinmann, Sigmund Kohler, Gert-Ludwig Ingold +1
As a function of the disorder strength in a mesoscopic system, the electron dynamics crosses over from the ballistic through the diffusive towards the localized regime. The ballist…
