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…
Interaction effects on the conductance peak height statistics in quantum dots
Y. Alhassid, A. Wobst
A random interaction matrix model is used to study the statistics of conductance peak heights in Coulomb blockade quantum dots. When the single-particle dynamics conserves time-rev…
