                      `Ergodicity Hypothesis' breakdown in
                         Random Schroedinger Operators
 
Abstract:
Of current research interest in the area concerning the disorder effects on the
dynamics under random Schroedinger operators  is the occurrence of  energy
regimes (phases) in which extended states are formed from  resonating local
quasi-modes.  The corresponding eigenstates are "non-ergodic", in the sense
that they violate a heuristic version of the equidistribution principle, yet
they do not exhibit Anderson localization.  Such phases were proven to occur in
the random Schroedinger  operator on tree graphs (in a joint work with Simone
Warzel), and are also expected to show up in many-particle systems which are
the subject of ongoing work (with SW and Mira Shamis).
