SUMMARY:Anderson Localization: looking forward\, Physics Department Co
 lloquium\, Boris Altshuler\, Columbia University
DESCRIPTION:Localization of the eigenfunctions of quantum particles in
  a random potential was discovered by P.W. Anderson more than 50 years
  ago. In spite of its respectable age and rather intensive theoretical
  and experimental studies this field is by far not exhausted. Anderson
  localization was originally discovered and studied in connection with
  spin relaxation and charge transport in disordered conductors. Later 
 this phenomenon was observed for light\, microwaves\, sound\, and more
  recently for cold atoms. Moreover\, it became clear that the domain o
 f applicability of the concept of localization is much broader. For ex
 ample\, it provides an adequate framework for discussing the transitio
 n between integrable and chaotic behavior in quantum systems. This tal
 k is an introduction into the current understanding of the Anderson lo
 calization and its manifestation in different systems. In particular\,
  we will see that the ideas developed for understanding quantum mechan
 ics of a single particle can be extended to attack many-body problems 
 in the presence of disorder.
