SUMMARY:Localisation for random block operators - Müller\, P (Ludwig-Maxi
 milians-Universitt Mnchen)

DESCRIPTION:We study spectral properties of random block operators that ar
 e common in the physical modelling of mesoscopic disordered systems such a
 s dirty superconductors. Our results include ergodic properties\, the loca
 tion of the spectrum\, existence and regularity of the integrated density 
 of states (Wegner estimate)\, Lifshits tails and dynamical localisation in
  a neighbourhood of the internal band edges. Special attention is paid to 
 the peculiarities arising from the block structure. Technically\, one has 
 to cope with a non-monotone dependence on the random couplings.
