DESCRIPTION:Speakers: Volodymyr (Vova) Riabov (Institute of Science and Te
 chnology Austria)\n\nRandom band matrices have entries concentrated in a n
 arrow band of widthW around the main diagonal\, modeling systems with spat
 ially localized in-teractions. We consider one-dimensional random band mat
 rices with band-width W ≫ N 1/2\, general variance profile\, and arbitra
 ry entry distributions.We establish complete isotropic delocalization\, qu
 antum unique ergodicity(eigenstate thermalization)\, and Wigner-Dyson univ
 ersality in the bulk of thespectrum. The key technical input is a family o
 f local laws capturing the spa-tial decay of resolvent entries\, establish
 ed using a combination of Ornstein-Uhlenbeck dynamics and Green function c
 omparison (the Zigzag strategy).Based on joint work with  Laszló Erdős.
