SUMMARY:LPTMS Seminar: John Chalker - Salle des séminaires du FAST et du L
 PTMS\, bâtiment Pascal n°530 - 13 Oct 26 11:00
DESCRIPTION:Chaotic many-body quantum dynamics\, spectral correlations\, an
 d energy diffusion\nJohn Chalker (Oxford University)\n&nbsp\;\nI will desc
 ribe a study of chaotic many-body quantum dynamics in a minimal model with
  spatial structure and local interactions. It has a time-independent Hami
 ltonian\, in contrast to quantum circuits and Brownian models\, and is sim
 ple at the single-site level\, in contrast to Sachdev-Ye-Kitaev chains. It
  is analytically tractable for large local Hilbert space dimension and wea
 k intersite coupling. In this limit we show that energy dynamics is descri
 bed by a classical master equation and is diffusive. We also show that the
  spectral form factor can be expressed exactly in terms of the solution to
  this master equation.\n\nJoint work with Dominik Hahn\, Phys. Rev. X 16\
