DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HET/20/">Hyd
 rodynamics and the Spectral Form Factor</a>\nby Brian Swingle as part of P
 urdue HET\n\n\nAbstract\nEnsembles of quantum chaotic systems are expected
  to exhibit random matrix universality in their energy spectrum. The prese
 nce of this universality can be diagnosed by looking for a linear in time 
 'ramp' in the spectral form factor\, but for realistic systems this featur
 e is typically only visible after a sufficiently long time. It is importan
 t to understand the emergence of this universality and how it connects to 
 the larger body of phenomena associated with quantum chaos. This talk will
  present a hydrodynamic theory of the spectral form factor in systems with
  slow modes. The formalism predicts the linear ramp at sufficiently late t
 ime and gives a quantitative framework for computing the approach to ramp.
