DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/21/">H
 ydrodynamics and the Spectral Form Factor</a>\nby Brian Swingle (MIT) as p
 art of NHETC Seminar\n\n\nAbstract\nEnsembles of quantum chaotic systems a
 re expected to exhibit random matrix universality in their energy spectrum
 . The presence of this universality can be diagnosed by looking for a line
 ar in time 'ramp' in the spectral form factor\, but for realistic systems 
 this feature is typically only visible after a sufficiently long time. It 
 is important to understand the emergence of this universality and how it c
 onnects to the larger body of phenomena associated with quantum chaos. Thi
 s talk will present a hydrodynamic theory of the spectral form factor in s
 ystems with slow modes. The formalism predicts the linear ramp at sufficie
 ntly late time and gives a quantitative framework for computing the approa
 ch to ramp.\n
