DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HoloTube/4/"
 >Pairing instability on Luttinger Surfaces : SYK thermodynamics from a con
 densed matter perspective</a>\nby Chandan Setty (University of Florida) as
  part of HoloTube: Applied holography webinars\n\n\nAbstract\nSuperconduct
 ivity results from an instability of the Fermi surface — contour of pole
 s of the single particle propagator — to an infinitesimally small attrac
 tive inter-particle attraction. In this talk\, I will instead discuss the 
 analogous problem on a model Luttinger Surface — contour of zeros of the
  Green function.   Unlike a Fermi surface\, in the presence of an attracti
 ve potential\, the model exhibits a quantum phase transition from a non-Fe
 rmi liquid to a superconducting state. Crucially\,  pair-fluctuations clos
 e to the transition resemble well-studied models with gravity duals such a
 s SYK. I will discuss implications of this result to microscopic models de
 scribing  Mott physics.\n
