DESCRIPTION:Anomalous Luttinger equivalence between temperature and curved 
 spacetime: From black holes to thermal quenches\nDavid Carpentier (Laborat
 oire de Physique\, ENS Lyon)\n\nOnline seminar.\nRegister in advance for t
 his meeting on zoom:\nhttps://cnrs.zoom.us/meeting/register/tJ0scu2srjwoGN

 on email containing information about joining the meeting.\n\nIn condensed
  matter\, thermal response theory relies on a deep connection\nbetween gra
 vitational fields and thermal transport\, established in 1964 by Luttinger
 \, building on earlier ideas of Tolman and Ehrenfest. Does this connection
  extend beyond pure technical considerations ? In this work\, we revisit t
 he celebrated Tolman-Ehrenfest and Luttinger relations and show how to inc
 orporate anomalous quantum fluctuations that become paramount in a strongl
 y curved spacetime. Our extended correspondence between temperature variat
 ions and curvature of spacetime incorporates new quantum energy scales ass
 ociated with these fluctuations\, captured by the so-called gravitational 
 anomalies of quantum field theories.\nOn one hand we  point out that such 
 anomalous fluctuations naturally occur in the quantum atmosphere of a blac
 k hole. On the other hand\, our extended correspondance  implies that anal
 ogous fluctuations are also observable in thermal conductors in the flat-s
 pace time of a laboratory\,  provided that the local temperature varies st
 rongly. As a consequence\, we establish that the gravitational anomalies m
 anifest themselves naturally in non-linear thermal response of a quantum w
 ire. In addition\, we propose a systematic way to identify thermal analogu
 es of black hole’s anomalous quantum fluctuations associated to gravitat
 ional anomalies. We identify their signatures in propagating energy waves 
 following a thermal quench\, as well as in the energy density of heating F
 loquet states induced by repeated thermal quenches.
