SUMMARY:Planckian dissipation in metals - Sean Hartnoll (University of Cam
 bridge)
DTSTART:20230504T130000Z
DTEND:20230504T140000Z
UID:TALK195220@talks.cam.ac.uk
CONTACT:Jan Behrends
DESCRIPTION:I will review the appearance of the Planckian time tau ~ hbar/
 (kB T) in both conventional and unconventional metals. I will then discuss
  the possibility of a Planckian bound on dissipation from both a quasipart
 icle and a many-body perspective. Planckian quasiparticles can arise natur
 ally from a combination of inelastic scattering and mass renormalization. 
 Many-body dynamics\, on the other hand\, is constrained by the basic times
 cales and length scales of local thermalization. This talk will be loosely
  based on the RMP published last year with Andy Mackenzie.
