DESCRIPTION:Title: <a href="https://researchseminars.org/talk/USC-HET/16/"
 >Higher-dimensional origin of extended black hole thermodynamics</a>\nby A
 ndrew Svesko (UCL (UK)) as part of USC High Energy Theory Seminars\n\nLect
 ure held in Zoom. (Normally) SSC 319 on University Park Campus (USC).\n\nA
 bstract\nA key difference between black holes and ordinary thermal systems
  is the absence of a pressure-volume work term in the first law of black h
 ole thermodynamics. It is possible to introduce such a work term for black
  holes in backgrounds with a cosmological constant by treating the cosmolo
 gical constant as a pressure\,offering a rich gravitational perspective on
  everyday phenomena.  Missing\, however\, is justification for allowing va
 riations of the cosmological constant. In this talk I will present a highe
 r-dimensional origin of 'extended black hole thermodynamics' using hologra
 phic braneworlds. In this set-up\, gravity is coupled to a lower-dimension
 al membrane such that classical black holes in a bulk anti-de Sitter space
 time correspond to exact quantum corrected black holes localized on the br
 ane\, including all orders of semi-classical backreaction.  Crucially\, va
 rying the tension of the brane leads to a dynamical cosmological constant 
 on the brane\, and\, correspondingly\, a variable pressure attributed to t
 he brane black hole. In other words\, standard thermodynamics of classical
  black holes induces extended thermodynamics of quantum black holes on a b
 rane. As proof of concept\, I will present the extended thermodynamics of 
 the quantum BTZ black hole\, also providing a microscopic interpretation u
 sing `double holography’.\n
