DESCRIPTION:Title: <a href="https://researchseminars.org/talk/USC-HET/14/"
 >3D Gravity in a Box</a>\nby Ruben Monten (UCLA) as part of USC High Energ
 y Theory Seminars\n\nLecture held in Zoom. (Normally) SSC 319 on Universit
 y Park Campus (USC).\n\nAbstract\nKnown gravitational theories only have a
 symptotic boundary observables. To calculate more local quantities — and
  also to implement the conjectured holographic interpretation of the TTbar
  deformation — one can consider pure three-dimensional gravity on spacet
 imes with a boundary of finite size. I will describe how the covariant pha
 se space framework can be used to calculate the Poisson bracket algebra of
  boundary observables. It is then possible to quantize this system\, takin
 g inspiration from the coadjoint orbit formalism. Working perturbatively i
 n the large c expansion\, we obtain the deformed Alekseev–Shatashvili sy
 mplectic form and action\, as well as the energy spectrum which is consist
 ent with the TTbar prediction up to order 1/√c.\n\nYou will enter a wait
 ing room for a short while. Please use your real name in your zoom session
  so that we can distinguish you from random passers-by.\n
