SUMMARY:Gravity from Averaging CFTs - Alexander Maloney (McGill)
DTSTART:20210429T120000Z
DTEND:20210429T130000Z
UID:TALK159076@talks.cam.ac.uk
CONTACT:Pietro Benetti Genolini
DESCRIPTION:I will explore the idea that certain theories of gravity in An
 ti-de\nSitter space are dual to an average over an ensemble of quantum\nth
 eories\, rather than to a specific quantum theory.  I will describe\nan av
 erage over Narain’s family of two-dimensional conformal field\ntheories 
 which describe free bosons on a torus\, and compute the\npartition functio
 n using the Siegel-Weil formula.  The result takes\nthe form of a sum over
  geometries as one would expect in a theory of\ngravity.  But the gravitat
 ional theory looks more like a Chern-Simons\ntheory than like Einstein gra
 vity.
