"Gravity from Averaging CFTs"

Abstract:

I will explore the idea that certain theories of gravity in Anti-de 
Sitter space are dual to an average over an ensemble of quantum 
theories, rather than to a specific quantum theory. I will describe an 
average over Narain’s family of two-dimensional conformal field theories 
which describe free bosons on a torus, and compute the partition 
function using the Siegel-Weil formula. The result takes the form of a 
sum over geometries as one would expect in a theory of gravity. But the 
gravitational theory looks more like a Chern-Simons theory than like 
Einstein gravity.
