"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.
