Titre |
Towards Microscopic Models of Big Bang Cosmology |
|
Résumé |
In this talk, we review an approach to describing cosmological
physics using ordinary AdS/CFT, where the cosmological physics is the
effective description of an end-of-the-world brane which cuts off the
second asymptotic region of a two-sided black hole. The worldvolume
geometry of the brane is an FRW big-bang/big-crunch spacetime. In
favorable circumstances, the brane acts as a Randall-Sundrum Planck
brane so that gravity localizes. We describe a microscopic construction
for such an end-of-the-world brane with localized gravity in AdS/CFT,
starting from N=4 SYM theory. We suggest specific microscopic states of
N=4 SYM theory that may encode the physics in a four-dimensional
cosmological spacetime. |
