Non-trivial 2d space-times from matrices
Sumit R. Das
Solutions of matrix quantum mechanics have been shown to describe time dependent backgrounds in the holographically dual two dimensional closed string theory. We review some recent…

Bulk Couplings to Noncommutative Branes
Sumit R. Das
We propose a way to identify the gauge invariant operator in noncommutative gauge theory on a D-brane with nonzero B field which couples to a specific supergravity mode in the bulk…

The One Dimensional Matrix Model and String Theory
Sumit R. Das
We discuss the basic features of the double scaling limit of the one dimensional matrix model and its interpretation as a two dimensional string theory. Using the collective field…
