Findings

Boundary states reproduce geometric brane configurations.

One-loop free energy matches open string calculations.

Supports the validity of boundary state construction in AdS_3.

Abstract

We construct boundary states for the AdS_2 D-branes in AdS_3. We show that, in the semi-classical limit, the boundary states correctly reproduce geometric configurations of these branes. We use the boundary states to compute the one loop free energy of open string stretched between the branes. The result agrees precisely with the open string computation in hep-th/0106129.
