Boundary States for AdS 2 Branes in AdS 3
نویسنده
چکیده
We construct boundary states for the AdS2 D-branes in AdS3. We show that, in the semiclassical 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.

AdS 2 D - Branes in Lorentzian AdS 3
The boundary states for AdS 2 D-branes in Lorentzian AdS 3 space-time are presented. AdS 2 D-branes are algebraically defined by twisted Dirichlet boundary conditions and are located on twisted conjugacy classes of SL(2,R). Using free field representation of symmetry currents in the SL(2,R) WZNW model, the twisted Dirichlet gluing conditions among currents are translated to matching conditions ...

In the light of the duality between physics in the bulk of anti-de Sitter space and a conformal field theory on the boundary, we review the M 2, D3 and M 5 branes and how their near-horizon geometry yields the compactification of D = 11 supergravity on S 7 , Type IIB supergravity on S 5 and D = 11 supergravity on S 4 , respectively. We discuss the " Membrane at the End of the Universe " idea an...

We investigate the properties of the AdS D1-branes which are the bound states of a curved D1-brane with n fundamental strings (F1) in the AdS3 spacetime, and the AdS D2-branes which are the axially symmetric bound states of a curved D2-brane with m D0-branes and n fundamental strings in the AdS3 × S spacetime. We see that, while the AdS D1-branes asymptotically approach to the event horizon of ...

Physical consistency of quantum fields in anti-de Sitter space time requires that the space must be compactified by the inclusion of a boundary where appropriate conditions are imposed. An interpretation for the presence of this boundary is found taking AdS as a limiting case of the space generated by a large number of coincident branes. The compactification of AdS leads to a discretization of ...
