D-branes in Lorentzian AdS3
نویسنده
چکیده
We study the exact construction of D-branes in Lorentzian AdS3. We start by defining a family of conformal field theories that gives a natural Euclidean version of the SL(2,R) CFT and does not correspond to H3 , the analytic continuation of AdS3. We argue that one can recuperate the exact CFT results of Lorentzian AdS3, upon an analytic continuation in the moduli space of these conformal field theories. Then we construct exact boundary states for various symmetric and symmetry-breaking D-branes in AdS3.

Boundary States of D-branes in AdS3 Based on Discrete Series
We study D-branes in the Lorentzian AdS3 background from the viewpoint of boundary states, emphasizing the role of open-closed duality in string theory. Employing the world sheet with Lorentzian signature, we construct the Cardy states with the discrete series. We show that they are compatible with (1) unitarity and normalizability, and (2) the spectral flow symmetry, in the open string spectru...
متن کاملhep-th/0211288 AdS2 D-Branes in Lorentzian AdS3
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 ...
متن کاملIsometric Embeddings and Noncommutative Branes in Homogeneous Gravitational Waves
We characterize the worldvolume theories on symmetric D-branes in a six-dimensional Cahen-Wallach pp-wave supported by a constant Neveu-Schwarz three-form flux. We find a class of flat noncommutative euclidean D3-branes analogous to branes in a constant magnetic field, as well as curved noncommutative lorentzian D3-branes analogous to branes in an electric background. In the former case the non...
متن کاملAdS3 Branes and Boundary States
We examine D-branes on AdS3, and find a three-brane wrapping the entire AdS3, in addition to 1-branes and instantonic 2-branes previously discussed in the literature. The three-brane is found using a construction of Maldacena, Moore, and Seiberg. We show that all these branes satisfy Cardy’s condition and extract the open string spectrum on them.
متن کاملAnti-de Sitter D-branes in Curved Backgrounds
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 ...
