Semiclassical bosonic D-brane boundary states in curved spacetime
نویسنده
چکیده
We give a simple method to calculate the semiclassical D-brane boundary states of the bosonic string propagating in an arbitrary curved spacetime in a perturbative approach in which the metric gAB and the constant antisymmetric Kalb-Ramond field bAB form the general background which is treated exactly. As an important particular case, it is shown that at the first order perturbation theory there are Dbrane coherent states in the d-dimensional AdS spacetime if certain conditions are fulfilled by the boundary projectors. ∗email:[email protected]

Conformally exact metric and dilaton in string theory on curved spacetime.
Using a Hamiltonian approach to gauged WZW models, we present a general method for computing the conformally exact metric and dilaton, to all orders in the 1/k expansion , for any bosonic, heterotic, or type-II superstring model based on a coset G/H. We prove the following relations: (i) For type-II superstrings the conformally exact metric and dilaton are identical to those of the non-supersym...
متن کاملMøller’s Energy-Momentum Complex for a Spacetime Geometry on a Noncommutative Curved D3-Brane
Møller’s energy-momentum complex is employed in order to determine the energy and momentum distributions for a spacetime described by a “generalized Schwarzschild” geometry in (3+1)-dimensions on a noncommutative curved D3brane in an effective, open bosonic string theory. The geometry considered is obtained by an effective theory of gravity coupled with a nonlinear electromagnetic field and dep...
متن کاملD-branes in the Light-cone Gauge and Broken Symmetries
Boundary states for D-branes are constructed using the light cone gauge. The D-brane breaks half the spacetime supersymmetry giving rise to fermionic zero modes living on the brane. The nonlinear realization of the broken supersymmetry on the open string degrees of freedom is analysed and the influence of boundary terms coming from closed string vertex operators is discussed. 1 Boundary states ...
متن کاملBosonic D-branes at finite temperature with an external field
Bosonic boundary states at finite temperature are constructed as solutions of boundary conditions at T 6= 0 for bosonic open strings with a constant gauge field Fab coupled to the boundary. The construction is done in the framework of the thermo field dynamics where a thermal Bogoliubov transformation maps states and operators to finite temperature. Boundary states are given in terms of states ...
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 ...
