弯曲时空中的半经典玻色D膜边界态

Semiclassical bosonic D-brane boundary states in curved spacetime

Ion V. Vancea

摘要:

本文给出了一种用微扰方法计算任意弯曲时空中玻色弦的半经典$D$膜边界态的简单方法,其中度规$g_{AB}$和常反对称Kalb-Ramond场$b_{AB}$构成严格处理的一般背景.作为一个重要的特例,证明了在一阶微扰理论下,当边界投影满足一定条件时,在$d$维{ \em AdS}时空中存在$D$ -膜相干态.

英文摘要:

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 $g_{AB}$ and the constant antisymmetric Kalb-Ramond field $b_{AB}$ 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 $D$-brane coherent states in the $d$-dimensional {\em AdS} spacetime if certain conditions are fulfilled by the boundary projectors.
