Black holes in String theory

自贝肯斯坦和霍金的开创性论文以来，人们知道量子力学黑洞应该用符合类似于描述非引力系统的热力学关系的混合态来描述。今天仍然是一个挑战，提供一个一致的和完整的量子力学描述的状态（称为微观态），可以解释统计热力学定律上述。该项目将从弦理论的角度关注这个问题，旨在更好地解释不同类型黑洞的微观状态的一般性质。特别是在弦理论中，黑洞被实现为许多基本成分的束缚态，如微扰弦态和膜。不同的技术，从使用的AdS/CFT对偶的弦振幅的D-膜的存在下，将被用来获得定量信息的性质相关的微观。

Since the seminal papers by Bekenstein and Hawking it is known that quantum mechanically black holes should be described by mixed states that obey thermodynamic relations analogous to those describing non-gravitational systems. It is still a challenge today to provide a consistent and complete quantum mechanical description of the states (called microstates) that can explain statistically the thermodynamic laws mentioned above. The project will focus on this problem from a string theory perspective and aims to better characterise the generic properties of the microstates for different types of black holes. In particular, in string theory, black holes are realised as bound states of many basic constituents, such as perturbative string states and branes. Different techniques, ranging from the use of the AdS/CFT duality to that of string amplitudes in presence of D-branes, will be employed to derive quantitative information on the nature of the relevant microstates.
