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.

自从贝肯斯坦和霍金的开创性论文发表以来，人们已经知道，量子黑洞应该由遵循热力学关系的混合状态来描述，类似于描述非引力系统的混合状态。提供一个一致的和完整的量子力学描述状态（称为微观状态），可以统计地解释上面提到的热力学定律，这仍然是一个挑战。该项目将从弦理论的角度关注这个问题，旨在更好地描述不同类型黑洞微观状态的一般特性。特别是，在弦理论中，黑洞被实现为许多基本成分的束缚态，例如微扰弦态和膜。不同的技术，从使用AdS/CFT对偶性到d膜存在下的弦振幅，将被用来获得有关微态性质的定量信息。
