M-branes, Kerr/CFT correspondence, Horava gravity and noncommutative geometry

物理学中最有趣和最吸引人的问题之一是如何理解引力的量子理论。我的长期研究涉及加强和增加我们的粒子和引力物理学的知识，从粒子物理学，引力物理学和非对易几何的观点考虑与量子引力有关的具体问题。根据我们目前的知识，量子引力理论的最佳候选理论是超弦理论，它似乎表现出良好的微扰行为。在超弦理论中，自然界中所有的基本粒子和已知的力都是最基本的物体--一维弦--的不同状态的实现。然而，人们已经知道有五种不同的相容超弦理论。它们似乎只是以某种双重关系存在着

One of the most interesting and attractive problems in physics is that of understanding how to make sense of a quantum theory of gravity. My long-term research involves strengthening and increasing our knowledge of particle and gravitational physics by considering specific questions connected to quantum gravity from the viewpoints of particle physics, gravitational physics and noncommutative geometry. According to our present knowledge, the best candidate theory for a quantum theory of gravity is superstring theory, which seems to exhibit good perturbative behaviors. In superstring theory, all fundamental particles and known forces in nature are realizatiuons of different states of the most fundamental object; a one-dimensional string. However, it has been known for some time that there are five distinct consistent superstring theories. It seemed that they simply exist with some dual relations between them
