Theoretical Physics

理论物理学的研究将涉及场论和超弦理论中的一系列基本问题。 场论，特别是杨-米尔斯规范理论，很好地描述了一般的强、弱和电磁力。 顶夸克物理学自两年前在费米实验室被发现以来一直非常重要。 我们使用量子色动力学中的重量化方法来详细研究与顶夸克物理相关的理论。 超引力是场论，它是超对称理论的低能极限，超弦理论已经成为统一引力与相对论和量子物理的唯一候选者。 研究将由非微扰和几何方面的超弦理论，对偶性在弦理论和自对偶杨米尔斯场理论，以及超引力和路径积分这些理论。

Research in theoretical physics will deal with a series of fundamental problems in field theory and superstring theory. Field theory, in particular Yang-Mills gauge theory, describes the strong, weak and electromagnetic forces in general very well. Top quark physics is very important since its discovery two years ago at Fermi Laboratory. We pursue in detail theories related to top quark physics using resummation methods in quantum chromodynamics. Supergravity is the field theory which is the low- energy limit of supersymmetry theory, and superstring theory has emerged as the unique candidate for uniting gravity with relativity and quantum physics. Studies will be made of nonperturbative and geometric aspects of superstring theory, duality in string theory and self-dual Yang-Mills field theories, as well as supergravity and path integrals for these theories.
