The modern world, with its computers, mobile phones, navigation systems, etc. functions on basis of quantum mechanics, as applied to solid state physics. Just as the dicovery of semiconductors ushered this new era half a century ago, new materials such as high temperature superconductors or carbon based nanotubes and graphene promise spectacular new technological developments. However, basic physical mechanisms operating in these materails and governing their conductive properties are at the moment rather poorly understood, and seem completely different from the known ones. My research hopes to contribute to the understanding of the physical problems posed by these new classes of materials. The goal is to, through discovery of new physical mechanisms, speed up the technological development, and at the same time use the new knowledge to understand some other relate fundamental problems in physics, such as some forms of the Bose - Einstein condensation, and the quark confinement.

现代世界的计算机、移动电话、导航系统等都是以量子力学为基础的，就像应用于固态物理一样。就像半个世纪前半导体的诞生开启了这个新时代一样，高温超导体、碳基纳米管和石墨烯等新材料有望实现壮观的新技术发展。然而，在这些材料中工作并控制其导电性能的基本物理机制目前还知之甚少，似乎与已知的完全不同。我的研究希望有助于理解这些新材料所带来的物理问题。其目的是通过发现新的物理机制，加快技术的发展，同时利用新的知识来理解物理学中其他一些相关的基本问题，如玻色-爱因斯坦凝聚的某些形式，以及夸克禁闭。
