教育

1977年文小刚自陕西省西安市第四十八中学考入中国科学技术大学物理系,通过1981年度中美物理联合考试(CUSPEA)赴美攻读博士学位,名列当年CUSPEA考试第一名。1987年获得普林斯顿大学物理博士学位。[26]

在普林斯顿大学,文小刚在理论物理学家爱德华·威滕指导下学习超弦理论。后来,他与理论物理学家约翰·施里弗弗朗克·韦尔切克徐一鴻加利福尼亞大學聖塔芭芭拉分校理论物理研究所(1987-1989年)合作,将他的研究领域转变为凝聚体物理学

工作

文小刚引入了拓扑序(1989年)[2][3][27]量子序(2002年)[14]的概念来描述一类新的物质状态。这为凝聚态物理学开辟了新的研究方向。 他发现,拓扑序的状态包含非平凡的边界激励,并为边界状态开发了手性Luttinger理论(1990年)[4][5]。 边界状态可以成为理想的导电通道,这可能导致拓扑相的器件应用。 他提出了最简单的拓扑序 - Z2拓扑序(1990年)[6],这被证明是Toric code的拓扑序。 他还提出了一类特殊的拓扑序:非阿贝尔量子霍尔状态[10][11]。它们包含具有非阿贝尔统计的出现粒子,其一般化了众所周知的波色和费米统计。非阿贝尔粒子可以允许我们执行容错量子计算。

他的系列工作开辟了拓扑物态(topological state)、对称保护物态(symmetry protected state)、长程量子纠缠(long range entanglement)等物理新领域。

他是一本高级量子多体理论着作的作者: Quantum Field Theory of Many-body Systems: From the Origin of Sound to an Origin of Light and Electrons (Oxford University Press, 2004). 量子信息与量子物质交叉的专著:Quantum Information Meets Quantum Matter.
