研究领域

理论物理,量子多体理论

目前的科研兴趣

1个电子的物理可以通过薛定谔方程来解释。1026个电子就不是那么简单了,希尔伯特空间的维度指数增长。“量子多体理论”就是来对付这类问题的。通过几十年的努力,人们发现,在具有所谓“长程量子纠缠”的多体基态波函数里蕴藏着非常丰富的物理和数学结构,比如分数量子霍尔效应。即使在“短程量子纠缠”的多体基态波函数里,只要考虑全局对称性,我们也会得到非常丰富的相结构。 这些所谓“演生”(emergent)的现象是无法通过单体电子波函数来得到解释的。比如,分数量子霍尔态支持任意子的存在,一种既不是费米子也不是玻色子的粒子。这种粒子需要用Chern-Simons规范场论来描述。分数量子霍尔态的边界上(一个闭合环)有手征流,由共形场论(CFT)描述。

具体来讲,我目前感兴趣的课题有:
(i) (3+1)维及更高维的拓扑量子场论(TQFT)与n-扭结理论;
(ii) 拓扑量子物质态的分类与表征(含全局对称性);
(iii)非阿贝尔分数量子霍尔效应;拓扑序与张量范畴学
(iv)量子相变及其共形场论描述
(v)多体量子纠缠谱、纠缠熵
