摘要:

本文研究了用任意子实现的Hanbury Brown和Twiss(HBT)干涉仪。这样的装置可以直接探测初始不相关粒子的纠缠和分数统计。我们计算了阿贝尔Laughlin任意子的HBT互相关。我们计算的相关性表现出类似于玻色子的部分聚束,这表明潜在的电子自由度发生了重大的统计变化。我们还发现了任意子信号和相应的玻色子或费米子信号之间的质的差异,表明任意子不能简单地被认为是玻色子和费米子之间的中间体。

英文摘要:

We present a study of an Hanbury Brown and Twiss (HBT) interferometer realized with anyons. Such a device can directly probe entanglement and fractional statistics of initially uncorrelated particles. We calculate HBT cross-correlations of Abelian Laughlin anyons. The correlations we calculate exhibit partial bunching similar to bosons, indicating a substantial statistical transmuta- tion from the underlying electronic degrees of freedom. We also find qualitative differences between the anyonic signal and the corresponding bosonic or fermionic signals, indicating that anyons cannot be simply thought as intermediate between bosons and fermions.
