基于Half不相容统计的一维开放系统的多体约束和非热行为

Many-body constraints and non-thermal behavior in 1D open systems with Haldane exclusion statistics

Bo Xiong, Fiona J. Burnell

摘要:

我们研究了在耦合到玻色子浴的1维系统中,由Halfton不相容统计所施加的能级间能量约束对弛豫过程的影响。通过制定相关的福克空间的第二量子化的描述,我们确定了这种弛豫动力学的某些普遍特征,并表明它是一般慢于无自旋费米子。我们的研究集中在Calogero-Sutherland模型,它实现了Halcadine排除统计在一维,但我们的研究结果适用于任何系统,具有相关的模式,在福克空间的层间占用的限制。

英文摘要:

We study the impact of the inter-level energy constraints imposed by Haldane Exclusion Statistics on relaxation processes in 1-dimensional systems coupled to a bosonic bath. By formulating a second-quantized description of the relevant Fock space, we identify certain universal features of this relaxation dynamics, and show that it is generically slower than that of spinless fermions. Our study focuses on the Calogero-Sutherland model, which realizes Haldane Exclusion statistics exactly in one dimension; however our results apply to any system that has the associated pattern of inter-level occupancy constraints in Fock space.
