Exact results of dynamical structure factor of Lieb-Liniger model
Run-Tian Li, Song Cheng, Yang-Yang Chen +1
The dynamical structure factor (DSF) represents a measure of dynamical density-density correlations in a quantum many-body system. Due to the complexity of many-body correlations a…
One-body dynamical correlation function of Lieb-Liniger model at finite temperature
Song Cheng, Yang-Yang Chen, Xi-Wen Guan +2
The dynamical correlated properties of one-dimensional (1D) Bose gases provide profound understanding of novel physics emergent from collective excitations, for instance, the break…
Exact Spectral Function of One-Dimensional Bose Gases
Song Cheng, Yang-Yang Chen, Xi-Wen Guan +3
Exactly solved models provide rigorous understanding of many-body phenomena in strongly correlated systems. In this article, we report a breakthrough in uncovering universal many-b…
