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…
Towards Spacetime Entanglement Entropy for Interacting Theories
Yangang Chen, Lucas Hackl, Ravi Kunjwal +3
Entanglement entropy of quantum fields in gravitational settings is a topic of growing importance. This entropy of entanglement is conventionally computed relative to Cauchy hypers…
Evidences for interaction-induced Haldane fractional exclusion statistics in one and higher dimensions
Xibo Zhang, Yang-Yang Chen, Longxiang Liu +2
Haldane fractional exclusion statistics (FES) has a long history of intense studies, but its realization in physical systems is rare. Here we study repulsively interacting Bose gas…
Emergent ballistic transport of Bose-Fermi mixtures in one dimension
Sheng Wang, Xiangguo Yin, Yang-Yang Chen +2
The degenerate Bose-Fermi (BF) mixtures in one dimension present a novel realization of two decoupled Luttinger liquids with bosonic and fermionic degrees of freedom at low tempera…
An Interaction-Driven Many-Particle Quantum Heat Engine: Universal Behavior
Yang-Yang Chen, Gentaro Watanabe, Yi-Cong Yu +2
A quantum heat engine (QHE) based on the interaction driving of a many-particle working medium is introduced. The cycle alternates isochoric heating and cooling strokes with both i…
Observation of Quantum Criticality and Luttinger Liquid in One-dimensional Bose Gases
Bing Yang, Yang-Yang Chen, Yong-Guang Zheng +5
We experimentally investigate the quantum criticality and Tomonaga-Luttinger liquid (TLL) behavior within one-dimensional (1D) ultracold atomic gases. Based on the measured density…
Universal Properties of Fermi Gases in One-dimension
Wen-Bin He, Yang-Yang Chen, Shizhong Zhang +1
In this Rapid Communication, we investigate the universal properties of a spin-polarized two-component Fermi gas in one dimension (1D) using Bethe ansatz. We discuss the quantum ph…
Dimensionless ratios: characteristics of quantum liquids and their phase transitions
Yi-Cong Yu, Yang-Yang Chen, Hai-Qing Lin +2
Dimensionless ratios of physical properties can characterize low-temperature phases in a wide variety of materials. As such, the Wilson ratio (WR), the Kadowaki-Woods ratio and the…
