Exact mobility edges in Aubry-André-Harper models with relative phases
Xiaoming Cai, Yi-Cong Yu
Mobility edge (ME), a critical energy separating localized and extended states in spectrum, is a central concept in understanding the localization physics. However, there are few m…
Entanglement Entropy of Non-Hermitian Free Fermions
Yi-Bin Guo, Yi-Cong Yu, Rui-Zhen Huang +4
We study the entanglement properties of non-Hermitian free fermionic models with translation symmetry using the correlation matrix technique. Our results show that the entanglement…
Three-body bound states of two bosons and one impurity in one dimension
Yanxia Liu, Yi-Cong Yu, Shu Chen
We investigate one-dimensional three-body systems composed of two identical bosons and one imbalanced atom (impurity) with two-body and three-body zero-range interactions. For the…
Abnormal Critical Fluctuations Revealed by Magnetic Resonance in the Two-Dimensional Ferromagnetic Insulators
Zefang Li, Dong-Hong Xu, Xue Li +4
Phase transitions and critical phenomena, which are dominated by fluctuations and correlations, are one of the fields replete with physical paradigms and unexpected discoveries. Es…
Grüneisen parameters for Lieb-Liniger and Yang-Gaudin models
Li Peng, Yicong Yu, Xi-Wen Guan
Using the Bethe ansatz solution, we analytically study expansionary, magnetic and interacting Grüneisen parameters (GPs) for one-dimensional (1D) Lieb-Liniger and Yang-Gaudin model…
Grüneisen Parameters: origin, identity and quantum refrigeration
Yi-Cong Yu, Shizhong Zhang, Xi-Wen Guan
In solid state physics, the Grüneisen parameter (GP), originally introduced in the study of the effect of changing the volume of a crystal lattice on its vibrational frequency, has…
