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…
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…
Relativity and Diversity of Strong Coupling to Measured Subsystems
Renming Liu, Yi-Cong Yu, Xue-Hua Wang
The strong coupling between two subsystems consisting of quantum emitters and photonic modes, at which the level splitting of mixed quantum states occurs, has been a central subjec…
Ab-initio Mapping of Projected Local Density of States in Arbitrary Nanostructures: Application to Photonic Crystal Slabs and Cavities
Gengyan Chen, Yi-Cong Yu, Xiao-Lu Zhuo +5
Based upon projected local density of states (PLDOS) for photons, we develop a local coupling theory to simultaneously treat the weak and strong interaction between a quantum emitt…
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…
A unified approach to the thermodynamics and quantum scaling functions of one-dimensional strongly attractive Fermi Gases
Yi-Cong Yu, Xiwen Guan
In this letter we present a unified derivation of the pressure equation of states, thermodynamics and scaling functions for the one-dimensional (1D) strongly attractive Fermi gases…
