Multi-Parameter Multi-Critical Metrology of the Dicke Model
Luca Previdi, Yilun Xu, Qiongyi He +1
Critical quantum metrology exploits the hypersensitivity of quantum systems near phase transitions to achieve enhanced precision in parameter estimation. While single-parameter est…
Non-commutativity as a Universal Characterization for Enhanced Quantum Metrology
Ningxin Kong, Haojie Wang, Mingsheng Tian +4
A central challenge in quantum metrology is to effectively harness quantum resources to surpass classical precision bounds. Although recent studies suggest that the indefinite caus…
Boundary-induced Phases in the Dissipative Dicke Lattice Model
Peng-Fei Wei, Yilun Xu, Fengxiao Sun +3
The superradiant phase transition in the dissipative Dicke lattice model, driven by on-site collective atom-photon interactions and inter-site photon hopping, is a cornerstone of n…
Quantum phase transition in a quantum Rabi square with next-nearest-neighbor hopping
Yilun Xu, Feng-Xao Sun, Qiongyi He +2
We propose a quantum Rabi square model where both the nearest-neighbor and the next-nearest-neighbor photon hopping are allowed among four quantum Rabi systems located at the verti…
Phase transition and multistability in Dicke dimer
Yilun Xu, Feng-Xiao Sun, Wei Zhang +2
The exotic phase transitions and multistabilities in atom-cavity coupled systems have attracted tremendous interests recently. In this work, we investigate the effect of photon hop…
