Anomalous non-Hermitian skin effect: the topological inequivalence of skin modes versus point gap
Gang-Feng Guo, Xi-Xi Bao, Han-Jie Zhu +4
Non-Hermitian skin effect, the localization of an extensive number of eigenstates at the ends of the system, has greatly expanded the frontier of physical laws. It has long been be…
Emergent Quasiperiodicity from Polariton-phonon Hybrid Excitations in Waveguide Quantum Optomechanics
Han-Jie Zhu, Xiao-Ming Zhao, Jin-Kui Zhao +3
We investigate polariton-phonon hybrid excitations, which describe the collective excitations of emitter-photon polaritons and vibrational phonons, in a periodic array of vibrating…
Quantum speedup dynamics process in Schwarzschild space-time
Kai Xu, Han-Jie Zhu, Guo-Feng Zhang +2
Quantum speed limit time (QSLT) can be used to characterize the intrinsic minimal time interval for a quantum system evolving from an initial state to a target state. We investigat…
Finite-system Multicriticality at the Superradiant Quantum Phase Transition
Han-Jie Zhu, Kai Xu, Guo-Feng Zhang +1
We demonstrate the existence of finite-system multicriticality in a qubit-boson model where biased qubits collectively coupled to a single-mode bosonic field. The interplay between…
Universal Dissipationless Dynamics in Gaussian Continuous-variable Open Systems
Han-Jie Zhu, Guo-Feng Zhang, Lin Zhuang +1
We investigate the universal dissipationless dynamics of Gaussian continuous-variable systems in the presence of a band-gapped bosonic environment. Our results show that environmen…
The effects of different quantum feedback operator types on the parameter precision of detection efficiency in optimal quantum estimation
Shao-Qiang Ma, Han-Jie Zhu, Guofeng Zhang
The effects of different quantum feedback types on the estimation precision of the detection efficiency are studied. It is found that the precision can be more effective enhanced b…
Quantum Criticality in the Biased Dicke Model
Hanjie Zhu, Guofeng Zhang, Heng Fan
The biased Dicke model describes a system of biased two-level atoms coupled to a bosonic field, and is expected to produce new phenomena that are not present in the original Dicke…
Analytical Solution for the Anisotropic Rabi Model: Effects of Counter-Rotating Terms
Guofeng Zhang, Hanjie Zhu
The anisotropic Rabi model, which was proposed recently, differs from the original Rabi model: the rotating and counter-rotating terms are governed by two different coupling consta…
