The formalism for energy changing rate of an accelerated atom coupled with electromagnetic vacuum fluctuations
Anwei Zhang
The structure of the rate of variation of the atomic energy for an arbitrary stationary motion of the atom in interaction with a quantum electromagnetic field is investigated. Our…
Protection of entanglement between two two-level atoms
Anwei Zhang
The dynamical evolution of entanglement between two polarizable two-level atoms in weak interaction with electromagnetic vacuum fluctuations is investigated. We find that, for init…
Complementarity via error-free measurement in a two-path interferometer
Yanjun Liu, Jing Lu, and Lan Zhou
We study both the wave-like behavior and particle-like behavior in a general Mach-Zehnder interferometer with its asymmetric beam splitter. A error-free measurement in the detector…
Detecting macroscopic quantum coherence with a cavity optomechanical system
Qiang Zheng, Jianwei Xu, Yao Yao +1
The rigorous resource framework of quantum coherence has been set up recently and excited a wide variety of interests. Here we show that a quantum cavity optomechanical system, as…
Entanglement dynamics for uniformly accelerated two-level atoms coupled with electromagnetic vacuum fluctuations
Yiquan Yang, Jiawei Hu, Hongwei Yu
We investigate the entanglement dynamics of two uniformly accelerated atoms with the same acceleration perpendicular to their separation. The two-atom system is treated as an open…
Inhibiting decoherence of two-level atom in thermal bath by presence of boundaries
Xiaobao Liu, Zehua Tian, Jieci Wang +1
We study, in the paradigm of open quantum systems, the dynamics of quantum coherence of a static polarizable two-level atom which is coupled with a thermal bath of fluctuating elec…
High-order exceptional points in optomechanics
H. Jing, Ş. K. Özdemir, H. Lü +1
We study mechanical cooling in systems of coupled passive (lossy) and active (with gain) optical resonators. We find that for a driving laser which is red-detuned with respect to t…
Partially dark optical molecule via phase control
Z. H. Wang, Y. Li
We study the tunable photonic distribution in an optical molecule consisting of two linearly coupled single-mode cavities. With the inter-cavity coupling and two driving fields, th…
Protecting and enhancing spin squeezing under decoherence using weak measurement
Xiang-Ping Liao, Man-Sheng Rong, Mao-Fa Fang
We propose an efficient method to protect spin squeezing under the action of amplitude-damping, depolarizing and phase-damping channels based on measurement reversal from weak meas…
Casimir switch: steering optical transparency with vacuum forces
X. -f. Liu, Yong Li, H. Jing
The Casimir force, originating from vacuum zero-point energy, is one of the most intriguing purely quantum effects. It has attracted renewed interests in current field of nanomecha…
An efficient cooling of the quantized vibration by a four-level configuration
Lei-Lei Yan, Jian-Qi Zhang, Shuo Zhang +1
Cooling vibrational degrees of freedom down to ground states is essential to observation of quantum properties of systems with mechanical vibration. We propose two cooling schemes…
Detecting the Curvature of de Sitter Universe with Two Entangled Atoms
Zehua Tian, Jieci Wang, Jiliang Jing +1
Casimir-Polder interaction arises from the vacuum fluctuations of quantum field that depend on spacetime curvature and thus is spacetime-dependent. Here we show how to use the reso…
Generalized Centripetal Force Law and Quantization of Motion Constrained on 2D Surfaces
Q. H. Liu
For a particle moves on a 2D surface f(x)=0 embedded in 3D Euclidean space, the geometric momentum and potential are simultaneously admissible within the Dirac canonical quantizati…

Xizhou Qin, Feng Mei, Yongguan Ke +2
Strongly interacting topological states in multi-particle quantum systems pose great challenges to both theory and experiment. Recently, bound states of elementary spin waves (magn…
Irreversible degradation of quantum coherence under relativistic motion
Jieci Wang, Zehua Tian, Jiliang Jing +1
We study the dynamics of quantum coherence under Unruh thermal noise and seek under which condition the coherence can be frozen in a relativistic setting. We find that the frozen c…
