Competing Soft Modes and Tunable Multicriticality in a Generalized Two-Mode Quantum Rabi Model
Xiufeng Cao, Ofri Adiv, Neil G. R. Broderick
Multicritical phenomena play a central role in quantum many-body systems, yet their microscopic origin in light--matter platforms remains largely unexplored. Here we investigate a…
The transition from Quantum Zeno to anti-Zeno effects for a qubit in a cavity by modulating the cavity frequency
Xiufeng Cao, Qing Ai, C. P. Sun +1
We propose a strategy to demonstrate the transition from the quantum Zeno effect (QZE) to the anti-Zeno effect (AZE) by modulating the central frequency of the cavity mode. Our res…
A qubit strongly-coupled to a resonant cavity: asymmetry of the spontaneous emission spectrum beyond the rotating wave approximation
Xiufeng Cao, J. Q. You, Hang Zheng +1
We investigate the spontaneous emission spectrum of a qubit in a lossy resonant cavity. We use neither the rotating-wave approximation nor the Markov approximation. The qubit-cavit…
Dynamics and quantum Zeno effect for a qubit in either a low- or high-frequency bath: A non-markovian approach beyond the rotating-wave approximation
Xiufeng Cao, J. Q. You, H. Zheng +1
We use a non-Markovian approach to study the decoherence dynamics of a qubit in either a low- or high-frequency bath modeling the qubit environment. This approach is based on a uni…
Non-Markovian disentanglement dynamics of two-qubit system
Xiufeng Cao, Hang Zheng
We investigated the disentanglement dynamics of two-qubit system in Non-Markovian approach. We showed that only the couple strength with the environment near to or less than fine-s…
Non-Markovian coherence dynamics of driven spin boson model: damped quantum beat or large amplitude coherence oscillation
Xiufeng Cao, Hang Zheng
The dynamics of driven spin boson model is studied analytically by means of the perturbation approach based on a unitary transformation. We gave the analytical expression for the p…
