Nonreciprocal Superradiant Phase Transitions and Multicriticality in a Cavity QED System
Gui-Lei Zhu, Chang-Sheng Hu, Hui Wang +3
We demonstrate the emergence of nonreciprocal superradiant phase transitions and novel multicriticality in a cavity quantum electrodynamics (QED) system, where a two-level atom int…
Quantum Magnetometer with Dual-Coupling Optomechanics
Gui-Lei Zhu, Jing Liu, Ying Wu +1
An experimentally feasible magnetometer based on a dual-coupling optomechanical system is proposed, where the radiation-pressure coupling transduces the magnetic signal to the opti…
Exceptional Point Generated Robust Asymmetric High-Order Harmonics
Gui-Lei Zhu, Amir Targholizadeh, Xin-You Lu +2
We propose a metallic-silicon system with a complex optical potential modulated along the length of the waveguide for a robust higher harmonic generation. For right moving fields w…
Interplay of quantum phase transition and flat band in hybrid lattices
Gui-Lei Zhu, Hamidreza Ramezani, Clive Emary +3
We investigate the interplay of superradiant phase transition (SPT) and energy band physics in an extended Dicke-Hubbard lattice whose unit cell consists of a Dicke model coupled t…
Single-photon-triggered quantum chaos
Gui-Lei Zhu, Xin-You Lü, Li-Li Zheng +3
We demonstrate how to manipulate quantum chaos with a single photon in a hybrid quantum device combining cavity QED and optomechanics. Specifically, we show that this system change…
Mass sensing by quantum criticality
Shang-Wu Bin, Xin-You Lü, Tai-Shuang Yin +3
Mass sensing connects the mass variation to a frequency shift of a mechanical oscillator, whose limitation is determined by its mechanical frequency resolution. Here we propose a m…
Entanglement and quantum superposition induced by a single photon
Xin-You Lü, Gui-Lei Zhu, Li-Li Zheng +1
We predict the occurrence of single-photon-induced entanglement and quantum superposition in a hybrid quantum model, introducing an optomechanical coupling into the Rabi model. Ori…
Controllable nonlinearity in a dual-coupling optomechanical system under a weak-coupling regime
Gui-Lei Zhu, Xin-You Lü, Liang-Liang Wan +3
Strong quantum nonlinearity gives rise to many interesting quantum effects and has wide applications in quantum physics. Herewe investigate the quantum nonlinear effect of an optom…
Single-Photon-Triggered Quantum Phase Transition
Xin-You Lü, Li-Li Zheng, Gui-Lei Zhu +1
We propose a hybrid quantum model combining cavity QED and optomechanics, which allows the occurrence of equilibrium superradiant quantum phase transition (QPT) triggered by a sing…
Single-photon-induced two qubits excitation without breaking parity symmetry
Qian Bin, Xin-You Lü, Shang-Wu Bin +2
We investigate theoretically the model of two \qubits" system (one qubit having an auxiliary level) interacting with a single-mode resonator in the ultrastrong coupling regime. We…
