Metrology with -symmetric cavities: Enhanced sensitivity near the -phase transition
Zhong-Peng Liu, Jing Zhang, Şahin Kaya Özdemir +7
We propose and analyze a new approach based on parity-time () symmetric microcavities with balanced gain and loss to enhance the performance of cavity-assisted metrol…
Noise suppression of on-chip mechanical resonators by chaotic coherent feedback
Nan Yang, Jing Zhang, Hui Wang +5
We propose a method to decouple the nanomechanical resonator in optomechanical systems from the environmental noise by introducing a chaotic coherent feedback loop. We find that th…
Feedback-induced nonlinearity and superconducting on-chip quantum optics
Zhong-Peng Liu, Hui Wang, Jing Zhang +3
Quantum coherent feedback has been proven to be an efficient way to tune the dynamics of quantum optical systems and, recently, those of solid-state quantum circuits. Here, inspire…
Suppressing nano-scale stick-slip motion by feedback
Jing Zhang, Re-Bing Wu, Lei Miao +4
When a micro cantilever with a nano-scale tip is manipulated on a substrate with atomic-scale roughness, the periodic lateral frictional force and stochastic fluctuations may induc…
Quantum Coherent Nonlinear Feedbacks with Applications to Quantum Optics on Chip
Jing Zhang, Re-Bing Wu, Yu-xi Liu +2
In the control of classical mechanical systems, the feedback has been successfully applied to the production of the desired nonlinear dynamics. However, how much this can be done i…
Transition from weak to strong measurements by nonlinear quantum feedback control
Jing Zhang, Yu-xi Liu, Re-Bing Wu +2
We find that feedback control may induce "pseudo" nonlinear dynamics in a damped harmonic oscillator, whose centroid trajectory in the phase space behaves like a classical nonlinea…
