Asymmetric quantum steering harvested near a Lorentz-violating BTZ black hole
Si-Yu Liu, Xin-Ze Song, Xiang-Yue Yu +3
We investigate the harvesting of quantum steering and its directional asymmetry between two Unruh-DeWitt detectors in a Lorentz-violating BTZ black hole spacetime. Since the detect…

Unified signal response for stochastic resonance in bistable systems
Cong Liu, Xin-Ze Song, Zhi-Xi Wu +1
The phenomenon of stochastic resonance, wherein the stimulus-response of a system can be maximized by an intermediate level of noise, has been extensively investigated through line…

Optimizing and reducing stochastic resonance by noise color in globally coupled bistable systems
Cong Liu, Xin-Ze Song, Zhi-Xi Wu +1
We investigate the collective signal response of two typical nonlinear dynamical models, the mean-field coupled overdamped bistable oscillators and the underdamped Duffing oscillat…
