Abstract
Stochastic resonance is a phenomenon in which adding random noise to a system enhances the detection or transmission of a weak signal.It occurs when the noise interacts with the system's nonlinearity,thus improving signal-to-noise ratio and increasing sensitivity.Although parametric resonances in an atomic spinor Bose-Einstein condensate have been investigated,the question of whether one can observe stochastic resonance in such a system persists.In this study we propose a scheme for generating stochastic resonance in a cavity-spinor Bose-Einstein condensate coupling system.We demonstrate stochastic resonance through numerical calculations using the mean-field theory and truncated Wigner approximation methods.Furthermore,the characteris-tics of the system's response to noise and periodic signals are studied in detail.This study unravels a new scheme for observing stochastic resonance via linking atomic many-body physics with cavity quantum electrodynamics.
