随机极限近似下受驱动自旋玻色子系统的量子随机共振
Quantum stochastic resonance in driven spin-boson system with stochastic limit approximation
摘要:
从物理角度简要回顾了自旋玻色子系统的随机极限近似,并在随机极限近似引入的量子白噪声的帮助下,观察到了受驱动自旋玻色子系统中的放大现象--随机共振现象。由于与环境的相互作用,系统的频率发生了变化-兰姆位移-在这些现象中起着重要的作用。
英文摘要:
After a brief review of stochastic limit approximation with spin-boson system from physical points of view, amplification phenomenon-stochastic resonance phenomenon-in driven spin-boson system is observed which is helped by the quantum white noise introduced through the stochastic limit approximation. The shift in frequency of the system due to the interaction with the environment-Lamb shift-has an important role in these phenomena.
