两种体系中多重随机共振的噪声调控
Controlled Stochastic Multiresonance by Noise in Two Kinds Systems
【摘要】 通过计算机模拟 ,介绍一种新的方法来控制两种体系中的多重随机共振 ,被控参数选为噪声的脉冲间隔或噪声强度。对于对称的二能级的量子耗散体系 ,调节量子噪声则可以实现对量子多重随机共振的控制。另外还借用不同能级之间跃迁的观点来解释多重随机共振现象的形成机理。
【Abstract】 This paper introduces a new control scheme for controlling stochastic multiresonance (SMR) in two kinds of systems, through the variation of the noise pulse interval or intensity by computer simulation. Meanwhile, in quantum dissipative two-level system, quantum stochastic multiresonance can be realized by adjusting the quantum noise. In addition, this paper explained how the SMR forms in this kind of system by using the concept of hopping between different energy levels. The aspects of the SMR in this system are discussed.
