Control of absolute negative mobility via noise recycling procedure

摘要

Absolute negative mobility (ANM) is investigated in a spatially-periodic symmetric system under the influence of noise consisting of the superposition of a white Gaussian noise with the same noise delayed by time τ. The effects of the noise intensity σ, the time delay τ and feedback intensity ε in the noise recycling are discussed. It is found that the noise intensity σ and time delay τ can induce the phenomenon of ANM, while the feedback intensity ε can not induce it. This phenomenon of ANM can be tested in the setup consisting of a resistively and capacitively shunted Josephson junction device by using a vertical cavity surface emitting laser to generate the noise recycling procedure.
