Taming vibrational resonance by transient high frequency

Abstract

We investigate the phenomenon of vibrational resonance (VR) in a model of two-fluid plasma driven by biharmonic forcing. We introduce a transient high-frequency (HF) signal by implementing the control parameter τ that clips the HF in rationale with the time period of the system. We found that one can efficiently tame the emergence and characteristics of VR with the introduction of τ. We study a coupled 1D lattice and a 2D array of the model to decipher the influence of τ on VR. We derive the analytical response curve of the uncoupled model at τ=1/2 and find good congruence with the numerical results. When τ>0 reduces the influence of the HF signal, we found that the diminution of τ curtails the occurrence of VR. The study finds potential applications in the fields of engineering, physics, and biology where resonance due to vibration has to be damped.
