Journal of Physics A: Mathematical and General, 2000 Summary: The effect of a high-frequency force on the response of a bistable system to a low-frequency signal is considered for both the overdamped and weakly damped cases. It is shown that the response can be optimized by an appropriate choice of vibration amplitude.

Vibrational resonance in nonlinear vibration isolation systems [PDF]
Mechanics Research CommunicationsIn this study, we investigate vibrational resonance (VR) in a Duffing-type vibration isolation system using analytical and numerical approaches. Our results demonstrate that the response amplitude at low-frequency (LF) excitation can be enhanced by ...

Vibrational resonance in a Hodgkin-Huxley neuron
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015 In this paper, the effects of high-frequency driving on the weak signal detection capacity of Hodgkin-Huxley neuron are investigated. It is seen that the response of Hodgkin-Huxley neuron shows vibrational resonance with respect to the amplitude of high-frequency driving, and the best detection is obtained at an optimal amplitude of high-frequency ...

Internal vibrational resonance
Physics Letters ALanda and McClintock [J. Phys. A: Math. Gen. 33, L433 (2000)] discovered the vibrational resonance (VR), which is a resonant amplification in the system’s response to a slow periodic signal via a high-frequency harmonic drive. In this letter, we present another type of VR, called internal vibrational resonance (IVR), which is fundamentally different ...

Enhanced vibrational energy harvesting using non-linear stochastic resonance [PDF]
, 2008 Stochastic resonance has seen wide application in the physical sciences as a tool to understand weak signal amplification by noise. However, this apparently counter- intuitive phenomenon does not appear to have been exploited as a tool to enhance ...

Rotational–vibrational resonance states [PDF]
Physical Chemistry Chemical Physics, 2020 All molecular systems possess a significant number of rovibrational resonance states accessible via spectroscopic and scattering experiments, which can also be computed and rationalized by a variety of first-principles quantum-chemical techniques.

Ghost-vibrational resonance [PDF]
Communications in Nonlinear Science and Numerical Simulation, 2014 Ghost-stochastic resonance is a noise-induced resonance at a fundamental frequency missing in the input signal. We investigate the effect of a high-frequency, instead of a noise, in a single Duffing oscillator driven by a multi-frequency signal $F(t)= \sum^n_{i=1} f_i \cos(ω_i + Δω_0)t$, $ω_i=(k+i-1)ω_0$, where $k$ is an integer greater than or equal ...

Resonance Enhancement of Vibrational Polariton Chemistry Obtained from the Mixed Quantum-Classical Dynamics Simulations [PDF]
, 2023 We applied a variety of mixed quantum-classical (MQC) approaches to simulate the VSC-influenced reaction rate constant. All of these MQC simulations treat the key vibrational levels associated with the reaction coordinate in the quantum subsystem (as ...

Resonance Theory and Quantum Dynamics Simulations of Vibrational Polariton Chemistry [PDF]
, 2023 We present numerically exact quantum dynamics simulations using the hierarchical equation of motion (HEOM) approach to investigate the resonance enhancement of chemical reactions due to the vibrational strong coupling (VSC) in polariton chemistry.

Wobbling double sine-Gordon kinks
Journal of High Energy Physics, 2021 We study the collision of a kink and an antikink in the double sine-Gordon model with and without the excited vibrational mode. In the latter case, we find that there is a limited range of the parameters where the resonance windows exist, despite the ...
