Fluctuating periodic force

The electron distribution around an atom or molecule undergoes fluctuations in time. These fluctuations create instantaneous electric fields which are felt by other nearby atoms and molecules, which in turn adjust the spatial distribution of their own electrons. The net effect is that the fluctuations in electron … See more London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, fluctuating induced dipole bonds or loosely as van der Waals forces) are a type of See more The first explanation of the attraction between noble gas atoms was given by Fritz London in 1930.

Resonant behavior of a fractional oscillator with fluctuating mass

WebOct 3, 2012 · We examine the phenomenon of stochastic resonance of a fractional oscillator that has a random mass and is subject to an external periodic force. The colored fluctuations of the oscillator mass are modeled as a dichotomous noise. The viscoelastic type friction kernel with memory is assumed as a power law function in time.
