STOCHASTIC RESONANCE WITHOUT SYMMETRY-BREAKING
No full textStochastic resonance in a bistable potential is characterized as a resonant synchronization effect of the random hopping mechanism. Most notably, synchronization may occur even in the absence of a coherent drive
DAMPING IN LOW-FREQUENCY MECHANICAL PENDULUMS
No full textA phenomenological equation of motion is proposed to account for two distinctive features of low-frequency inverted pendulums: frequency independent internal losses and instability at resonance frequencies below a critical threshold. The comparison with recent experimental data is discussed in detail. A new characterization of the background loss for a mass suspended as a pendulum by wires is also derived
