Interacting dynamic Wannier-Stark ladder driven by a periodic pulse train

Pulsars are unique astronomical objects in that their emission is in the form of a periodic pulse train. For most pulsars the pulse duty cycle is small, only a few per cent of the period. The shapes and intensities of individual pulses are in general quite variable. This is illustrated in Figure 1 which shows a series of individual pulses from PSR 1133 + 16. Despite this variation in shape of individual pulses, it is found that the mean or integrated pulse profile obtained by adding many pulses synchronously with the period is in most cases stable in shape.

Two novel circuit-independent RC nonautonomous chaotic oscillator structures are presented. Both structures rely on a periodic pulse-train as the driving force and on a comparator as the only source of nonlinearity.

We investigate bifurcations in responses of two Hodgkin–Huxley neurons coupled to each other and forced by a periodic pulse train, through the characteristics of synaptic transmissions with an α-function and a time delay. Based on a computational method we previously presented, we show a mechanism of transitions among various kinds of nonperiodic as well as harmonic and subharmonic frequency-locked oscillations. The bifurcation analysis clarifies dependence of sub- and supra-threshold dynamics on coupling and forcing effects.
