Pattern formation and competition occur in a nonlinear extended medium if dissipation
allows for attracting sets, independently of initial and boundary conditions. This intrinsic …

A nonlinear system with delayed feedback, whenever the delay time is much longer than the
intrinsic correlation time, displays two widely separated time scales. In such a case, a two …

Homoclinic chaos is characterized by regular geometric orbits occurring at erratic times.
Phase synchronization at the average repetition frequency is achieved by a tiny periodic …

A single mode CW semiconductor laser with an optoelectronic feedback gives a modulated
output, with a sharp frequency peak depending on the feedback delay. A theoretical model …

We present an experimental and theoretical study of the dynamics of a CO 2 laser with
delayed feedback. Working with a delay time such that its product with the bandwidth of the …

The discrete distribution of homoclinic orbits has been investigated numerically and
experimentally in a CO 2 laser with feedback. The narrow chaotic ranges appear …

The nonlinear distributed optical system with rotation in 2-D feedback contour is considered.
A particular case of rotational multi-petal waves is described by bifurcational periodic …

Checks of homoclinic chaos made with nonlinear analysis techniques have been performed
on the signals coming from a CO_2 laser containing CH_3I as a saturable absorber. The …

We provide experimental evidence of the discrete character of homoclinic chaos in a laser
with feedback. We show that the narrow chaotic windows are distributed exponentially as a …

The functional dynamics exhibited by cell collectives are fascinating examples of robust,
synchronized, collective behavior in spatially extended biological systems. To investigate …
