Résumé : The interplay between two instabilities respectively breaking space and time symmetries can give rise to spatially subharmonic oscillations generated by a self-induced parametric instability. In one-dimensional systems, the resulting dynamics consists in a pattern with two wave numbers oscillating with one frequency. Conditions are given for which this solution becomes phase unstable giving rise to spatiotemporal chaos.
