The Eckhaus instability is a secondary instability of nonlinear spatiotemporal patterns in which high-wavenumber periodic solutions become unstable against long-wavelength perturbations. We show in this letter that this instability can take place in

Publikováno v: German French Russian Laser Symposium
German French Russian Laser Symposium, Apr 2018, Kazan, Russia

International audience; Delay dynamics are well known for their infinite dimensional phase space. An analogy with space-time dynamics was proposed 20 years ago from a theoretical perspective. In this talk, we will develop such an analogy from two par

Publikováno v: European Frequency and Time Forum
European Frequency and Time Forum, Apr 2018, Turin, Italy

International audience; We report Brillouin lasing in a monofluoride crystalline resonator for the very first time. While Raman scattering results from the interaction between a laser beam and an optical phonon providing a frequency shift in the THz

International Conference on Rebooting Computing, Nov 2017, Washington, United States

International audience; The prediction of complex signals is among the most important applications of random recurrent Neural Networks (rRNN). Yet, no theory which completely describes prediction in rRNNs exists. As such, these systems remain "black
