Spatiotemporal complexity in Ginzburg Landau equations for anisotropic systems
Nematic electroconvection is a paradigm example of pattern formation in anisotropic extended systems, where spatiotemporal chaos can arise at the onset of electroconvection. This dissertation is devoted to characterize and identify the instability mechanism generating the spatiotemporal complexity in the numerical simulations of a system of Ginzburg Landau equations, used to study the weakly nonlinear stability of waves' amplitudes of nematic electroconvective patterns. In particular, the following results pertaining to spatiotemporal complexity are discussed. First, the simulated patterns are ...
