Abstract

Systems with energy injection and dissipation self-organise by forming patterns of stripes, hexagons, squares, and superlattices at the onset of spatial instabilities. Increasing the disproportion between injection and dissipation of energy generates the emergence of disordered patterns with complex spatiotemporal behaviours. We investigate the turbulent dynamics of labyrinthine patterns far from the primary spatial instabilities in a liquid crystal light valve with optical feedback experiment. The structure functions associated with light intensity allow us to establish that the observed dynamical behaviours are also of intermittent nature.
