We present an experimental study of quasiperiodic transitions between ahighly ordered square-lattice pattern and a disordered, defect-riddled state,in a circular Faraday system. We show that the transition is driven initiallyby a long-wave amplitude modulation instability, which excites the oscillatorytransition phase instability, leading to the formation of dislocations in theFaraday lattice. The appearance of dislocations damps amplitude modulations,which prevents further defects from being created and allows the system torelax back to its ordered state. The process then repeats itself in aquasiperiodic manner. Our experiments reveal a surprising coupling between twodistinct instabilities in the Faraday system, and suggest that such couplingmay provide a generic mechanism for quasiperiodicity in nonlinear drivendissipative systems.
