From: Observation of replica symmetry breaking in disordered nonlinear wave propagation
Evidence of replica symmetry breaking. a Overlap distribution measured for moderate nonlinearity \(t \simeq 18\) s and b in the highly-nonlinear regime at \(t \simeq 40\) s (input power P = 0.2 mW, cut-off scale R = 100 μm). c Overlap q max, corresponding to the maximum in P \(\left( {\left| q \right|} \right)\), as a function of the interaction strength. d Same as in b for data sets collected using different powers of the input wave (P = 5 mW, P = 12 mW). e Glass transition in the correlation functions shown by g α (x) up to R = 100 μm for different replicas (color dots) at \(t \simeq 18\) s and f at \(t \simeq 40\) s. The two well-separated groups of states in f form the basis for replica symmetry breaking. The black solid line in e, f indicates the average correlation \(\bar g(x)\)
