Replica symmetry breaking in 1D Rayleigh scattering system: theory and validations

Revealing the underlying patterns behind complex systems and predicting their behavior has become a focal point of current interdisciplinary research. In this study, researchers delved into the intrinsic mechanisms of complex systems behavior of photonic phase transitions in one-dimensional Rayleigh scattering systems by establishing a Rayleigh-scattering-phase-variation model with experimental realization. This work expands the current understanding of photonic phase transitions, which is an important reference value for the study of various complex systems. Furthermore, it advances the application of random fiber lasers in critical fields such as high-power laser devices.
