Summary: | Spin glass theory, as a paradigm for describing disordered magnetic systems,
constitutes a prominent subject of study within statistical physics. Replica
symmetry breaking (RSB), as one of the pivotal concepts for the understanding
of spin glass theory, means that, under identical conditions disordered systems
can yield distinct states with nontrivial correlations. Random fiber laser
(RFL) based on Rayleigh scattering (RS) is a complex disordered system, owing
to the disorder and stochasticity of RS. In this work, for the first time, we
elaborate a precise theoretical model for studying the photonic phase
transition via the platform of RS-based RFL, in which we clearly reveal that,
apart from the pump power, the photon phase variation in RFL is also an analogy
to the temperature term in spin glass phase transition, leading to a novel
insight into the intrinsic mechanisms of photonic phase transition. In
addition, based on this model and real-time high-fidelity detection spectral
evolution, we theoretically predict and experimentally observe the
mode-asymmetric characteristics of photonic phase transition in RS-based RFL.
This finding contributes to a deeper understanding of the photonic RSB regime
and the dynamics of RS-based RFL. |
