we explore the dynamics of time-varying photonic media with an optical Kerr nonlinearity and an associated phase transition. The interplay between a periodically modulated permittivity and the nonlinearity induces a continuous transition of electromagnetic waves to a state with broken spatial and time translation symmetries. This transition gives rise to a lattice-like wave pattern, 在这项工作中,在许多方面类似于固体中的空间结晶,imToken钱包下载, in many ways similar to a spatial crystallization in solids. Symmetry breaking triggers the emergence of soft, 对称性破缺引发了软的、类似戈德斯通的模式的出现。
