包含自聚焦Kerr介质的各向异性（二向色）光学腔显示出静态-伊辛和移动-布洛赫畴壁之间的分岔，即所谓的非平衡伊辛-布洛赫跃迁（NIB）。斑点墙可以表现出规律或不规则的时间行为，特别是破裂和尖峰。这些现象可以用由墙连接的扩展模式的时空动力学来解释，这些扩展模式也表现出复杂的动力学行为。域壁相互作用，包括束缚态的形成也被处理。
An anisotropic (dichroic) optical cavity containing a self-focusing Kerr medium is shown to display a bifurcation between static--Ising--and moving--Bloch--domain walls, the so-called nonequilibrium Ising-Bloch transition (NIB). Bloch walls can show regular or irregular temporal behavior, in particular, bursting and spiking. These phenomena are interpreted in terms of the spatiotemporal dynamics of the extended patterns connected by the wall, which display complex dynamical behavior as well. Domain wall interaction, including the formation of bound states is also addressed.
