旋转光子晶体中的科里奥利-塞曼效应
Coriolis-Zeeman effect in rotating photonic crystal
摘要：
对于由渐逝耦合微腔制成的二维光子晶体，预测了旋转诱导的简并光子带的分裂。这种破缺能裂类似于外磁场中原子能级或电子（空穴）磁矩子能级的塞曼分裂。与孤立微腔相比，光子在微腔周期光子晶格中的轨道运动显示出显著增强这种科里奥利-塞曼分裂[D.L. Boiko，Optics Express 2，397（1998）]。运动方程表明，非定常旋转诱导光子态之间的量子跃迁，而且，这种跃迁将作为非定常引力场的来源。
英文摘要：
Rotation-induced splitting of the otherwise degenerate photonic bands is predicted for a two-dimensional photonic crystal made of evanescently coupled microcavities. The symmetry-broken energy splitting is similar to the Zeeman splitting of atomic levels or electron's (hole's) magnetic moment sublevels in an external magnetic field. The orbital motion of photons in periodic photonic lattice of microcavities is shown to enhance significantly such Coriolis-Zeeman splitting as compared to a solitary microcavity [D.L. Boiko, Optics Express 2, 397 (1998)]. The equation of motion suggests that nonstationary rotation induces quantum transitions between photonic states and, furthermore, that such transitions will serve as a source of nonstationary gravitational field.
