自干扰波包
Self-interfering wavepackets
摘要：
研究了非相互作用极化激元波包的传播。我们展示了两个质量不同的概念，从奇特的极化激元色散产生的非相互作用的领域-很像自加速光束-形成的拉比耦合高斯初始状态的一种新型的粒子状物体。扩散质量的发散和符号的改变导致极化激元波包反弹的“质量墙”。与拉比动力学一起，这产生了超快子包的传播和时空晶体的有序化。
英文摘要：
We study the propagation of non-interacting polariton wavepackets. We show how two qualitatively different concepts of mass that arise from the peculiar polariton dispersion lead to a new type of particle-like object from non-interacting fields---much like self-accelerating beams---shaped by the Rabi coupling out of Gaussian initial states. A divergence and change of sign of the diffusive mass results in a "mass wall" on which polariton wavepackets bounce back. Together with the Rabi dynamics, this yield propagation of ultrafast subpackets and ordering of a spacetime crystal.
