论文摘要
光学晶格和自旋轨道耦合是工程师分散的典型实验方法。我们揭示了通过光学晶格或旋转轨道耦合与工程性分散剂的非相互作用的玻色网凝结物中的自我裂化动力学。自我干扰是由工程分散体中正和负面效应质量机制的共同占领而产生的。自我干扰的物理起源是通过自我拦截波包的Wigner分布函数来解释的。我们表征了自我干扰模式的细节特征。
Optical lattice and spin-orbit coupling are typical experimental approaches to engineer dispersion. We reveal a self-interfering dynamics in a noninteracting Bose-Einstein condensate with the engineered dispersion by optical lattice or spin-orbit coupling. The self-interference results from the co-occupation of positive and negative effect mass regimes in the engineered dispersion. The physical origination of the self-interference is explained by the Wigner distribution function of the self-interfering wave-packet. We characterize detail features of the self-interference pattern.
