双阱晶格中超冷气体的非线性动力学
Nonlinear dynamics of ultracold gases in double-well lattices
摘要：
一个超冷气体被认为是，加载到一个晶格，其中每个网站是由一个双阱势。初始条件，加载后，对应于一个非平衡状态。系统的非线性动力学，从一个非平衡态，在本地场近似分析。考虑到衰减的重要性，所造成的粒子碰撞，强调。这种衰减的存在显著地影响系统动态。
英文摘要：
An ultracold gas is considered, loaded into a lattice, each site of which is formed by a double-well potential. Initial conditions, after the loading, correspond to a nonequilibrium state. The nonlinear dynamics of the system, starting with a nonequilibrium state, is analysed in the local-field approximation. The importance of taking into account attenuation, caused by particle collisions, is emphasized. The presence of this attenuation dramatically influences the system dynamics.
