论文摘要
我们考虑弱相互作用的玻色气体的非平衡动力学紧密地局限于高度细长的双井潜力。我们将自洽的时间依赖性的hartree近似与整个三维理论的投影结合使用，以对几个耦合的一维通道进行投影。这使我们能够对最初局限于单个准单维电位的气体的时间依赖性分裂和相位刻度进行建模，并获得随之而来的抑制Josephson振荡的显微镜描述。
We consider the non-equilibrium dynamics of a weakly interacting Bose gas tightly confined to a highly elongated double well potential. We use a self-consistent time-dependent Hartree--Fock approximation in combination with a projection of the full three-dimensional theory to several coupled one-dimensional channels. This allows us to model the time-dependent splitting and phase imprinting of a gas initially confined to a single quasi one-dimensional potential well and obtain a microscopic description of the ensuing damped Josephson oscillations.
