双势阱玻色-爱因斯坦凝聚体中原子- laser外耦合的非马尔可夫动力学

Non-Markovian dynamics in atom-laser outcoupling from a double-well Bose-Einstein condensate

C. Lazarou, G. M. Nikolopoulos, P. Lambropoulos

摘要:

我们研究了基于独立形成的原子凝聚体合并的连续原子激光的动力学。在第一次尝试了解系统的动力学,我们考虑两个独立的细长的玻色-爱因斯坦凝聚体,相互接近,并专注于中间的陷阱间的距离,使一个双模模型是合理的。在平均场论的框架下,我们讨论了准稳态的陷阱布居以及耦合原子的能量分布。

英文摘要:

We investigate the dynamics of a continuous atom laser based on the merging of independently formed atomic condensates. In a first attempt to understand the dynamics of the system, we consider two independent elongated Bose-Einstein condensates which approach each other and focus on intermediate inter-trap distances so that a two-mode model is well justified. In the framework of a mean-field theory, we discuss the quasi steady-state population of the traps as well as the energy distribution of the outcoupled atoms.
