暂缺《外势场中玻色:爱因斯坦凝聚体的动力学研究(英文版)》作者简介

内容简介

稀薄原子气体中玻色-爱因斯坦凝聚的实现为研究原子物质波的非线性动力学性质提供了可能性,一些在非线性光学中熟知的奇异现象不断在玻色-爱因斯坦凝聚中被观察到。在过去二十年间,操控原子间相互作用的技术引起了人们广泛的关注。例如,通过磁场或光场Feshbach共振技术,人们可以有效地调节原子间的相互作用从而达到操控该系统的目的,特别地,在共振磁场附近,系统会呈现出丰富的新奇量子物理性质。在平均场理论框架下,稀薄气体的玻色-爱因斯坦凝聚体的动力学可以由Gross-Pitaevskii(GP)方程来描述,该方程的非线性项系数可以通过磁场或光场Feshbach共振技术来调制。在《外势场中玻色-爱因斯坦凝聚体的动力学研究》中,作者基于平均场近似的GP方程来研究外势场中的具有各种原子相互作用的玻色-爱因斯坦凝聚体的新奇动力学。
