玻色-爱因斯坦凝聚:什么,如何及以后

Bose-Einstein condensation: what, how and beyond

Vishwa Mittar

摘要:

在一个系统的最低能态中,在极低的温度下,非相互作用玻色子的宏观部分的堆积被称为玻色-爱因斯坦凝聚。在他们的理论预测之后,花了近70年的时间才观察到冷凝物。本文简要介绍了有关发展的历史、基本理论的要点、在碱原子气体中产生冷凝物的物理步骤和有关理论,以及近25年来所进行的研究工作的一些重要特点。已作出努力,提出材料的方式,它可以很容易地遵循本科生以及非专业人士,甚至可以用于课堂教学。

英文摘要:

The piling up of a macroscopic fraction of noninteracting bosons in the lowest energy state of a system at very low temperatures is known as Bose-Einstein condensation. It took nearly 70 years to observe the condensate after their theoretical prediction. A brief history of the relevant developments, essentials of the basic theory, physics of the steps involved in producing the condensate in a gas of alkali atoms together with the pertinent theory, and some important features of the research work carried out in the last about 25 years have been dealt with. An effort has been made to present the material in a manner that it can be easily followed by undergraduate students as well as non-specialists and may even be used for classroom teaching.
