Broadly speaking, my research deals with dilute atomic gases confined in space and cooled to extremely low temperatures. This combination of conditions results in remarkable physical properties that have captured the attention of physicists around the world. One example of this is the phenomenon of Bose-Einstein condensation (BEC) in which bosonic atoms condense into the lowest available quantum state, the condensate. In this novel state of matter, the atoms act coherently, and exhibit quantum behaviour on scales approaching macroscopic dimensions. One of the more dramatic consequences of BEC is superfluidity: the possibility of flow without resistance or dissipation.

广义地说，我的研究涉及被限制在太空中并被冷却到极低温度的稀释原子气体。这种条件的组合导致了引人注目的物理特性，引起了世界各地物理学家的注意。其中一个例子是玻色-爱因斯坦凝聚（BEC）现象，其中玻色子原子凝聚成最低的可用量子态，即凝聚态。在这种新的物质状态下，原子的行为是一致的，并在接近宏观尺度的尺度上表现出量子行为。BEC的一个更引人注目的结果是超流性：没有阻力或耗散的流动的可能性。
