Picturing a Bose-Einstein Condensate as Particles One intriguing aspect of a macroscopic boson aggregate is that it can be described using macroscopic terminology, which focuses on things like collective oscillations, surface modes, and vortices. At the same time, these intrinsically quantum mechanical systems are composed of particles, and can also be discussed from that point of view. That leads to a description that centers on concepts like single particle excitations, multiple excitations, and correlations. My talk will discuss this dichotomy, and consider some physical implications of the particle viewpoint. I will also discuss how physical condensate properties connect with the behavior of smaller clusters of rare gas atoms.
