How Does a Bose-Einstein Condensate Develop Phase? The demonstration of Bose-Einstein Condensation in 1995 was a major milestone in physics. When atoms are extremely cold, their de Broglie wavelengths can overlap, forming a single macroscopic quantum fluid with well defined phase. Theorists have long pondered the origins of this phase. In this experimental program we aim to answer for the first time the intriguing question: "How does a BEC develop phase?". The answer will also be important fo ....How Does a Bose-Einstein Condensate Develop Phase? The demonstration of Bose-Einstein Condensation in 1995 was a major milestone in physics.

In this experimental program we aim to answer for the first time the intriguing question: "How does a BEC develop phase?". The answer will also be important for the recently developed atom laser - with potential applications as wide-reaching as the laser - where understanding the phase coherence is important for devices such as atom interferometers.Read moreRead less
Dynamic Correlations and Coherence Effects in Two-Electron Emission Processes. The electronic structure and properties of matter are determined by the correlated motion of electrons. Thus an understanding of this quantum mechanical many-body problem is central to our understanding of nature.

Such measurements also provide reference standards, with applications in many subfields (e.g. testing theories that indicate time dependence of the fundamental constants). Determination of the behaviour of simple molecules such as oxygen and nitrogen is important for understanding the complex processes that shape the atmosphere of the earth and other planets.
