- To explore the unprecedented potential of matter-wave interferometry
- To look at (de)coherence in increasingly complex quantum systems.
BEC 1: We are constructing a coherently guided matter-wave interferometer. Our matter-waves will be made from Bose-Einstein Condensates (BEC). The interferometer will consist of a novel magnetic ring-shaped waveguide based on time-averaged adiabatic potentials (TAAP). A little ‘teaser’ movie of our TAAP can be seen here.
BEC 2: We have set up a second experiment, which will look at BEC at higher atom numbers. We recently demonstrated a novel atom laser, which has a record flux of 4 x 10^7 atom/s. We also made the coldest thermal source to date (200nK). We are now using our novel QUIC trap plus adiabatic potentials to look at phase properties of large elongated condensates.
Space Optics: We are developing a novel fibre distribution board for complex optical space missions like STE-QUEST.
In the future we plan to study the kinetics of the condensation process itself. We also plan to study the rise of coherence in phase-fluctuating condensates.
