Supernovae, entanglement and falling apples: experiments with Bose-Einstein condensates

Three experiments encompassing a variety of BEC physics: squeezing-enhanced interferometry, BEC gravimetry, collapsing of BECs with attractive interactions.

In the last decade and a half, experiments with Bose-Einstein condensates by groups the world over have explored new regimes in condensed matter and atomic physics, tested foundations of quantum mechanics and promised applications from precision metrology to quantum computing. In this talk, I will present three experiments encompassing a variety of BEC physics. I will describe our progress towards squeezing-enhanced interferometry beyond the classical limit, and present results from a BEC gravimeter using large-momentum-transfer beamsplitting. I will also discuss our recent work on the bosenova phenomenon: the collapse of Bose-Einstein condensates with attractive interactions.
