In 2010 I started the first year of my PhD in the Atomic, Mesoscopic and Optical Physics group in the Cavendish Laboratory. My research will concentrate on studying novel aspects of Bose-Einstein Condensates (BECs) - dense atomic clouds at extremely cold temperatures unmatched anywhere in the universe. While creating BECs is a significant experimental challenge, they exhibit many properties found in other complex systems, e.g. superfluidity. Studying BECs ultimately leads to better understanding of superfluids, superconductors and collective phenomena in general.
