Physics & Astronomy Seminar: Blowing Bubbles....in Space!
Ryan Carollo, Postdoctoral Research Associate in the Physics & Astronomy Department at Bates College will speak. Bose-Einstein condensates (BECs) are a purely quantum-mechanical state of matter, where tens of thousands of atoms share the same wavefunction at extremely low temperatures (at the nanokelvin scale). These condensates can be used as sensitive probes or tests of delicate physics. There's only one problem - if they're held too weakly, they sag under gravity. NASA and JPL have solved this problem by installing a BEC machine (the Cold Atom Laboratory - CAL) on the International Space Station. We're using it to blow bubbles - fully-connected, quasi-2-dimensional shells of weakly-trapped condensate - and study them in a shape that can't be achieved on Earth.
