  • Experiments with Bose-Einstein Condensates aboard the Space Station: Quantum control and quantum sensing in the Coldest Spot in Space
    CQT Colloquium
    Speaker: Nicholas P. Bigelow, The University of Rochester
    Abstract: I will describe the work of the Consortium for Ultracold Atoms over the past four years using NASA’s and the Jet Propulsion Lab’s Cold Atom Laboratory (CAL), a shared user facility for investigating quantum matter in microgravity. In the first phases of our work we developed shortcut to adiabaticity protocols for transporting a rubidium Bose-Einstein Condensate (BEC) with positioning accuracy of ~70 nm and release velocity at or below the 100µm/s level. Deep cooling was similarly achieved using delta-kick-cooling to kinetic temperatures at or below 50 pK, creating the coldest spot in Space. I will also describe our preliminary atom interferometry experiments using both Rb and K, and our demonstration of high-performance sensing of magnetic fields and field gradients as well as preliminary tests of the Einstein Equivalence Principle.

    I was looking for similar experiment. Bose Einstein condensate was created by lene vestergaurd hau. That will be more useful for me. Please make video regarding that. Also if possible mention the cost of experiment too. If feasible i want to create some experiments myself with Bose Einstein condensate. Need to confirm some thought experiment.
