E4: The ring trap.

Following up on our previous work with a torroidal magnetic trap for ultracold atoms, E4 aims to fill a super-smooth microfabricated mm- to sub-mm scale torriodal magnetic trap with degenerate bosons and fermions (Lithium-6, Lithium-7, and Rubidium-87). With this setup, we will be able to explore interesting physics on mulitple fronts, including atom interferometry, vortices, and BECs in a non-trivial topology. By adding well-controlled potentials to our ring-trap, we may be able to see Josephson oscillations between different parts of the ring, in effect producing the atomic analog of a SQUID. Analogs to certain phenomena from accelerator physics may also be accessible.

More information about this project is coming soon.
