Rydberg-dressed magneto-optical trap.

Bounds, A.D. and Jackson, N.C. and Hanley, R.K. and Faoro, R. and Bridge, E.M. and Huillery, P. and Jones, M.P.A. (2018) 'Rydberg-dressed magneto-optical trap.', Physical review letters., 120 (18). p. 183401.


We propose and demonstrate the laser cooling and trapping of Rydberg-dressed Sr atoms. By offresonantly coupling the excited state of a narrow (7 kHz) cooling transition to a high-lying Rydberg state, we transfer Rydberg properties such as enhanced electric polarizability to a stable magneto-optical trap operating at < 1 μK. Simulations show that it is possible to reach a regime where the long-range interaction between Rydberg-dressed atoms becomes comparable to the kinetic energy, opening a route to combining laser cooling with tunable long-range interactions.
