Heating of frozen Rydberg gases in a strong magnetic field

S. X. Hu

Molecular-dynamics simulations have been performed for frozen Rydberg gases in a strong magnetic field of B = 2.9 T, up to a microsecond time scale. We found that a small number of spontaneously ionized electrons may de-excite a large portion of Rydberg atoms, while the free electrons leave the frozen Rydberg gases along the B-field. Such de-excitations as well as Rydberg–Rydberg atom interactions can induce significant heating to strongly magnetized Rydberg gases. Kinetic energy increase by 2–3 orders of magnitude has been observed for the initially frozen (~0.2 mK) Rydberg gases.

Rydberg atom interactions from 300 K to 300 K

P. Pillet, Thomas F. Gallagher

Abstract Cold Rydberg atoms provide novel approaches to many-body problems and quantum simulation. To introduce the recent work presented in this special issue, we present here a quick history of a half-century research activity in the Rydberg-atom field, focusing our attention on the giant interactions between Rydberg atoms and other atoms. These interactions are the origin of many effects observed with Rydberg atoms: pressure shifts, dipole–dipole energy transfer, and avalanche-ionization. These effects have led to evidence of new bound chemical states, such as trilobites states, many-body effects in frozen Rydberg gases, and the spontaneous formation of ultra-cold plasmas. They open exciting new prospects at the intersection of atomic physics, condensed matter physics, and plasma physics.

Nonadiabatic Motional Effects and Dissipative Blockade for Rydberg Atoms Excited from Optical Lattices or Microtraps

Weibin Li, Cenap Ates, Igor Lesanovsky

The laser excitation of Rydberg atoms in ultracold gases is often described assuming that the atomic motion is frozen during the excitation time. We show that this frozen gas approximation can break down for atoms that are held in optical lattices or microtraps. In particular, we show that the excitation dynamics is in general strongly affected by mechanical forces among the Rydberg atoms as well as the spread of the atomic wave packet in the confining potential. This causes decoherence in the excitation dynamics-resulting in a dissipative blockade effect-that renders the Rydberg excitation inefficient even in the antiblockade regime. For a strongly off-resonant laser excitation-usually considered in the context of Rydberg dressing-these motional effects compromise the applicability of the Born-Oppenheimer approximation. In particular, our results indicate that they can also lead to decoherence in the dressing regime.
