Microwave control of Rydberg atom interactions
Sevilay Sevinçli, Thomas Pohl
We investigate the interaction between Rydberg atoms, whose electronic states are dressed by multiple microwave fields. Numerical calculations are used for an exact description of…
Spin squeezing in a Rydberg lattice clock
L. I. R. Gil, R. Mukherjee, E. M. Bridge +2
Squeezed many-body states of atoms are a valuable resource for high precision frequency metrology and could tremendously boost the performance of atomic lattice clocks. Here, we th…
Strongly Coupled Plasmas via Rydberg-Blockade of Cold Atoms
G. Bannasch, T. C. Killian, T. Pohl
We propose and analyze a new scheme to produce ultracold neutral plasmas deep in the strongly coupled regime. The method exploits the interaction blockade between cold atoms excite…
Creating Non-Maxwellian Velocity Distributions in Ultracold Plasmas
J. Castro, G. Bannasch, P. McQuillen +2
We present techniques to perturb, measure and model the ion velocity distribution in an ultracold neutral plasma produced by photoionization of strontium atoms. By optical pumping…
Supersolid Vortex Crystals in Rydberg-dressed Bose-Einstein Condensates
N. Henkel, F. Cinti, P. Jain +2
We study rotating quasi-two-dimensional Bose-Einstein-condensates, in which atoms are dressed to a highly excited Rydberg state. This leads to weak effective interactions that indu…
Rydberg atom formation in strongly correlated ultracold plasmas
G. Bannasch, T. Pohl
In plasmas at very low temperatures formation of neutral atoms is dominated by collisional three-body recombination, owing to the strong ~ T^(-9/2) scaling of the corresponding rec…
