Many-body theory of excitation dynamics in an ultracold Rydberg gas
Cenap Ates, Thomas Pohl, Thomas Pattard +1
We develop a theoretical approach for the dynamics of Rydberg excitations in ultracold gases, with a realistically large number of atoms. We rely on the reduction of the single-ato…
Antiblockade in Rydberg excitation of an ultracold lattice gas
Cenap Ates, Thomas Pohl, Thomas Pattard +1
It is shown that the two-step excitation scheme typically used to create an ultracold Rydberg gas can be described with an effective two-level rate equation, greatly reducing the c…
Kinetic modelling and molecular dynamics simulation of ultracold neutral plasmas including ionic correlations
T. Pohl, T. Pattard, J. M. Rost
A kinetic approach for the evolution of ultracold neutral plasmas including interionic correlations and the treatment of ionization/excitation and recombination/deexcitation by rat…
On the possibility of "correlation cooling" of ultracold neutral plasmas
T. Pohl, T. Pattard, J. M. Rost
Recent experiments with ultracold neutral plasmas show an intrinsic heating effect based on the development of spatial correlations. We investigate whether this effect can be rever…
On the role of shake-off in single-photon double ionization
T. Pattard, T. Schneider, J. M. Rost
The role of shake-off for double ionization of atoms by a single photon with finite energy has become the subject of debate. In this letter, we attempt to clarify the meaning of sh…
Plasma formation from ultracold Rydberg gases
T. Pohl, T. Pattard, J. M. Rost
Recent experiments have demonstrated the spontaneous evolution of a gas of ultracold Rydberg atoms into an expanding ultracold plasma, as well as the reverse process of plasma reco…
