Ultracold neutral plasmas
M Lyon, SL Rolston - Reports on Progress in Physics, 2016 - iopscience.iop.org
By photoionizing samples of laser-cooled atoms with laser light tuned just above the
ionization limit, plasmas can be created with electron and ion temperatures below 10 K …

Fast correlation heating in moderately coupled electron–ion plasmas
If the electrons in a plasma are suddenly heated, the resulting change in Debye shielding
causes the ion kinetic energy to quickly increase. For the first time, this correlation heating …

Rydberg-atom formation in strongly correlated ultracold plasmas
G Bannasch, T Pohl - Physical Review A—Atomic, Molecular, and Optical …, 2011 - APS
In plasmas at very low temperatures, the formation of neutral atoms is dominated by
collisional three-body recombination, owing to the strong∼ T− 9/2 scaling of the …

Dissociation and the development of spatial correlation in a molecular ultracold plasma
Penning ionization initiates the evolution of a dense molecular Rydberg gas to plasma. This
process selects for pairs of excited molecules separated by a distance of two Rydberg orbital …
