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

TE Foster, H Fetsch, NJ Fisch - Journal of Plasma Physics, 2023 - cambridge.org
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 …
