We give an overview of UNP experiments with an emphasis on measurements of the time-evolving ion density and velocity distributions, the electron-ion thermalization rate, and plasma self-assembly—all just inside the strongly coupled plasma regime. We also present theoretical and computational models that were developed to understand a subset of HEDP experiments. However, because HEDP experiments display similar degrees of strong coupling, many aspects of these models can be vetted using precision studies of UNPs. This comparison is important because some statistical assumptions used for ideal plasmas are of questionable validity in the strongly coupled plasma regime. We summarize two theoretical approaches that extend kinetic theories into the strong-coupling regime and show good agreement for momentum transfer and self-diffusion. As capabilities improve, both computationally and experimentally, UNP measurements may help guide the ongoing development of HEDP-appropriate plasma models. Future opportunities in viscosity, energy relaxation, and magnetized plasmas are discussed.}, doiurl = {10.1063/1.5119144}, issn = {1070-664X, 1089-7674}, language = {en}, url = {https://pubs.aip.org/pop/article/26/10/100501/264042/ Exploring-the-crossover-between-high-energy}, } @article{killian_ultracold_2007, author = {Killian, Thomas C.}, journal = {Science}, month = may, number = {5825}, pages = {705--08}, title = {Ultracold {Neutral} {Plasmas}}, volume = {316}, year = {2007}, abstract = {Ultracold neutral plasmas occupy an exotic regime of plasma physics in which electrons form a swarming, neutralizing background for ions that sluggishly move in a correlated manner.

Describing plasmas theoretically is tricky when they are in the strongly coupled regime; reaching that regime in the laboratory would provide a valuable benchmark for theory. To that end, Langin et al. worked with a cold plasma created out of atoms of strontium that were ionized by laser light (see the Perspective by Bergeson). They used lasers to cool the ions down to about 50 millikelvin, reaching the desired strongly coupled regime. Science , this issue p. 61 ; see also p. 33 , Strontium ions in a neutral plasma created by photoionization were cooled to {\textasciitilde}50 mK, reaching the strongly coupled regime. , Laser cooling of a neutral plasma is a challenging task because of the high temperatures typically associated with the plasma state. By using an ultracold neutral plasma created by photoionization of an ultracold atomic gas, we avoid this obstacle and demonstrate laser cooling of ions in a neutral plasma. After 135 microseconds of cooling, we observed a reduction in ion temperature by up to a factor of four, with the temperature reaching as low as 50(4) millikelvin. This pushes laboratory studies of neutral plasmas deeper into the strongly coupled regime, beyond the limits of validity of current kinetic theories for calculating transport properties. The same optical forces also retard the plasma expansion, opening avenues for neutral-plasma confinement and manipulation.}, doiurl = {10.1126/science.aat3158}, issn = {0036-8075, 1095-9203}, language = {en}, url = {https://www.science.org/doi/10.1126/science.aat3158}, } @article{gorman_magnetic_2021, author = {Gorman, G. M. and Warrens, M. K. and Bradshaw, S. J. and Killian, T. C.}, journal = {Phys.
