Theoretical investigations of the properties of Rydberg matter, more precisely, a nonideal ultracold plasma, which is one of the forms of this matter, are reviewed. Monte Carlo and molecular dynamics studies indicate that structures with both short- and long-range orders can be formed and that the recombination coefficient in the case of strong nonideality, can be several orders of magnitude smaller than that under ideal conditions. These and other results obtained in the past several years are…

Kinetic processes in a nonideal Rydberg matter
A kinetic model is developed to describe ultracold nonideal Rydberg plasmas, which allows all stages of the generation and decay of such a plasma to be sequentially traced. The plasma kinetics is
Formation of Rydberg atoms in an expanding ultracold neutral plasma.
TLDR
This work studies the formation of Rydberg atoms in expanding plasmas at temperatures of 1-1000 K and densities from 10(5)-10(10) cm(-3), yet most of the results are inconsistent with this mechanism.
Rydberg atom formation in ultracold plasmas: small energy transfer with large consequences.
TLDR
Simulations of ultracold plasmas demonstrate that these corrections significantly impact the short-time dynamics of three-body Rydberg atom formation and improved rate coefficients yield quantitative agreement with recent ultrac old plasma experiments.
Relaxation to nonequilibrium in expanding ultracold neutral plasmas.
TLDR
It is shown that Gamma(i) calculated from the ionic temperature and density reflects the degree of order in the system if it is sufficiently close to a quasisteady state, and at later times, the expansion of the plasma cloud becomes faster than the relaxation of correlations, and the system does not reach thermodynamic equilibrium anymore.
Simulation of the expansion of an ultracold neutral plasma.
We report the results of simulations that explain many properties of ultracold neutral plasmas. We find that three-body recombination is important at very low temperatures since it is a heating
Electron–ion recombination in strongly coupled cold plasmas under nonequilibrium conditions
TLDR
The experimentally observed unexpectedly high recombination rate at long evolution times can be reproduced by a proper inclusion of these effects without the need to invoke alternative, previously suggested mechanisms, such as an 'adiabatic motional recombination' or the development of very strong electron correlations by collisional cooling.
Recombination properties of Rydberg nonequilibrium plasma created by dye laser
Ultracold Rydberg plasma formed by a dye laser has been studied theoretically. Recombination properties in the presence of three-body collisions in hydrogen-like plasma have been investigated. We
Kinetic modeling and molecular dynamics simulation of ultracold neutral plasmas including ionic correlations
TLDR
Comparison of the results reveals that the kinetic model describes the atomic and ionic observables of the ultracold plasma surprisingly well, confirming earlier findings concerning the role of ion-ion correlations.
