“…The first experiments with ultracold plasma [4][5][6] demonstrated an indication of the re-duction of recombination in such systems. Our theoretical works show the appearance of short and long-range order [7] and a large reduction of the recombination rate (a few orders of magnitude) in the ultra-cold mixture of Rydberg atoms and plasma in the presence of a strong magnetic field [8][9][10][11]. The ability to control the decay and crystallization processes in an ensemble of Rydberg atoms could find an application in quantum storage and quantum computers.…”

Our goal is the preparation and study of ultracold plasma and Rydberg matter. We assembled an experimental setup for laser cooling of lithium atoms in a magneto-optical trap (MOT). Trapping of 7 Li atoms in a MOT is demonstrated for a wide range of cooling laser detunings. The number density of 7 Li atoms at different ground-state sublevels is measured by using a probe tunable laser. The temperature of the trapped atoms is estimated. Obtained information is important for the preparation of ultra-cold plasma and highly-excited atoms.

“…At that time, calcu lations of the parameters of strongly nonideal plasma, in which the potential energy of charged particles is comparable to their kinetic energy, were not available. Our theoretical investigations based on numerical simulations using Monte Carlo and molecular dynam ics methods predicted the appearance of both short and long range order [8], as well as a significant (by several orders in magnitude) decrease in the recombination rate in the presence of a strong external magnetic field [9][10][11][12] for strongly interacting ultra cold Rydberg plasma. The study of these systems, as well as the ability to control the processes of their decay and crystallization, may provide a basis for the creation of quantum computers.…”

This study is aimed at obtaining high concentration of optically cooled lithium 7 atoms for pre paring strongly interacting ultracold plasma and Rydberg matter. A special setup has been constructed, in which two high power semiconductor lasers are used to cool lithium 7 atoms in a magneto optical trap. At an optimum detuning of the cooling laser frequency and a magnetic field gradient of 35 G/cm, the concentra tion of ultracold lithium 7 atoms reaches about 10 11 cm -3 . Additional independent information about the concentration and number of ultracold lithium 7 atoms on different sublevels of the ground state was obtained by using of an additional probing laser.
