Аннотация: A method of producing and confining ultracold electron-ion plasma with a strongly nonideal ion subsystem is considered. The method is based on the laser cooling of plasma ions by the radiation resonant with the ion quantum transition. A model is developed for the laser cooling of recombining plasma. Computer simulation based on this model showed that the ion nonideality parameter can be as large as similar to100. The data obtained demonstrate that the production of ultracold nonideal plasma is quite possible. (C) 2002 MAIK "Nauka / Interperiodica".

Resonant optical characteristics of an ultracold laser plasma

Аннотация: We report a computer simulation study of light absorption, scattering and emission at 397 nm in an ultracold calcium ion plasma under resonant excitation. The results point to spectral asymmetry of light scattering, nonlinear absorption, and emission in the plasma. An approach is proposed for ultracold plasma diagnostics using resonant optical characteristics.

Laser Cooling of an Expanding Ultracold Plasma

Аннотация: We analyze the resonance absorption spectrum of ions in an expanding ultracold spherical plasma. It is shown that the spectrum width is controlled by the highest expansion velocity at the sphere boundary. As the expansion velocity grows, the initial optical thickness of the medium decreases and the medium becomes transparent. We suggest a broadband laser radiation in the red absorption spectrum of ions be used to decelerate ions in an expanding plasma in order to achieve crystallization.

Absorption of laser radiation in ultracold plasma
[Text] / N. Y. Shaparev // Chin. Phys. B. - 2016. - Vol. 25, Is. 10. - Ст. 103203, DOI 10.1088/1674-1056/25/10/103203. - Cited References:12

Аннотация: In this paper, we analyze the spectral behavior (optical thickness, shape and linewidth) of laser radiation absorption under the correlation heating of ions in an ultracold plasma. The Voigt formula is used to find the absorption coefficient. The spectral line width is shown to grow with time while the optical thickness reduces. Our modeling results are in good agreement with the experimental findings reported in the literature.

Interaction of ultracold non-ideal ion-electron plasma with a uniform magnetic field

Аннотация: The method of molecular dynamics is used to study the behavior of an ultracold non-ideal ion-electron Be+ plasma in a uniform magnetic field. Our simulations yield an estimate for the rate of electron-ion collisions which is non-monotonically dependent on the magnetic field magnitude. Also they explicitly show that there are two types of diffusion: a classical one, corresponding to Brownian motion of particles, and Bohm diffusion when the trajectory of particles (guiding centers) includes substantial lengths of drift motion.
