Charged (nano)particles confined in electrodynamic traps can evolve into strongly correlated Coulomb systems, which are the subject of current investigation. Exciting physical phenomena associated to Coulomb systems have been reported such as autowave generation, phase transitions, system self-locking at the ends of the linear Paul trap, self-organization in layers, or pattern formation and scaling. The dynamics of ordered structures consisting of highly nonideal similarly charged nanoparticles, with coupling parameter of the order Γ = 10 8 is investigated. This approach enables us to study the interaction of nanoparticle structures in presence and in absence of the neutralizing plasma background, as well as to investigate various types of phenomena and physical forces these structures experience. Applications of electrodynamic levitation for mass spectrometry, including containment and study of single aerosols and nanoparticles are reviewed, with an emphasis on state of the art experiments and techniques, as well as future trends. Late experimental data suggest that inelastic scattering can be successfully applied to the detection of biological particles such as pollen, bacteria, aerosols, traces of explosives or synthetic polymers.

The results of calculations of the inner pressure and the energy of strongly coupled Coulomb systems in a Paul trap carried out by means of statistical theory of the liquid state are presented. Pair correlation functions of the Coulomb systems have been obtained. Full energy of the system, internal pressure, and the Coulomb coupling parameter Γ were calculated using the inter‐particle Coulomb potential. The considered system is highly non‐ideal with the coupling parameter of order Γ = 1010.

“…Linear electrodynamic quadrupole traps were used to create and study stable extended Coulomb structures containing thousands of charged dust particles . Studies have shown that linear traps are able to confine charged dust particles in air flows, and they can be used as selective filters for the purification of air from the dust particles . This paper is devoted to the investigation of the confining conditions of dielectric dust particles located on a dielectric surface under a linear electrodynamic trap and the possibility of cleaning dusty dielectric surfaces with the help of a linear electrodynamic trap.…”

This work is devoted to the experimental and numerical investigations of the possibility of cleaning dusty dielectric surfaces using an electrodynamic trap. We used a linear quadrupole Paul trap and polydisperse aluminium oxide particles in our experiments. Numerical simulations were performed using Brownian and molecular dynamic methods. The phenomenon of lifting and trapping of uncharged particles placed on the glass substrate located under the trap was experimentally observed. The parameters of the trap and charges of dust particles, which are necessary for drawing them from the substrate and confining in the trap, were also estimated using numerical simulations.
