【 摘 要 】

Dynamical properties of particles in the chain-like and layered structures are studied with the help of Langevin MD approach. We considered infinite, confined chain-like structures, and extended layered structures with vertical (chain-like) and hexagonal ordering of particles in adjacent layers over a wide range of parameters, corresponding to the experimental conditions in the laboratory dusty plasmas. The nonreciprocal anisotropic interparticle interaction leads to a growth of kinetic energy of stochastic motion of particles especially its vertical component. Efficacy of the heating depends on the thermal particle motion, the anisotropy of the considered interparticle interaction and with decreasing the friction coefficient.
