Abstract

In the present work, we numerically simulate the dynamics of porous charged microparticles localized in surface radio-frequency trap under atmospheric conditions, taking into account laser irradiation. The dynamic system transition from bistability to states characterized by either one or three stable equilibrium points is revealed. The number of stable equilibrium points and their spatial position appear to depend on the magnitude of the particle gravity and optical pressure. The phase portraits of the particle trajectories are calculated for the each dynamic system state. The obtained results are generalized and discussed from a practical point of view
