Trapping is an beneficial tool for investigations on and experiments with ions or microparticles. Optical resonance and fluorescence probing of isolated microparticles are essential to determine their spectroscopic fingerprints which gives information about their structural properties or internal degrees of freedom. On the other hand trapped ions are used for quantum computing or atomic clocks by manipulating their quantum states with systematic laser-light interaction. Ions can be trapped by optical cooling techniques such as Doppler cooling, while microparticles mainly lose their energy due to atmospheric friction. Although both processes are based on a different physical background, the dynamic of both can be described by an energy dissipation term proportional to the velocity of the particle. We have simulated the trapping process for a better understanding of the underlying dynamics and to test different trapping optimization approaches, for example exotic driving waveforms respectively for single particle trapping and two particles in a sympathetic cooling sheme.
