Neutral collisions in affecting diffusion and collective oscillation of magnetized complex plasma

By comparing with the Bohm-like diffusion 1/B of magnetized complex plasma, it is found that the neutral collisions, i.e., collisions between neutral gas and charged dust particles, nonlinearly damp the motion of the system at a rate much slower than 1/ν, where B is the external magnetic field and ν is the neutral collision frequency. The effects of neutral collisions on longitudinal and transverse waves are discussed based on the current-current correlation function. The non-damping feature of strong neutral collisions to shorter-wavelength modes is observed. The phonon energy of the system tends to be distributed into a broader k–ω space in the strong damping regime.By comparing with the Bohm-like diffusion 1/B of magnetized complex plasma, it is found that the neutral collisions, i.e., collisions between neutral gas and charged dust particles, nonlinearly damp the motion of the system at a rate much slower than 1/ν, where B is the external magnetic field and ν is the neutral collision frequency.
