Brownian motion of grains and negative friction in dusty plasmas
Within the approximation of dominant charging collisions the explicit microscopic calculations of the Fokker-Planck kinetic coefficients for highlycharged grains moving in plasma are performed. It is shown that due to ion absorption by grain the friction coefficient can be negative and thus the...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Within the approximation of dominant charging collisions the explicit microscopic
calculations of the Fokker-Planck kinetic coefficients for highlycharged
grains moving in plasma are performed. It is shown that due to
ion absorption by grain the friction coefficient can be negative and thus the
appropriate threshold value of the grain charge is found. The stationary
solutions of the Fokker-Planck equation with the velocity dependent kinetic
coefficient are obtained and a considerable deviation of such solutions
from the Maxwellian distribution is established. |
