  particle drift
It is found that particle drift, or mass transport, is critically dependent on this mean current, and consequently on the value off/σ,f being the Coriolis parameter, and σ the angular frequency of the oscillation.
      
Several of the physics issues are discussed here, including single-particle drift surfaces and adiabaticity, central-cell resonant radial transport, magnetohydrodynamic stability analysis, and finite-beta equilibrium.
      
In a lightly ionized plasma, charged-particle drift due to collisions with neutral atoms occurs at different velocities:
      
The particle drift is conditioned by an auxiliary equation which is obtained through stochastic energy conservation; the logarithmic transform of this equation is the Schr?dinger equation.
      
Emphasis is given to the problems of determining the transport coefficient for diffusion in energy and position space and in assessing the importance of particle drift motion in three-dimensional modulation models.
