Energetically-consistent collisional gyrokinetics
Authors: J. W. Burby, A. J. Brizard, and H. Qin
Abstract: We present a formulation of collisional
gyrokinetic theory with exact conservation laws for energy and
canonical toroidal momentum. Collisions are accounted for by a
nonlinear gyrokinetic Landau operator. Gyroaveraging and
linearization do not destroy the operator's conservation
properties. Just as in ordinary kinetic theory, the conservation
laws for collisional gyrokinetic theory are selected by the
limiting collisionless gyrokinetic theory.
