DOI: 10.1063/5.0287907
Abstract: The metriplectic formulation of collisional guiding-center Vlasov–Maxwell–Landau theory is presented. The guiding-center Landau collision operator, which describes collisions involving test-particle and field-particle guiding-center orbits, is represented in terms of a symmetric dissipative bracket involving functional… read more here.
