Hamiltonian formulation of the modified Hasegawa Mima equation
Cristel Chandre, Philip J. Morrison, Emanuele Tassi
We derive the Hamiltonian structure of the modified Hasegawa-Mima equation from the ion fluid equations applying Dirac's theory of constraints. We discuss the Casimirs obtained fro…
Energy stability analysis for a hybrid fluid-kinetic plasma model
Philip J. Morrison, Emanuele Tassi, Cesare Tronci
In plasma physics, a hybrid fluid-kinetic model is composed of a magnetohydrodynamics (MHD) part that describes a bulk fluid component and a Vlasov kinetic theory part that describ…
Stability of compressible reduced magnetohydrodynamic equilibria - analogy with magnetorotational instability
Philip J. Morrison, Emanuele Tassi, Natalia Tronko
Stability analyses for equilibria of the compressible reduced magnetohydrodynamics (CRMHD) model are carried out by means of the Energy-Casimir (EC) method. Stability results are c…
