Hamiltonian formulation of the gyrokinetic Vlasov-Maxwell equations
J. W. Burby, A. J. Brizard, P. J. Morrison +1
The gyrokinetic Vlasov-Maxwell equations are cast as an infinite-dimensional Hamiltonian system. The gyrokinetic Poisson bracket is remarkably simple and similar to the Morrison-Ma…
Energy-Casimir stability of hybrid Vlasov-MHD models
Cesare Tronci, Emanuele Tassi, Philip J. Morrison
Different variants of hybrid kinetic-fluid models are considered for describing the interaction of a bulk fluid plasma obeying MHD and an energetic component obeying a kinetic theo…
Hierarchical structure of noncanonical Hamiltonian systems
Z. Yoshida, P. J. Morrison
Topological constraints play a key role in the self-organizing processes that create structures in macro systems. In fact, if all possible degrees of freedom are actualized on equa…
On energy conservation in extended magnetohydrodynamics
Keiji Kimura, P. J. Morrison
A systematic study of energy conservation for extended magnetohydrodynamic (MHD) models that include Hall terms and electron inertia is performed. It is observed that commonly used…
Higher order Hamiltonian fluid reduction of Vlasov equation
Maxime Perin, Cristel Chandre, Philip Morrison +1
From the Hamiltonian structure of the Vlasov equation, we build a Hamiltonian model for the first three moments of the Vlasov distribution function, namely, the density, the moment…
Hybrid Vlasov-MHD models: Hamiltonian vs. non-Hamiltonian
Cesare Tronci, Emanuele Tassi, Enrico Camporeale +1
This paper investigates hybrid kinetic-MHD models, where a hot plasma (governed by a kinetic theory) interacts with a fluid bulk (governed by MHD). Different nonlinear coupling sch…
A hierarchy of noncanonical Hamiltonian systems: circulation laws in an extended phase space
Z. Yoshida, P. J. Morrison
The dynamics of an ideal fluid or plasma is constrained by topological invariants such as the circulation of (canonical) momentum or, equivalently, the flux of the vorticity or mag…
Experimental determination of radiated internal wave power without pressure field data
Frank M. Lee, M. S. Paoletti, Harry L. Swinney +1
We present a method to determine, using only velocity field data, the time-averaged energy flux and total radiated power for two-dimensional inter…
