On Minimizing Phase Space Energies
Michael Updike, Nicholas Bohlsen, Hong Qin +1
A primary technical challenge for harnessing fusion energy is to control and extract energy from a non-thermal distribution of charged particles. The fact that phase space evolves…

An inclusive curvature-like framework for describing dissipation: metriplectic 4-bracket dynamics
Philip J. Morrison, Michael H. Updike
An inclusive framework for joined Hamiltonian and dissipative dynamical systems, which preserve energy and produce entropy, is given. The dissipative dynamics of the framework is b…
