Hamiltonian derivation of the Charney-Hasegawa-Mima equation
Emanuele Tassi, Cristel Chandre, Philip J. Morrison
The Charney-Hasegawa-Mima equation is an infinite-dimensional Hamiltonian system with dynamics generated by a noncanonical Poisson bracket. Here a first principle Hamiltonian deriv…
Hamiltonian formulation and analysis of a collisionless fluid reconnection model
E. Tassi, P. J. Morrison, F. L. Waelbroeck +1
The Hamiltonian formulation of a plasma four-field fluid model that describes collisionless reconnection is presented. The formulation is noncanonical with a corresponding Lie-Pois…
On a new fixed point of the renormalization group operator for area-preserving maps
K. Fuchss, A. Wurm, P. J. Morrison
The breakup of the shearless invariant torus with winding number is studied numerically using Greene's residue criterion in the standard nontwist map. The residue be…
Meanders and Reconnection-Collision Sequences in the Standard Nontwist Map
A. Wurm, A. Apte, K. Fuchss +1
New global periodic orbit collision/separatrix reconnection scenarios in the standard nontwist map in different regions of parameter space are described in detail, including exact…
