Isochronous bifurcations in a two-parameter twist map
Michele Mugnaine, Bruno B. Leal, Alfredo M. Ozorio de Almeida +2
Isochronous islands in phase space emerge in twist Hamiltonian systems as a response to multiple resonant perturbations. According to the Poincaré-Birkhoff theorem, the number of i…
A nontwist field line mapping in a tokamak with ergodic magnetic limiter
Michele Mugnaine, José D. Szezech, Ricardo L. Viana +1
For tokamaks with uniform magnetic shear, Martin and Taylor have proposed a symplectic map has been used to describe the magnetic field lines at the plasma edge perturbed by an erg…
Hamiltonian description for magnetic field lines: a tutorial
Ricardo L. Viana, Michele Mugnaine, Iberê L. Caldas
Under certain circumstances, the equations for the magnetic field lines can be recast in a canonical form, after defining a suitable field line Hamiltonian. This analogy is extreme…
