Schep}, title = {Hamiltonian vortices and reconnection in a magnetized plasma}, abstract = {Hamiltonian vortices and reconnection in magnetized plasmas are investigated analytically and numerically using a two-fluid model. The equations are written in the Lagrangian form of three fields that are advected with different velocities. This system can be considered as a generalization and extension of the two-dimensional Euler equation for an ordinary fluid. It is pointed out that these equations allow solutions in. the form of singular current-vortex filaments, drift-Alfven vortices and magnetic islands, and admit collisionless magnetic reconnection where magnetic flux is converted into electron momentum and ion vorticity.}, year = {1998}, journal = {Journal of Plasma Physics}, volume = {59}, pages = {727-736}, month = {May-Jun}, isbn = {0022-3778}, doi = {10.1017/s0022377898006655}, language = {eng}, }
