Kinetic simulation of electron transport using electron magnethydrodynamic structures

Abstract

Recent researches show the possibility that dipolar vortex structures, which are moving solutions in electron magnetohydrodynamic model, are generated by laser plasma interaction and they are applicable to electron transport in high-density plasma. However, the consideration of immobile ion and zero temperature employed in the electron magnetohydrodynamic formalism is pretty restrictive. Therefore the kinetic effects due to finite electron temperature on propagation of electron magnetohydrodynamic dipolar structures have been firstly explored using two-dimensional Particle-In-Cell simulation. Results show that the dipolar structures propagate damping the magnetic fields and its lifetime becomes longer in the case of lower temperature.
