A fieldparticle correlation analysis of a perpendicular magnetized collisionless shock
Abstract
Using the fieldparticle correlation technique, we examine the particle energization in a threedimensional (one spatial dimension and two velocity dimensions; 1D2V) continuum VlasovMaxwell simulation of a perpendicular magnetized collisionless shock. The combination of the fieldparticle correlation technique with the highfidelity representation of the particle distribution function provided by a direct discretization of the Vlasov equation allows us to ascertain the details of the exchange of energy between the electromagnetic fields and the particles in phase space. We identify the velocityspace signatures of shockdrift acceleration of the ions and adiabatic heating of the electrons arising from the perpendicular collisionless shock by constructing a simplified model with the minimum ingredients necessary to produce the observed energization signatures in the selfconsistent VlasovMaxwell simulation. We are thus able to completely characterize the energy transfer in the perpendicular collisionless shock considered here and provide predictions for the application of the fieldparticle correlation technique to spacecraft measurements of collisionless shocks.
