  We present results from 2.5-dimensional Particle-in-Cell simulations of the
interaction of nonlinear Alfven waves with thin current sheets in relativistic
plasmas. We find that the Alfven waves cause the current sheet to bend and kink
and increase its dissipation. The electrons are eventually heated to form a
double Maxwellian, with the hotter Maxwellian caused by the current sheet
dissipation and cooler Maxwellian caused by the Alfven turbulence cascade.
These results may have important implications for the kinetic dissipation of
MHD turbulence in which both nonlinear Alfven waves and current sheets are
present, such as turbulence in accretion flows driven by the saturated
magnetorotational instability (MRI).
