Temporal evolution of (a) the electron and (b) the ion temperatures for the kinetic Alfvén turbulence simulation with ε_o = 0.50. The red lines are ﹩{T}_{\parallel {\rm{j}}}({\text{}}t)/{T}_{\parallel {\rm{j}}}(t=0)﹩, the green lines are ﹩{T}_{\perp {\rm{j}}}({\text{}}t)/{T}_{\perp {\rm{j}}}(t=0)﹩, the yellow lines are T_j(t)/T_j(t = 0), and the blue lines represent ﹩{T}_{\perp {\rm{j}}}/{T}_{\parallel {\rm{j}}}﹩. The dimensionless times are plotted here both as ω_pet and t/T_nl where the nonlinear time T_nlis defined as cited in, for example, Wu et al. (2013), Wan et al. (2015), Parashar et al. (2015a), and Matthaeus et al. (2016).
