A Gyrokinetic Study of Intermittency and Coherent Structures in Kinetic Alfv\'{e}nic Turbulence

Turbulence is a ubiquitous process in space and astrophysical plasmas that serves to mediate the transfer of large-scale motions to small scales at which the turbulence can be dissipated and the plasma heated. In situ solar wind observations and direct numerical simulations demonstrate that sub-proton scale turbulence is dominated by highly anisotropic and intermittent, low frequency, kinetic Alfv\'{e}nic fluctuations. Previous gyrokinetic studies of kinetic Alfv\'{e}n wave turbulence have focused on the energy transport and wave-like properties of the turbulence; however, a recent gyrokinetic simulation examined the non-local and non-self-similar nature of the energy cascade. We use the same simulation data to examine the intermittency and coherent structures that are responsible for the non-local energy cascade.
