abstract = {The dynamics of the Kelvin-Helmholtz instability are
investigated in the kinetic, high-frequency regime with a
novel, two-dimensional, mesh-free tree code. In contrast to
earlier studies which focused on specially prepared
equilibrium configurations in order to compare with fluid
theory, a more naturally occurring plasma-vacuum boundary
layer is considered here with relevance to both space plasma
and linear plasma devices. Quantitative comparisons of the
linear phase are made between the fluid and kinetic models.
After establishing the validity of this technique via
comparison to linear theory and conventional
particle-in-cell simulation for classical benchmark
problems, a quantitative analysis of the more complex
magnetized plasma-vacuum layer is presented and discussed.
It is found that in this scenario, the finite Larmor orbits
of the ions result in significant departures from the
effective shear velocity and width underlying the
instability growth, leading to generally slower development
and stronger nonlinear coupling between fast growing
short-wavelength modes and longer wavelengths.},
