Query: L-H transition dynamics in fluid turbulence simulations with
  neoclassical force balance   Spontaneous transport barrier generation at the edge of a magnetically
confined plasma is investigated. To this end, a model of electrostatic
turbulence in three-dimensional geometry is extended to account for the impact
of friction between trapped and passing particles on the radial electric field.
Non-linear flux-driven simulations are carried out, and it is shown that
considering the radial and temporal variations of the neoclassical friction
coefficients allows for a transport barrier to be generated above a threshold
of the input power.
