Query: Generation of 'Super-Ponderomotive' Electrons due to a non-Wakefield
  interaction between a Laser Pulse and a Longitudinal Electric Field   It is shown that electrons with momenta exceeding the `free electron' limit
of $m_eca_0^2/2$ can be produced when a laser pulse and a longitudinal electric
field interact with an electron via a non-wakefield mechanism. The mechanism
consists of two stages: the reduction of the electron dephasing rate
$\gamma-p_x/m_ec$ by an accelerating region of electric field and electron
acceleration by the laser via the Lorentz force. This mechanism can, in
principle, produce electrons that have longtudinal momenta that is a
significant multiple of $m_eca_0^2/2$. 2D PIC simulations of a relatively
simple laser-plasma interaction indicate that the generation of
super-ponderomotive electrons is strongly affected by this `anti-dephasing'
mechanism.
