The net force acting on relativistic electrons caused by net inverse bremsstrahlung in a plasma wave

The net force acting on relativistic electrons in a laser-irradiated plasma is calculated by using both the pure classical electrodynamics and quantum mechanics. It is shown that the net force, averaged over the electron distribution, calculated by classical electrodynamics is zero, while that by quantum mechanics can exceed the oscillating Lorentz force of the laser wave when the electron energy is large and the momentum spread of the beam is properly controlled. We attribute it to the fact that inverse bremsstrahlung is not included in classical electrodynamics.
