Query: Electron dynamics in laser and quasi-static transverse electric and
  longitudinal magnetic fields   By deriving the 3/2 dimensional Hamiltonian equations for electrons in the
intense laser radiation and quasi-static transverse electric and longitudinal
magnetic fields, the electron heating mechanisms are examined both for low
harmonic resonance of electron frequency in the static fields with the laser
frequency and for high harmonic resonances where the overlapping of broadened
resonances causes the stochastic heating. For both cases, the maximum electron
kinetic energies, well beyond the ponderomotive scaling, depend only on a small
parameter combining the laser amplitude, electrostatic field strength and the
conserved dephasing rate.
