1209.1939 (O. D. Skoromnik et al.)

Collapse-revival dynamics in strongly laser-driven electrons    [PDF]

O. D. Skoromnik, I. D. Feranchuk, C. H. Keitel
The relativistic quantum dynamics of an electron in an intense single-mode quantized electromagnetic field is investigated with special emphasis on the spin degree of freedom. In addition to fast spin oscillations at the laser frequency, a second time scale is identified due to the intensity dependent emissions and absorptions of field quanta. In analogy to the well-known phenomenon in atoms at moderate laser intensity, we put forward the conditions of collapses and revivals for the spin evolution in laser-driven electrons starting at feasible $10^{18}$ W/cm$^2$.
