Collapse-revival dynamics in strongly laser-driven electrons — •Oleg Skoromnik1, Iliya Feranchuk2, and Christoph Keitel1 — 1Max Planck Institute for Nuclear Physics, Heidelberg, Germany — 2Belarusian State University, Minsk, Belarus
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 1018 W/cm2, arXiv:1209.1939.
