Abstract

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 a moderate laser intensity, we put forward the conditions of collapses and revivals for the spin evolution in laser-driven electrons starting at the feasible intensity of 10¹⁸ W/cm².
