Abstract:
Quantum signatures of a free electron in interaction with a continuous-wave radiation field are investigated by looking for negativities in the Wigner function of the system. The free-electron wave function in the radiation field is calculated fully analytically by solving the appropriate Schrödinger equation in the Krammers-Henneberger frame. It is found that pronounced quantum signatures show up already for a laser peak field of magnitude E0=1–2 a.u. and a frequency omega=1 a.u. However, the nonclassical behavior gets lost if the interaction with the radiation field is taken in the dipole approximation.
