    Quantum-classical correspondence of the Dirac equation with a scalar-like potential

    Quantum matrix elements of the coordinate, momentum and the velocity operator for a spin-1/2 particle moving in a scalar-like potential are calculated. In the large quantum number limit, these matrix elements ...

    Berry phases in the three-level atoms driven by quantized light fields

    A theoretical analysis of Berry’s phases is given for the three-level atoms interacting with external one-mode and two-mode quantized light fields. Three main results are obtained: (i) There is a Berry phase w...
