A Simplified Wave Function for Dressed Atoms

    Graphical Abstract
    • Abstract
  • A wave function for laser dressed atom is derived as a perturbative solution of the timedependent Schrdinger equation in the velocity gauge. With the use of the average excitation energy approximation and the closure approximation, the solution is reduced to a timedependent operator acting on the "bare" atomic state. In softphoton approximation, the average excitation energy only appears in the first and second order terms of field frequency. Such a simplified dressed wave function is useful in...
