摘要：
The effect of resonant coupling of electrons via LO phonons on multiphoton absorption spectra of free polarons is investigated by using the solution of the Schrödinger equation for the free polaron which is coupled to a circularly polarized electromagnetic wave in the dipole approximation, by utilizing the independent-particle approximation. Furthermore, it is pointed out that, in the dipole approximation, the same result can be obtained by the method consisting of a time-dependent unitary transformation to an accelerated frame of reference. © 1979 The American Physical Society.
