摘要：
Due to the non-vanishing average photon population of the squeezed vacuum state, finite corrections to the scattering matrix are obtained. The lowest-order contribution to the electron mass shift for a one-mode squeezed vacuum state is given by deltam(Omega; s)/m = alpha(2/pi) (Omega/m)(2) sinh(2)(s), where Omega and s stand for the mode frequency and the squeeze parameter and a for the fine-structure constant, respectively.
