Özet

The effective mass of the Frohlich polaron is calculated with the two-mode squeezed states in the intermediate-coupling region and found to be in close agreement with the results of other models. Within the same approach, the induced charge density around an electron in polar solids is calculated. Our result for this charge density contains an additional term which shows a feature in the spatial dependence as a manifestation of the squeezing effect.
