| Abstract: | With the method of quantum field theory of solids the general forms of Hamiltonians including nonlin- ear interaction between electrons and phonons are obtained and the Hamiltonians for three kinds of polarons are deduced.It is shown that both longitudinal phonons and transverse phonons have effects to the quadratic electron-phonon interactions. |
