On the Bound Optical Polaron
Sukla Mukhopadhyay, Tapas Mitra · Journal of the Physical Society of Japan · 1985
The optical polaron bound in a Coulomb potential is investigated using a simple canonical transformation. The freedom in the choice of the generator of the transformation in this method is utilised to calculate the ground state for different types of trial generators. The results for different ranges of the coupling constant α and the Coulomb impurity parameter β are critically examined and compared with the major available results due to others. In view of the overall good and selectively excellent results obtained and in view of its simplicity the method appears to be useful.
