Download or read book Some Aspects of Polaron Theory written by Nikola? Nikolaevich Bogoli?ubov and published by World Scientific. This book was released on 1988 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is an amplification of a set of special lectures delivered by the authors in the Physics Department of Moscow State University. The linear polaron model is studied. It is shown that the system is soluble for arbitrary coupling interaction strength between the electron and lattice vibrations. Detailed calculational techniques for obtaining the correlation, spectral and Green functions are given. The thermodynamic properties of the system are studied within the framework of the functional method.
