On the ground state energy of a polaron
✍ K.G. Chakraborty 📂 Article 📅 1974 🏛 Elsevier Science 🌐 English ⚖ 288 KB

A new decoupling approximation has been introduced in the Green's function equation-of-motion analysis of the large polaron. Considering those Feynman diagrams which correspond to the two-phonon Tamm-Dancoff approximations an expression for the polaron ground state energy has been derived. It is fou
