The Strongly Coupled Polaron on the Torus: Quantum Corrections to the Pekar Asymptotics

no code implementations • 29 Jan 2021 • Dario Feliciangeli, Robert Seiringer

We investigate the Fr\"ohlich polaron model on a three-dimensional torus, and give a proof of the second-order quantum corrections to its ground-state energy in the strong-coupling limit.

We consider the Fr\"ohlich Hamiltonian with large coupling constant $\alpha$.
