expression was asymptotically exact as α tends to infinity. Finally, Donsker and Varadhan, applying large deviation theory to Feynman`s path integral formulation for the self-energy, showed the large α exactitude of this Landau-Pekar formula. Later, Lieb and Thomas gave a shorter proof using more conventional methods, and with explicit bounds o....
