Double-well potential: wavefunctions Following the prescription, usually assigned in folklore to E. M. Lifschitz – one of the authors of the famous Course on Theoretical Physics by L. D. Landau and E. M. Lifschitz – when a wavefunction for single well potential with minimum at u = 0 is known, Ψ(u), the wavefunction for double well potential with min- ima at u = 0, 1 can be written as Ψ(u) ± Ψ(u − 1). Double well potential: perturbation theory, tunneling, WKB (beyond instantons).	cache/ap-7671.pdf	txt/ap-7671.txt
