Chapter 8: Tunneling in Symmetric and Asymmetric Local Potentials and Tunneling in Nonlocal and Quasi-Solvable Barriers

In the preceding chapter we studied some solvable examples where the wave functions were found analytically. Now we want to study the energy splitting and the motion of a wave packet in a double-well confining potential, and in particular to see the difference between the tunneling in a symmetric and an asymmetric potential. The level splitting caused by tunneling is an important feature of these potentials and plays an essential role in a large number of problems of molecular physics and chemical physics [1]–[5]…
