Quantum tunneling with dissipative coupling
Pp. 109-126 (18)
This chapter is devoted to quantum tunneling, as a basic quantum process, essential for
important applications. Tunneling between two wells, of the double well potential of a one
particle system of interest, makes sense only when a second system, capable to distinguish
between the presence of the particle in a well, or in the other well, is present. The potential of
interaction between such two systems is called tunneling operator. We treat a few problems
of interest as tunneling in a quasi-continuum of states, the energy shift in a well by the
proximity of another well, dissipation effects, and tunneling spectrum.
