1. An electron in a finite well An electron is in a finite square well that is 20 eV deep and 0.25 nm wide. You may use all results from class/textbook without re-deriving therm A. (2 pts) By graphing both sides of the quantization condition like we did in class, determine how many bound energy eigenstates exist for this well. Don't forget that there are two quantization conditions, one for the even solutions, and one for the odd solutions! B....

2. Goal of this problem is to study how tunnelling in a two-well system emerges. In particular, we are interested in determining how the tunnelling rate T' of a particle with mass m scales as a function of the (effective) height Vo - E and width b of an energy barrier separating the two wells. The following graphics illustrates the set-up. Initially the particle may be trapped on the left side corresponding to the state |L〉, we are now interested...
