Question
This problem illustrates the application of Linear Variational Theory. Consider a particle of mass
m in-a-box of length 1 but with a potential energy inside of the box which slopes upwards.
V(x) = b(x – ) if 0 < x < 1
V(x) = co
otherwise
b is a constant which we will take in units of the particle in a box energies:
11h?n?
b =
2m
We will use a set of two basis functions consisting of the n=1 and n=2 particle in a box
eigenfunctions.
a. Show that the elements of the Hamiltonian matrix H11 and H22 can be calculated from the
usual particle in a box energies.
