Since a free particle cannot be reflected, the solution is valid for any possible value of ,. 5B either positive or negative – but not both at . potential well is a cube with . The equation for the energy gives Use Excel to plot a bar graph of the energies of the 3D infinite potential well, were you can vary , , and . This will give you
wave motions. Although these latter two are not eigenfunctions of px but are eigenfunctions of p2 x, hence of the Hamiltonian?H. Particle in a Box. This is the simplest non-trivial application of the Schrodinger equation, but one which illustrates many of the fundamental concepts of quantum mechanics. For a particle moving in
Lecture 17 - Particle in a 3D box. What's Important: • particle in a box. • Fermi energy. Text: Gasiorowicz, Chap. 9. In this lecture, we address the situation in which localized interactions are unimportant, so that particle wavefunctions span an entire system, perhaps even as large as a star. We start by considering the motion of

Use mathematics of separation of variables. (does not always work, but it works here):. Assume we could write the solution as: ?(x,y,z) = X(x)Y(y)Z(z). Plug it in the Schrodinger eqn. and see what happens! "separated function". 3D example: “Particle in a rigid box" a b c ?(x,y,z) = X(x)Y(y)Z(z) Now, calculate the derivatives for

b2 ). The lowest energy state is nx = ny = 1. If a>b, the next lowest energy state is nx = 2,ny = 1. When a = b, we have a degeneracy Enx,ny = Eny,nx. We can extend this particle in a box problem to the following situations: 1. Particle in a 3D box - this has many more degeneracies. This is the classic way of studying density of
