Analysis: An electron is confined to a one-dimensional space with infinite potential barriers at x = 0 and x = L and a constant potential energy between 0 and L. The electron is described by the wave function, wave function symbol=C(Lx-x2). Set up (do not evaluate) an expression that gives the energy of the system. Why is it possible to know the exact value of energy, but only the average position?

Consider a free electron gas model for a system of Nq fermions that are confined to move in two dimensions instead of three (for example, Nq non-interacting electrons that are confined to move on a surface). The dimensions of this system are lx by ly so that the particles move in the region 0 < x < lx, 0 < y < ly; the potential is zero inside that region and infinite outside. a) Find the Fermi energy for this...
