Next, fold the bottom portion of the square about two-thirds of the way up. 7 Barriers and Tunneling I think it is safe to say that no one understands quantum mechanics. an infinite square well), we find that the squared-momentum (i. Infinite square well expectation value? solving the uncertainty in momentum of an electron in infinite well? Any suggestions on this urn model problem?. We take the potential energy to be zero inside the well which extends from x=-a/2 to x=+a/2 and to be infinite outside this region. High school physics FAQ High school physics poses questions from the profound to the peculiar. 3 Degeneracy (not including spin) of the lowest 10 energy levels in a quantum well, a quantum wire with square cross-section and a quantum cube with infinite barriers.
