For these graphs, they are wave functions of identical particles that are within an infinite square well and their width is a.
a.)What is the most probable value of the energy for each wave function and which state has the largest probable energy?
b.) Which of these states has the largest expectation value of the energy? (this part can be done without calculating the expectation value of the energy)

There is a 1-d infinite square well of width a, between x = 0 and a. We also know that V(x) = 0 for 0<x<a and +∞ elsewhere. Then we add a perturbation to it so that V(x) = ?_0 for 0 < x < a/2, and the same as before elsewhere. That is, a flat bump of width a/2 and height ?_0 in the left half of the well. Please answer following 3 questions. 1) Sketch the potential and...

A particle in the infinite square well has as its initial wave function an even mixture of the first two stationary states: psi(x, 0) = A[psi_1 (x) + psi_2(x)]. Normalize psi(x, 0) (that is, find A). Find psi (x) and |psi (x, )|^2. Express the latter as a sinusoidal function of time. To simplify the result, let omega = pi^2 h/2ma^2. Compute < x >? Compute < p >?
