Consider a particle in an infinite square well, but instead of having the well from 0 to L as we have done in the past, it is now centered at 0 and the walls are at x = −L/2 and x = L/2.

(a) Draw the first four energy eigenstates of this well.

(b) Write the eigenfunctions for each of these eigenstates.

(c) What are the energy eigenvalues for this system?

(d) Can you find a general expression for the energy eigenstates for this well? (Hint: you should have a different form for even and odd solutions) (e) If instead, the well were from x = −L to x = L, how would these expressions change? Would the energy eigenvalues change? (And if so, how?)

Consider two non-interacting particles in an infinite square well. One is in a state ψm, the other in a state ψn with n≠m. Let’s assume that ψm and ψn are the ground state and 1st excited state respectively and that the two particles are identical fermions. The well is of width 1Å. What is the probability of finding a particle in the 1st excited state in a region of width 0.01Å? Does this change if the particles are distinguishable?
