Question asked by Filo student
For a particle in a box (length a, mass m), consider the addition of a perturbing potential: V(x) = 2x/a for x ∈ [0,a/2] and V(x) = A(1-x/a) for x ∈ [a/2,a].
- Evaluate the first-order correction to the unperturbed eigenvalues of the particle in a box due to this perturbing potential.
- Compare the behavior of the eigenstates with even quantum numbers against those with odd quantum numbers.
- Discuss whether or not you expect this perturbing potential to mix states with even and odd quantum numbers, explaining why.
- Evaluate the effect of the perturbation on the ground state wavefunction to first order by working out the coupling matrix elements.
