Consider the excited state of a two-electron atom in which one of the electrons is in state u 1s* 0, rn 0, and the other electron in state n 2, 1 1, m 0. State the formal expression for the expectation value for the Coulomb energy between the two electrons in

How many permutations of a system of three fermions exist (including the identity operation)? How many of these permutations come with the eigenvalue —1?
In a system in which the Hamiltonian commutes with the time-reversal operator, can the wave function of an eigenstate to a non-degenerate eigenvalue be of the form /(z) Q(z) + ip(z), in which Q and y are linearly independent real and non-zero functions of z?

Consider a particle that moves in a double well potential, described by the Hamiltonian
+ vo,
a, b > o.
Show that >o is invariant imder the purity operation
Õ rim
well as under the time reversal operation ‘F.
We add a perturbation
to
Up, such that if – >o + *U. Here c > 0, and à is a small real and dimensionless parameter (note that the term òU renders the Hamiltonian Ú non-Hermitian, such that oomplex eigenvalues may occur). Determine whether if is invariant under the
Õ
and ‘ operations individually, as well as under the combined operation RÉ.
Suppose that {if, = 0, and that |Çy) is an eigenstate of žf with eigenvalue
E.
Show that, uiider these oonditions, also |Çp) is as eigenstate of if, and determine the corre- sponding eigenvalue Ê. How are
E
and Ê related in case that
|up) and |uy) describe the same quantum state?
|up) and |uy) are linearly independent, i.e. describe different quantum statee?
Suppose that the spectrum of the unperturbed Hamiltonian Up is non-degenerate and that the perturbation òÛ is turned on slowly by increasing z from zero, such that the eigenvalues E(à) are contínous functions of A. What follows for the spectrum, given that z remains small enough such that the eigenvalues E(A) remain non-degenerate?
Not
suppose that we enoounter complex eigenvalues E(A) for A > . What follows for the spectrum at A = ?
