A solution to a completely symmetric function and a completely antisymmetric function which also satisfy the Schrodinger equation with same energy and determine what happens to the completely antisymmetric function if ψ(r1,r2,r3,...rz) is symmetric in its first two arguments.

(b)

To determine

A point particle moves in space under the influence of a force derivablefrom a generalized potential of the formU(r, v) = V (r) + σ · L,where r is the radius vector from a fixed point, L is the angular momentumabout that point, and σ is the fixed vector in space. Find the components of the force on the particle in spherical polar  coordinates, on the basis of the equation for the components of the generalized force Qj: Qj = −∂U/∂qj + d/dt (∂U/∂q˙j)
In class, we developed the one-dimensional particle-in-a-box model and showed that the wavefunction Ψ(x) = Asin(kx), where k = nπ/l, where n is a positive integer and l is the length of the box: (a) by normalizing the wavefunction, determine the constant A; (b) by applying the Hamiltonian, determine the expression for energy as a function of n and l.
According to Ehrenfest's theorem, the time evolution of an expectation value <A>(t) follows the Ehrenfest equations of motion (d/dt)<A>(t) = (i/[hbar])<[H,A]>(t). For the harmonic oscillator, the Hamiltonian is given by H = p2/2m + m[omega]2x2/2. a) Determine the Ehrenfest equations of motion for <x> and <p>. b) Solve these equations for the initial conditions <x> = x0, <p> = p0, where x0 and p0 are real constants.
