A double charged layer consisting of two parallel and ideal
uniformly charged planes is given, as shown in the figure. Let the
charge density per unit of surface of each floor equal to
C/.
where the upper floor is positively charged and the lower one
negatively charged.

A solid cylindrical conducting shell of inner radius a = 4.9 cm
and outer radius b = 6 cm has its axis aligned with the z-axis as
shown. It carries a uniformly distributed current I2 =
5.8 A in the positive z-direction. An inifinte conducting wire is
located along the z-axis and carries a current I1 = 3.8
A in the negative z-direction.

If A(z) = n≥0
,
then an is the n-th coefficient of A(z), for
which we also write = []A(z).
Sometimes it is useful to consider
coefficients with negative index, with the understanding that
ak = 0 for k < 0. The coefficient a0 is called the constant
coefficient,
and we also write a0 = A(0). The set of all formal series
over
C shall be denoted by C[[z]]....

The behavior of a spin-
particle in a uniform magnetic field in the z-direction,
, with the Hamiltonian
You found that the expectation value of the spin vector
undergoes Larmor precession about the z axis. In this sense, we can
view it as an analogue to a rotating coin, choosing the
eigenstate with eigenvalue
to represent heads and the eigenstate with eigenvalue
to represent tails. Under time-evolution in the magnetic field,
these eigenstates will “rotate” between each other.
