The |13>-|1> electric-dipole allowed transition and the |3>-|2> magnetic-dipole allowed transition of the system are excited simultaneously by the electric field and the magnetic field, respectively, of the weak probe light field.
E], of the probe electric field driving the electric-dipole allowed transition |3>-|1>, and the normalized frequency is [GAMMA] = [[gamma].
In the sections that follow, we shall consider the equation of motion of the density matrix elements of the atomic system interacting with both the applied light field and the incoherent pump field, analyze the behavior of the electric- and magnetic-dipole allowed transitions, and then present the solution to the equation of the density matrix of the present atomic system for obtaining the explicit expressions for the microscopic electric and magnetic polarizabilities of the atomic system.

The idea behind the simulations is to generate many possible scenarios by varying the allowed transitions within the allowed intervals and selecting the most suitable ones.
