Entanglement of a Λ-type three-level atom with a single-mode field initially in the number state;

From Maxwell equations for free space and by converting the amplitudes in Fourier expansion of the vector potential into operators according to quantisation correspondence,this paper obtains Hamiltonian operator,which quantises the electromagnetic field,and introduces the number state representation for the field.
