1) where Hmj′ is the transition matrix element. For the one-dimensional case with a dependence on only the spatial variable x, the matrix element that connects the (initial) jth state with the (final) mth state via the perturbation hamiltonian H ′, is given by ′ H mj = ψ 0m H ′ ψ 0j = ∞ ∫ − ∞ ψ m ( x) 0* A( x) ψ 0j ( x) dx . e. H ′ = A(x) [ exp (iω0t) + exp (– iω0t) ], as expected for the excitation by a harmonic wave of a photon. 2) indicates that a necessary condition for recombination is spatial overlap between electron and hole wave functions.
