Lead hopping, techniques

The summation over n is eliminated by the projection operator P and its complementary projection operator Q = I — P. The operator P projects to the IV-electron states with Nr electrons in the R-system. By acting on the states of eq. (1.227) it cuts off all the terms with electron distributions different from the required one. The general technique with the projection operator P in the previous section leads to the effective Hamiltonian with the intersubsystem electron hopping Wr projected out ... [Pg.81]
