A nonperturbative theory of the electron propagator is developed and used to calculate the one-particle Green’s function and tunneling density of states in strongly correlated electron systems. The method, which is based on a Hubbard–Stratonovich decoupling of the electron–electron interaction combined with a cumulant expansion of the resulting… CONTINUE READING
