Abstract:
Using the diagram technique in the atomic representation in the generalized chaotic phase approximation, we solve the problem of calculating the dynamical magnetic susceptibility of the periodic Anderson model in the strong electron correlation regime. We express the dynamical magnetic susceptibility in terms of four Matsubara Green's functions describing partial contributions, which are calculated based on exact solutions of integral equations.
Keywords:
periodic Anderson model, generalized chaotic phase approximation, dynamical magnetic susceptibility.
