Description
We performed a theoretical study of the thermodynamic and magnetic properties of strongly correlated and hybridized electron systems. We used a modified version of the two-band Periodic Anderson Hamiltonian to model behavior of electrons in such systems. Using the improved truncation approximation for irreducible Green functions, we observed the appearance of four spectral density moments and four or five sub-bands in the non-magnetic density of states. Applying a magnetic field resulted in the density of states splitting into additional sub-bands. We also analyzed the influence of the spin-spin and electron hole excitations on the magnetic susceptibility, density of states, and specific heat in the intermediate valence and heavy-fermion regimes.
