One-loop corrections to the susceptibility and the specific heat in the periodic Coqblin-Schrieffer model

We investigate the periodic Coqblin-Schrieffer model in terms of the functional integral formalism, taking into account the one-loop corrections. We determine the order parameter corresponding to heavy fermion state for the symmetric case with isotropic hybridization, and calculate the thermodynamic quantities such as specific heat and susceptibility. We show how the one-loop corrections modify the thermodynamic quantities
