摘要
The periodic Anderson model for finite Coulomb repulsion U is studied using the equation of motion approach. The truncation approximation is employed to close the hierarchy of equations of motion for the connected Green's functions. The density-of-states is calculated self-consistently. The temperature and U dependence of the electronic specific heat, the linear specific heat coefficient are also discussed.
