摘要: The temperature dependence of the velocity sound is calculated for heavy fermions within a mean field approach. basic parameters periodic Anderson model, V and EO, are taken to be volume dependent. This leads chemical potential, mu , renormalized f level energy, epsilon /sup /f, number electrons, nf, hybridization V. These effects all included in calculation velocity.
