| 摘 要： | 通过计算非费米液体重费米子体系的ＴＲ唯象模型中的集体激发对比 热的贡献，发现集体激发对比热的贡献与温度的４／３次幂成正比．这说明不能从 集体激发对比热的贡献来解释在实验上观察到的电子比热系数为温度的对数函数的非费来液体行为．

| Abstract: | We have calculated the contribution to the specific heat due to the collective excitations in the TR phenomenological model for non-Fermi-liquid heavyfermion systems and found that the contribution to the specific heat is proportional to 4/ 3 power of temperature. This shows that the experimentally observed non-Fermi-liquid behavior, that the electronic specific heat coefficient is a logrithmic function of temperature,cannot be accounted for by the contribution to the specific heat due to the collective excitations. |
