基于自洽重整化自旋涨落模型，讨论了自旋涨落对强关联巡游费米子系统热性质的影响。在有限温度下，液态~ 3 He和重电子化合物的正相比热和磁化率可以用统一的SCR图像来描述，该图像包含了自旋涨落的模-模耦合，超出了无规相近似（RPA）.
The effect of spin fluctuations on the thermal properties of strongly correlated itinerant fermion systems is discussed based on the self-consistent renormalized (SCR) spin fluctuation model. Specific heat and magnetic susceptibility in the normal phase of liquid-3He and heavy electron compounds at finite temperatures are well described by the unified SCR picture including the mode-mode coupling of spin fluctuations beyond the random phase approximation (RPA).
