摘要
本文运用线性响应理论推导共振价键(RVB)模型中 holon-spinon 散射和holon-phonon散射导致的正常态电阻率公式。计算结果表明:holon-spinon散射电阻率若用ρ-T~α公式拟合,α在1.4—1.5之间随温度变化;而声子散射电阻率在很大温度范围呈现线性温度行为。
In terms of the theory of linear response, we have studied the normal state resistivity due to holon-spinon scattering or holon-phonon scattering in a RVB system. The calculated results show that the resistivity due to holon-spinon scattering may be fitted by a formula ρ- Tα with α depending weakly on temperature and varying between 1.4 and 1.5, while the resistivity due to scattering by phonons exhabits linear temperature behavior in a wide temperature range.
