摘要

广义Rosenfeld-Tarazona标度预测了简单液体的余热容对温度的幂律依赖性。两相模型将液体视为气固两类组分的叠加，其相对丰度由液体刚度参数量化。本文从液体刚度参数的标度不变性出发，证明了广义Rosenfeld-Tarazona标度在两相模型中自然出现。

Heat Capacity of Dense Liquids: A Link Between Two-Phase Model and Melting Temperature Scaling

Generalized Rosenfeld–Tarazona scaling predicts the power-law dependence of the excess heat capacity of simple liquids on temperature. The two-phase model treats a liquid as a superposition of gas- and solid-like components whose relative abundance is quantified by a liquid rigidity parameter. We demonstrate here that the generalized Rosenfeld–Tarazona scaling emerges naturally in the two-phase model from the scale invariance of the liquid rigidity parameter.
