- 中文摘要: In a recent study, we showed that the Grote-Hynes theory for the chemical reaction rate exhibits critical phenomena near a critical coupling strength and large solvent response times. Therefore it is possible to write the rate in a scaling form with a universal scaling function that depends only on the short-time behavior of the memory friction kernel. This study involved a friction kernel involving only one relaxation time. In this paper, we apply the same techniques to a crystal friction involving multiple timescales. We show that the rate shows critical behavior and obtain the universal scaling function. We find the asymptotic behavior of the rate in different regimes of interest. In this way, we uncover the rich mathematical structure of the reaction rate associated with the crystal friction with multiple timescales.
