老化玻璃中的棘轮效应
The Ratchet effect in an ageing glass
摘要：
本文研究了非对称入侵者在玻璃模型中的动力学行为。在平衡时，入侵者以平均零速度扩散。在模式耦合温度下突然淬灭到$T$之后，观察到在对数时间尺度上稳定的净平均漂移。这种现象在西奈模型的不对称版本中得到了很好的再现。入侵者的亚速度随着$T_{eff}/T$而增长，其中$T_{eff}$由响应相关比定义，对应于与两个热储层接触时热棘轮的一般行为。
英文摘要：
We study the dynamics of an asymmetric intruder in a glass-former model. At equilibrium, the intruder diffuses with average zero velocity. After an abrupt quench to $T$ deeply under the mode-coupling temperature, a net average drift is observed, steady on a logarithmic time-scale. The phenomenon is well reproduced in an asymmetric version of the Sinai model. The subvelocity of the intruder grows with $T_{eff}/T$, where $T_{eff}$ is defined by the response-correlation ratio, corresponding to a general behavior of thermal ratchets when in contact with two thermal reservoirs.
