论文摘要

我们对由催化化学反应驱动的模型微电学进行数值模拟。我们的模型包括结构变量与描述催化反应的非平衡变量之间的机械化学耦合。计算结构变量的时间相关函数,并根据奇数兰格文动力学进一步分析。我们获得有效的奇数弹性常数,该常数表现出催化微大麻的破裂时间反转对称性。在模拟中,我们分别估计称为非肾上腺素的数量,并表明其行为类似于奇数弹性的行为。

We perform numerical simulations of a model micromachine driven by catalytic chemical reactions. Our model includes a mechano-chemical coupling between the structural variables and the nonequilibrium variable describing the catalytic reactions. The time-correlation functions of the structural variables are calculated and further analyzed in terms of odd Langevin dynamics. We obtain the effective odd elastic constant that manifests the broken time-reversal symmetry of a catalytic micromachine. Within the simulation, we separately estimate the quantity called nonreciprocality and show that its behavior is similar to that of the odd elasticity.Our approach suggests a new method to extract the nonequilibrium properties of a micromachine only by measuring its structural dynamics.
