论文摘要
使用OnSager的变分原理，我们得出了具有奇数弹性的非平衡活动系统的动力学方程。消除与非平衡驱动力耦合的额外变量导致材料坐标的非偏置方程组。所获得的非偏置方程表现出与非平衡力和摩擦系数成正比的奇数弹性常数的物理来源。我们的方法提供了一种系统且一致的方法，用于推导非重点方程，以破坏时间反转对称性的活动物质。
Using Onsager's variational principle, we derive dynamical equations for a nonequilibrium active system with odd elasticity. The elimination of the extra variable that is coupled to the nonequilibrium driving force leads to the nonreciprocal set of equations for the material coordinates. The obtained nonreciprocal equations manifest the physical origin of the odd elastic constants that are proportional to the nonequilibrium force and the friction coefficients. Our approach offers a systematic and consistent way to derive nonreciprocal equations for active matter in which the time-reversal symmetry is broken.
