耗散动力学经典场中夹杂物的拖曳力

Drag forces on inclusions in classical fields with dissipative dynamics

Vincent Demery, D. S. Dean

摘要:

我们研究了均匀运动的夹杂物上的拖曳力,这些夹杂物与通常用于研究软凝聚态系统的动力学自由场论线性相互作用。阻力被证明是非线性函数的夹杂物速度和强烈依赖于现场动力学。所获得的一般结果可以用来解释伊辛系统中的阻力,也预测存在的阻力蛋白质在膜由于耦合到膜的各种物理参数,如组成,相位和高度波动。

英文摘要:

We study the drag force on uniformly moving inclusions which interact linearly with dynamical free field theories commonly used to study soft condensed matter systems. Drag forces are shown to be nonlinear functions of the inclusion velocity and depend strongly on the field dynamics. The general results obtained can be used to explain drag forces in Ising systems and also predict the existence of drag forces on proteins in membranes due to couplings to various physical parameters of the membrane such as composition, phase and height fluctuations.
