论文摘要
我们研究了通过对称性破解二聚体的多体结构在更高维空间中自发过滤布朗尼运动的出现。相互作用的二聚体形式结构最终限制了个体成分的自由度旋转程度，从而导致集体运输的自发出现。在这种现象中，相互作用和断裂的结构对称性在集体转运中从热波动中脱颖而出。作为一种普遍的现象，布朗波动的自发滤波可能在复杂分子的结构过渡中起重要作用，而在克莱默斯（Kramers） - 结果过程中已知。这也可能是缺少的链接，以完全了解生物 - 聚合物的折叠过渡（蛋白质折叠）的基础知识，其中结构可能在相空间中编码运动。
We investigate emergence of spontaneous filtering of Brownian motion in higher dimensional space by many--body structures of symmetry broken dimer. Interacting dimer form structures which eventually restrict rotational degrees of freedom of individual constituents resulting in spontaneous emergence of collective transport. In this phenomenon, interaction and broken structural symmetry play cooperatively in emergence of collective transport out of thermal fluctuations. As a general phenomenon, spontaneous filtering of Brownian fluctuation might play an important role in the structural transition of complex molecules on top of what is known in terms of Kramers--rate process. This could also be a missing link to completely understand basics of bio--polymers' folding transitions (protein folding) where structure might encode motion in phase space.
