非平衡耗散系统的拓扑局部化

Topological localization in out-of-equilibrium dissipative systems

Kinjal Dasbiswas, Kranthi K. Mandadapu, Suriyanarayanan Vaikuntanathan

摘要:

在本文中,我们报告的拓扑保护的概念可以应用到固定的配置,驱动远离平衡的积极,耗散过程。我们表明,这在物理上两个不同的情况下:随机网络微观单粒子动力学以及集合驱动,相互作用的粒子描述的粗粒度流体动力学理论。在这两种情况下,破坏时间反演对称性的环境耗散耦合的存在对于确保拓扑保护至关重要。这些例子证明了拓扑保护的概念,建立在电子和机械系统的背景下,确实一般地扩展到平衡之外的过程。这种拓扑鲁棒边界模式对生物和合成系统都有影响。

英文摘要:

In this paper we report that notions of topological protection can be applied to stationary configurations that are driven far from equilibrium by active, dissipative processes. We show this for physically two disparate cases : stochastic networks governed by microscopic single particle dynamics as well as collections of driven, interacting particles described by coarse-grained hydrodynamic theory. In both cases, the presence of dissipative couplings to the environment that break time reversal symmetry are crucial to ensuring topologically protection. These examples constitute proof of principle that notions of topological protection, established in the context of electronic and mechanical systems, do indeed extend generically to processes that operate out of equilibrium. Such topologically robust boundary modes have implications for both biological and synthetic systems.
