论文摘要

我们研究了时间和空间连续系统的随机自由度之间的非转向性相互作用引起的热力学特性。我们表明,在相当普遍的条件下,单独的非交流耦合意味着通过系统的稳定能量流动,即非平衡。预测自由度的非交流耦合程度会使非马克维亚人具有复杂的内存类型的单变量langevin描述,为此我们找到了涉及信息流的广义第二法律。我们证明,非转录线性相互作用可用于设计非单调存储器,这是典型的,例如,时间延迟的反馈控制,并自动伴随着通过系统的非零信息流。此外,已经是单个非经验耦合程度的自由度可以从单个热浴中提取能量(在等温条件下),因此可以将其视为最小版的延时,自主的“麦克斯韦恶魔”的最小版本。同时,非互联体系统具有活性物质的特征,例如在没有全局粒子传输的情况下,在脉冲轨迹水平上输入正能量。

We study the thermodynamic properties induced by non-reciprocal interactions between stochastic degrees of freedom in time- and space-continuous systems. We show that, under fairly general conditions, non-reciprocal coupling alone implies a steady energy flow through the system, i.e., non-equilibrium. Projecting out the non-reciprocally coupled degrees of freedom renders non-Markovian, one-variable Langevin descriptions with complex types of memory, for which we find a generalized second law involving information flow. We demonstrate that non-reciprocal linear interactions can be used to engineer non-monotonic memory, which is typical for, e.g., time-delayed feedback control, and is automatically accompanied with a nonzero information flow through the system. Furthermore, already a single non-reciprocally coupled degree of freedom can extract energy from a single heat bath (at isothermal conditions), and can thus be viewed as a minimal version of a time-continuous, autonomous "Maxwell demon". At the same time, the non-reciprocal system has characteristic features of active matter, such as a positive energy input on the level of the flucuating trajectories, without global particle transport.
