AI中文摘要：
输运可观测量的精度可通过熵产生和输运过程的活性，借助动力学和热动力学不确定关系得到约束。在线性玻色系统中，当用所关注测量接触的局域活性替代原活性时，这类不确定关系能给出紧约束，即便在强耦合区也成立。非线性（或相互作用）对这些局域约束的有效性和预测性有多大影响，以及该影响在多大程度上取决于活性的具体定义，是本文针对两个实验相关模型系统（谐振子网络和本质非线性的自旋-玻色模型）所研究的开放问题。研究给出了关于非线性如何影响甚至破坏局域动力学和热动力学精度约束的可实验验证预测。
英文摘要：
The precision of transport observables can be bounded by the entropy production and the activity of the transport process via kinetic and thermokinetic uncertainty relations. In linear bosonic systems, such uncertainty relations can provide tight bounds when the activity is replaced by a local activity of the measurement contact of interest---even in the strong-coupling regime. How much nonlinearities (or interactions) impact the validity and predictiveness of these local bounds and how much this impact depends on the concrete definition of activity are open questions that we address for two experimentally relevant model systems, a harmonic oscillator network and the intrinsically nonlinear spin-boson model. We thereby provide experimentally testable predictions on how nonlinearities impact or even break local kinetic and thermokinetic precision bounds.
