论文摘要
我们介绍并研究了一类新型的传感器,其灵敏度随着设备的尺寸而呈指数增长。值得注意的是,这种剧烈的增强不依赖任何微调,而是被认为是对局部扰动的一种稳定现象。具体而言,这种引人注目的现象背后的物理机制与在非富裕拓扑系统中观察到的边界条件的异常敏感性密切相关。我们概述了混凝土平台,用于实际实施这些非炎性拓扑传感器(NTOS),从经典的元材料到合成量子材料。
We introduce and study a novel class of sensors whose sensitivity grows exponentially with the size of the device. Remarkably, this drastic enhancement does not rely on any fine-tuning, but is found to be a stable phenomenon immune to local perturbations. Specifically, the physical mechanism behind this striking phenomenon is intimately connected to the anomalous sensitivity to boundary conditions observed in non-Hermitian topological systems. We outline concrete platforms for the practical implementation of these non-Hermitian topological sensors (NTOS) ranging from classical meta-materials to synthetic quantum-materials.
