Abstract

Building a sensitive magnetic field sensor is non-trivial; building a more sensitive one by adding extra loss to the sensor is counterintuitive, but with innovative ideas from non-Hermitian physics like an exceptional point, a new magnetic field sensor first of its kind paves the way for broader applications of similar techniques.

一个“特殊”的磁传感器。

建立一个灵敏的磁场传感器是不平凡的；通过给传感器增加额外的损耗来制造一个更敏感的传感器是违反直觉的，但是从非厄米物理中获得的创新思想就像一个特殊的点，这种新型磁场传感器首次为类似技术的更广泛应用铺平了道路。
