Abstract

Nitrogen vacancy (NV) centre quantum sensors provide unique opportunities in studying condensed matter systems, as they are quantitative, non-invasive, physically robust, offer nanoscale resolution and may be used across a wide range of temperatures. These properties have been exploited in recent years to obtain nanoscale resolution measurements of static magnetic fields arising from spin order and current flow in condensed matter systems. Compared with other nanoscale magnetic-field sensors, NV centres have the advantage that they can probe quantities that go beyond average magnetic fields. Leveraging techniques from magnetic resonance, NV centres can perform high-precision noise sensing and have given access to diverse systems, such as fluctuating electrical currents in simple metals and graphene, as well as magnetic dynamics in yttrium iron garnet. In this Technical Review, we provide an overview of NV sensing platforms and modalities and discuss the connections between specific NV measurements and important physical characteristics in condensed matter, such as correlation functions and order parameters, that are inaccessible by other techniques. We conclude with our perspectives on the new insights that may be opened up by NV sensing in condensed matter. Nitrogen vacancy centre quantum sensors are quantitative, non-invasive and physically robust probes of condensed matter systems that offer nanoscale resolution across a wide range of temperatures. This Technical Review discusses the connections between NV measurements and important physical characteristics in condensed matter.

用于多体物理的纳米级金刚石量子传感器
氮空位(NV)中心量子传感器为研究凝聚态系统提供了独特的机会,因为它们是定量的、非侵入性的、物理健壮的、提供纳米级分辨率的,并且可以在很宽的温度范围内使用。近年来,这些性质已被用于获得凝聚态体系中自旋顺序和电流产生的静态磁场的纳米级分辨率测量。与其他纳米级磁场传感器相比,NV中心的优势在于它们可以探测超出平均磁场的量。利用磁共振技术,NV中心可以进行高精度的噪声传感,并可以访问各种系统,例如简单金属和石墨烯中的波动电流,以及钇铁石榴石中的磁动力学。在本技术评论中,我们概述了NV传感平台和模式,并讨论了特定NV测量与凝聚态物质中重要物理特性之间的联系,例如相关函数和顺序参数,这些是其他技术无法实现的。我们总结了我们对可能在凝聚态物质中开启NV传感的新见解的观点。氮空位中心量子传感器是一种定量的、非侵入性的、物理上坚固的凝聚态系统探针,可在广泛的温度范围内提供纳米级分辨率。本技术评论讨论了NV测量与凝聚态物质重要物理特性之间的联系。
