In one method, rotation of the NV− symmetry axis will induce Berry phase shifts in the NV− electronic ground-state coherences proportional to the solid angle subtended by the symmetry axis. A second method uses a modified Ramsey scheme where Berry phase shifts in the 14N hyperfine sublevels are employed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gyroscopes based on nitrogen-vacancy centers in diamond","description":"A solid-state gyroscope apparatus based on ensembles of negatively charged nitrogen-vacancy (NV−) centers in diamond and methods of detection are provided.
