Abstract

We propose solid-state gyroscopes based on ensembles of negatively charged nitrogen-vacancy () centers in diamond. In one scheme, rotation of the nitrogen-vacancy symmetry axis will induce Berry phase shifts in the electronic ground-state coherences proportional to the solid angle subtended by the symmetry axis. We estimate sensitivity in the range of in a 1 sensor volume using a simple Ramsey sequence. Incorporating dynamical decoupling to suppress dipolar relaxation may yield sensitivity at the level of . With a modified Ramsey scheme, Berry phase shifts in the hyperfine sublevels would be employed. The projected sensitivity is in the range of , however the smaller gyromagnetic ratio reduces sensitivity to magnetic-field noise by several orders of magnitude. Reaching would represent an order of magnitude improvement over other compact, solid-state gyroscope technologies.
