Abstract
The nitrogen vacancy (NV) center in diamond is well known for its outstanding optical and spin properties, enabling various applications in quantum sensing and quantum information at both cryogenic and ambient temperatures. Despite a large body of work, however, the NV center's dynamics at intermediate temperatures are incompletely understood. This paper describes a basic rate model able to explain the NV population dynamics over the full parameter space of temperature, crystallographic strain, and magnetic field. Numerical simulations of the model are in excellent agreement with experiments discussed in the accompanying PRL.
