- Abstract summary: We present an open source simulation tool that models the influence of arbitrary electric and magnetic fields on the electronic and nuclear spin states of NV ensembles.
Specifically, the code computes the transition strengths and predicts the sensitivity under shot-noise-limited optically-detected magnetic resonance.
We show that our code can be used to optimize sensitivity in situations where usual arguments based on neglecting terms in the full Hamiltonian would give sub-optimal results.

- Abstract: Solid state spins in diamond, in particular negatively charged
nitrogen-vacancy centers (NV), are leading contenders in the field of quantum
sensing. While addressing of single NVs offers nanoscale spatial resolution,
many implementations benefit from using large ensembles to increase signal
magnitude and therefore sensitivity. However, sensing with ensembles brings its
own challenges given the random orientation of the spin quantization axis
within the diamond crystal lattice. Here, we present an open source simulation
tool that models the influence of arbitrary electric and magnetic fields on the
electronic and nuclear spin states of NV ensembles, and can be extended to
other color centers. Specifically, the code computes the transition strengths
and predicts the sensitivity under shot-noise-limited optically-detected
magnetic resonance. We illustrate the use of the code in the context of
electric field sensing, a promising emerging functionality of NV centers with
applications in biosensing and electronics, and bring several subtle features
to light that are due to the interplay between different NV orientations and
the external electric and microwave fields. Moreover, we show that our code can
be used to optimize sensitivity in situations where usual arguments based on
neglecting terms in the full Hamiltonian would give sub-optimal results.
Finally, we propose a novel sensing scheme which allows to perform full vector
electrometry without the need for precise bias magnetic field alignment, thus
reducing the experimental complexity and speeding up the measurement procedure.
