Assess non-Stark mechanisms contributing to SnV spectral features

Determine whether strain or phononic mechanisms contribute to the observed spectral features of the SnV zero-phonon line under the reported experimental conditions, beyond DC-Stark shifts induced by local charges, and quantify their relative contributions to the measured spectra.

Background

The analysis and modeling in the paper interpret spectral dynamics primarily via DC-Stark shifts from local charge environments sensed by the inversion-symmetric SnV defect.

However, the authors explicitly acknowledge that other mechanisms such as strain or phononic effects cannot be ruled out, motivating a targeted investigation to confirm or refute additional contributions and to quantify their impact on spectral stability and coherence.

References

we cannot finally exclude any other mechanisms such as strain or phononic contributions, however, the experimental results and our model agree for a variety of local defect configurations, and we therefore conclude that our method is self-affirmative.
