- Authors: Hans Marin Florez and Tadas Pyragius
- Abstract summary: We present theoretical description of Voigt and Faraday effect based optically pumped magnetometers using the Floquet expansion.
Our analysis describes the spin-operator dynamics of the first, $hatF(t)$, and second, $hatF(t)$, order moments and takes into account of different pumping profiles and decoherence effects.

- Abstract: We present theoretical description of Voigt and Faraday effect based
optically pumped magnetometers using the Floquet expansion. Our analysis
describes the spin-operator dynamics of the first, $\hat{F}(t)$, and second,
$\hat{F}^2(t)$, order moments and takes into account of different pumping
profiles and decoherence effects. We find that the theoretical results are in
good agreement with the experimental demonstrations over a wide range of fields
and pumping conditions. Finally, the theoretical analysis presented here is
generalized and can be extended to different magnetometry schemes with
arbitrary pumping profiles and multiple radio-frequency fields.
