- Abstract: Atom spin sensors occupy a prominent position in the scenario of quantum
technology, as they can combine precise measurements with appealing miniature
packages which are crucial for many applications. In this work, we report on
the design and realization of miniature silicon-wafer cells, with a
double-chamber configuration and integrated heaters. The cells are tested by
systematically studying the spin dynamics dependence on the main pump
parameters, temperature, and bias magnetic field. The results are benchmarked
against cm-sized paraffin-coated cells, which allows for optimisation of
operating conditions of a radio-frequency driven atomic magnetometer. In
particular, we observe that, when indirect optical pumping is performed on the
two cells, an analogous line narrowing mechanism appears in otherwise very
different cells' conditions. Competitive results are obtained, with magnetic
resonance linewidths of roughly 100 Hz at the maximum signal-to-noise ratio, in
a non-zero magnetic field setting, and in an atomic shot-noise limited regime.

In conditions of diffusive propagation, thermal atoms can potentially occupy various stable spatial modes in a glass cell.
We show that few of these modes can be selectively excited, manipulated, and interrogated in atomic thermal vapours using laser light.
Our results indicate that systematic engineering of the multi-mode nature of diffusive gases has great potential for improving the performance of quantum technology applications.
