AbstractSearches for pseudo-magnetic spin couplings require implementation of techniques capable of sensitive detection of such interactions. While Spin-Exchange Relaxation Free (SERF) magnetometry is one of the most powerful approaches enabling the searches, it suffers from a strong magnetic coupling, deteriorating the pseudo-magnetic coupling sensitivity. To address this problem, here, we compare, via numerical simulations, the performance of SERF magnetometer and noble-gas-alkali-metal co-magnetometer, operating in a so-called self-compensating regime. We demonstrate that the co-magnetometer allows reduction of the sensitivity to low-frequency magnetic fields without loss of the sensitivity to nonmagnetic couplings. Based on that we investigate the responses of both systems to the oscillating and transient spin perturbations. Our simulations reveal about five orders of magnitude stronger response to the neutron pseudo-magnetic coupling and about three orders of magnitude stronger response to the proton pseudo-magnetic coupling of the co-magnetometer than those of the SERF magnetometer. Different frequency responses of the co-magnetometer to magnetic and nonmagnetic perturbations enables differentiation between these two types of interactions. This outlines the ability to implement the co-magnetometer as an advanced sensor for the Global Network of Optical Magnetometer for Exotic Physics searches (GNOME), aiming at detection of ultra-light bosons (e.g., axion-like particles).

In recent year, the sensitivities of atomic spin devices are improved greatly with the realization of spin exchange relaxation free (SERF) regime. Usually the SERF regime is realized using orthogonal beams scheme, i.e. one pump beam to polarize the atoms and the other orthogonal probe beam to measure the polarization. Due to the requirement of four optical windows for the atomic vapor cell, the orthogonal beams scheme has difficulties for micro fabrication. In this paper, we research a new scheme for SERF realization using only one beam, which facilitates the micro fabrication greatly. Furthermore, the fabrication processes of the MEMS atomic vapor cell with two out-of-plane optical windows are designed and performed. In the end, the possibility of increasing the relaxation time by nanotechnology is discussed.
