Detection dead zones and heading errors induced by light shifts are two important problems in optically pumped scalar magnetometry. We introduce an atomic orientation based single-beam magnetometry scheme to simultaneously solve these problems, using a polarization-reversing and path-bending Herriott cavity. Here, a reflection mirror is inserted into the cavity to bend the optical paths in the middle, and divide them into two separated orthogonal regions to avoid the detection dead zone…

Recording brain activities in unshielded Earth’s field with optically pumped atomic magnetometers
TLDR
This work introduces an unshielded MEG system based on optically pumped atomic magnetometers, and builds an atomic magnetic gradiometer, together with feedback methods, to reduce the environment magnetic field noise.
Search for topological defect dark matter with a global network of optical magnetometers
TLDR
The search for transient signals from the domain walls of axion-like particles by using the global network of optical magnetometers for exotic (GNOME) physics searches finds no statistically significant signals, thus placing experimental constraints on such dark matter scenarios.
Spatial frequency isotropy of an optically pumped 4He magnetometer
