Progress on the Global Network of Optical Magnetometers to search for Exotic physics (GNOME)

ORAL

Abstract

We discuss progress on the construction, implementation, and coordination of a network of geographically separated, time-synchronized ultrasensitive atomic magnetometers and comagnetometers to search for correlated transient signals heralding new physics. The {\textbf{G}}lobal {\textbf{N}}etwork of {\textbf{O}}ptical {\textbf{M}}agnetometers to search for {\textbf{E}}xotic physics (GNOME) is sensitive to nuclear and electron spin couplings to various exotic fields generated by astrophysical sources. A specific example of new physics detectable with the GNOME, presently unconstrained by previous experiments, is a network of domain walls of light pseudoscalar (axion-like) fields.
