Abstract Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can form stable, macroscopic field configurations in the of topological defects that could concentrate matter density into many distinct, compact spatial regions small compared with Galaxy but much larger than Earth. Here we report results search transient signals from domain walls by using global network optical magnetometers exotic (GNOME) physics searches. We data, consisting correlated...
Ultralight bosonic dark matter (UBDM) can be described by a classical wave-like field oscillating near the Compton frequency of bosons. If measurement scheme for direct detection UBDM interactions is sensitive to signature quadratic in field, then there near-zero-frequency (dc) component signal. Thus, detector with given finite bandwidth used search bosons frequencies many orders magnitude larger than its bandwidth. This opens possibility analogous Hanbury Brown and Twiss intensity...
The Global Network of Optical Magnetometers to search for Exotic physics (GNOME) is a network geographically separated, time-synchronized, optically pumped atomic magnetometers that being used correlated transient signals heralding exotic physics. GNOME sensitive nuclear- and electron-spin couplings fields from astrophysical sources such as compact dark-matter objects (for example, axion stars domain walls). Properties the sensors sensitivity, bandwidth, noise characteristics are studied in...
Abstract Numerous observations suggest that there exist undiscovered beyond‐the‐standard‐model particles and fields. Because of their unknown nature, these exotic fields could interact with standard model in many different ways assume a variety possible configurations. Here, an overview the global network optical magnetometers for physics searches (GNOME), ongoing experimental program designed to test wide range scenarios, is presented. The GNOME experiment utilizes worldwide shielded atomic...

Abstract Results are reported from the first full-scale search for transient signals exotic fields of astrophysical origin using data a newly constructed Earth-scale detector: Global Network Optical Magnetometers Exotic physics searches (GNOME). Data collected by GNOME consist correlated measurements optical atomic magnetometers located in laboratories all over world. searched patterns propagating through network consistent with composed ultralight bosons such as axion-like particles (ALPs)....
We present an analysis method to search for exotic low-mass field (ELF) bursts generated during large energy astrophysical events such as supernovae, binary black hole or neutron star mergers, and fast radio using the Global Network of Optical Magnetometers Exotic physics searches (GNOME). In our model, associated gravitational waves electromagnetic signals herald arrival ELF burst that interacts via coupling spin fermions in magnetometers. This enables GNOME serve a tool multi-messenger...
