Role of GNOME in dark-matter searches

We present a novel scheme for exotic-interaction searches. The scheme enables detection of short-time interaction between spins and other objects, whose signatures in traditional studies are buried in noise or cannot be singled out from instrumental artifacts. These short signals may, for example, arise, when spins interact with a jet of exotic particles or go through a non-uniform scalar field. It is shown that their detection is possible with synchronous measurements of readouts of at least five spatially separated devices, whose readouts are correlated. The application of a new scheme is demonstrated based on an example of Global Network of Optical Magnetometers for Exotic physics (GNOME).
