“Stable domain walls of light (pseudo)scalar fields permeating the entire Universe and persisting to the present epoch is a generic consequence of many extensions to the Standard Model. Currently the combination of gravitational and cosmological constraints provides the best limits on such a possibility. We show that if domain walls are generated by an axion-like field with a coupling to the spins of standard-model particles, and the galactic environment contains a network of such walls, terrestrial experiments aimed at detection of wall-crossing events are realistic.”
