It is well known that the spontaneous breaking of discrete symmetries may lead to conflict with big-bang cosmology. This is due to formation of domain walls which give unacceptable contribution to the energy density of the universe. On the other hand it is expected that gravity breaks global symmetries explicitly. In this work we propose that this could provide a natural solution to the domain-wall problem.

Imprint of matter-antimatter asymmetry on collapsing domain walls
Radiative corrections from an asymmetric Dirac fermion generate a bias that collapses domain walls, producing gravitational waves that encode the asymmetry level and temperature.
