Magnon pair emission from a relativistic domain wall in antiferromagnets
Magnon emission and excitation by a relativistic domain wall at a constant velocity in antiferromagnets is theoretically studied. A pair emission due to a quadratic magnon coupling is shown to be dominant. The emission corresponds in the comoving frame to a vacuum polarization induced by a zero-ener...
