University College Cork (UCC) & University of Oxford Professor of Physics, Séamus Davis, has led a team of experimental physicists in the discovery of the magnetic noise generated by a fluid of magnetic monopoles.  There are two sound velocities in a Bose-Einstein condensate. In addition to the normal sound propagation there is second sound, which is a quantum phenomenon.  Quantum sensors can reach sensitivities that are impossible according to the laws of conventional physics that govern everyday life.
