Josephson Effects in a Bose-Einstein Condensate of Magnons
arXiv:1305.4285 · doi:10.1016/j.aop.2014.04.017
Abstract
A phenomenological theory is developed, that accounts for the collective dynamics of a Bose-Einstein condensate of magnons. In terms of such description we discuss the nature of spontaneous macroscopic interference between magnon clouds, highlighting the close relation between such effects and the well known Josephson effects. Using those ideas we present a detailed calculation of the Josephson oscillations between two magnon clouds, spatially separated in a magnonic Josephson junction.
