摘要

This article presents the spatial transport of magnon Bose-Einstein condensate (mBEC) from their excitation region. It is shown that at a magnon density sufficient to BEC formation, a flow of coherent magnons is formed, analogous to the spatial flow of atoms in the BEC state, known as an atomic laser. We successfully reproduced the magnon laser effect, which is largely analogous to an atomic laser. However, unlike an atomic laser, a magnon laser also generates coherent polariton radiation, which we also observed. This new mechanism of coherent radiation and transport opens up new prospects for quantum applications.
