The Gross-Pitaevskii equation (GPE) describing the dynamics of a Bose-Einstein condensate at absolute zero temperature, is a generalized form of the nonlinear Schr¨odinger equation. In this work, the exact bright one-soliton solution of the one-dimensional GPE with time-dependent parameters is directly obtained by using the well-known Hirota method under the same conditions as in S. Rajendran et al., Physica D 239, 366 (2010). In addition, the two-soliton solution is also constructed effectively

We experimentally demonstrate a magnon laser based on the coherent Bose–Einstein condensate of magnons brought into motion by using a time-dependent spatially inhomogeneous magnetic field. We show that the application of a short field pulse results in the formation of a condensate cloud moving with the constant velocity of 930 m/s for the used parameters of the experiment. The number of magnons building the cloud is not changed during the propagation, which is reminiscent of the magnon superfluidity.
