Relaxation of Bose-Einstein Condensates of Magnons in Magneto-Textural Traps in Superfluid ${}^3$He-B

P. J. Heikkinen, S. Autti, V. B. Eltsov +3

In superfluid ${}^3$He-B externally pumped quantized spin-wave excitations or magnons spontaneously form a Bose-Einstein condensate in a 3-dimensional trap created with the order-par…
