Enhancement of magnon flux toward a Bose-Einstein condensate
Franziska Kühn, Matthias R. Schweizer, Tamara Azevedo +5
We present a combined theoretical and experimental study of angle-dependent parametric pumping of magnons in Yttrium Iron Garnet films, with a focus on the mechanisms that transfer…
From Kinetic Instability to Bose-Einstein Condensation and Magnon Supercurrents
Alexander J. E. Kreil, Dmytro A. Bozhko, Halyna Yu. Musiienko-Shmarova +4
Evolution of an overpopulated gas of magnons to a Bose-Einstein condensate and excitation of a magnon supercurrent, propelled by a phase gradient in the condensate wave function, c…
Bottleneck accumulation of hybrid magneto-elastic bosons
Dmytro A. Bozhko, Peter Clausen, Gennadii A. Melkov +6
It is known that an ensemble of magnons, quanta of spin waves, can be prepared as a Bose gas of weakly interacting quasiparticles with conservation of the particle number. Furtherm…
Supercurrent in a room temperature Bose-Einstein magnon condensate
D. A. Bozhko, A. A. Serga, P. Clausen +6
We report evidence for the existence of a supercurrent of magnons in a magnon Bose-Einstein condensate prepared in a room temperature yttrium-iron-garnet magnetic film and subject…
Stimulated Thermalization of a Parametrically Driven Magnon Gas as a Prerequisite for Bose-Einstein Magnon Condensation
P. Clausen, D. A. Bozhko, V. I. Vasyuchka +3
Thermalization of a parametrically driven magnon gas leading to the formation of a Bose-Einstein condensate at the bottom of a spin-wave spectrum was studied by time- and wavevecto…
