Spontaneous Emergence of Phase Coherence in a quasiparticle Bose-Einstein Condensate
Malte Koster, Matthias R. Schweizer, Timo Noack +6
Since their prediction by Einstein at the dawn of quantum mechanics, Bose-Einstein condensates (BECs), owing to their property to show quantum phenomena on macroscopic scales, are…
Bose-Einstein condensation in systems with flux equilibrium
Victor S. L'vov, Anna Pomyalov, Sergey V. Nazarenko +4
We consider flux equilibrium in dissipative nonlinear wave systems subject to external energy pumping. In such systems, the elementary excitations, or quasiparticles, can create a…
Correlation-enhanced interaction of a Bose-Einstein condensate with parametric magnon pairs and virtual magnons
Victor S. L'vov, Anna Pomyalov, Dmytro A. Bozhko +2
Nonlinear interactions are crucial in science and engineering. Here, we investigate wave interactions in a highly nonlinear magnetic system driven by parametric pumping leading to…
Magnon Bose-Einstein condensate and supercurrents over a wide temperature range
L. Mihalceanu, D. A. Bozhko, V. I. Vasyuchka +5
Magnon Bose-Einstein Condensates (BECs) and supercurrents are coherent quantum phenomena, which appear on a macroscopic scale in parametrically populated solid state spinsystems. O…
Tunable space-time crystal in room-temperature magnetodielectrics
Alexander J. E. Kreil, Halyna Yu. Musiienko-Shmarova, Dmytro A. Bozhko +5
We report the experimental realization of a space-time crystal with tunable periodicity in time and space in the magnon Bose-Einstein Condensate (BEC), formed in a room-temperature…
Long-distance supercurrent transport in a room-temperature Bose-Einstein magnon condensate
Dmytro A. Bozhko, Alexander J. E. Kreil, Halyna Yu. Musiienko-Shmarova +4
The term supercurrent relates to a macroscopic dissipation-free collective motion of a quantum condensate and is commonly associated with such famous low-temperature phenomena as s…
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…
