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…
Confinement of Bose-Einstein magnon condensates in adjustable complex magnetization landscapes
Matthias R. Schweizer, Alexander J. E. Kreil, Georg von Freymann +2
Coherent wave states such as Bose-Einstein condensates (BECs), which spontaneously form in an overpopulated magnon gas even at room temperature, have considerable potential for wav…
Experimental observation of Josephson oscillations in a room-temperature Bose-Einstein magnon condensate
Alexander J. E. Kreil, Halyna Yu. Musiienko-Shmarova, Pascal Frey +5
The alternating current (ac) Josephson effect in a time-independent spatially-inhomogeneous setting is manifested by the occurrence of Josephson oscillations - periodic macroscopic…
Room temperature and low-field resonant enhancement of spin Seebeck effect in partially compensated magnets
R. Ramos, T. Hioki, Y. Hashimoto +7
Resonant enhancement of spin Seebeck effect (SSE) due to phonons was recently discovered in Y3Fe5O12 (YIG). This effect is explained by hybridization between the magnon and phonon…
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…
