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…
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…
Local temperature control of magnon frequency and direction of supercurrents in a magnon Bose-Einstein condensate
Matthias R. Schweizer, Franziska Kühn, Victor S. L'vov +4
The creation of temperature variations in magnetization, and hence in the frequencies of the magnon spectrum in laser-heated regions of magnetic films, is an important method for s…
Dimensional Crossover in a Quantum Gas of Light
Kirankumar Karkihalli Umesh, Julian Schulz, Julian Schmitt +3
The dimensionality of a system profoundly influences its physical behaviour, leading to the emergence of different states of matter in many-body quantum systems. In lower dimension…
Rapid-prototyping of microscopic thermal landscapes in Brillouin light scattering spectroscopy
Matthias R. Schweizer, Franziska Kühn, Malte Koster +3
Since temperature and its spatial and temporal variations affect a wide range of physical properties of material systems, they can be used to create reconfigurable spatial structur…
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…
