Anisotropic wavevector-dependent damping of thickness-quantized magnons
Tamara Azevedo, Rostyslav O. Serha, Yannik Kunz +7
Magnon damping is a key factor governing spin-wave transport and nonlinear dynamics of multimode magnon systems. However, many descriptions rely on the assumption of an effective m…
Bulk-mediated reflection of chirality-protected surface spin waves
Vitaliy I. Vasyuchka, Florin Ciubotaru, Andrii V. Chumak +2
Surface spin waves of the Damon-Eshbach type exhibit intrinsically nonreciprocal transport properties with a chiral dynamical field structure that localizes counterpropagating wave…
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…
Ultra-long-living magnons in the quantum limit
Rostyslav O. Serha, Kaitlin H. McAllister, Fabian Majcen +8
Solid-state platforms based on bosonic quasiparticles offer a compelling route toward on-chip quantum information technologies scalable to nanometer dimensions. Coherence time, a k…
Towards an experimental proof of the magnonic AharonovCasher effect
Rostyslav O. Serha, Vitaliy I. Vasyuchka, Alexander A. Serga +1
Controlling the phase and amplitude of spin waves in magnetic insulators with an electric field opens the way to fast logic circuits with ultra-low power consumption. One way to ac…
