Microscopic spin-wave theory for yttrium-iron garnet films
Andreas Kreisel, Francesca Sauli, Lorenz Bartosch +1
Motivated by recent experiments on thin films of the ferromagnetic insulator yttrium-iron garnet (YIG), we have developed an efficient microscopic approach to calculate the spin-wa…

Probing Anomalous Longitudinal Fluctuations of the Interacting Bose Gas via Bose-Einstein Condensation of Magnons
Andreas Kreisel, Nils Hasselmann, Peter Kopietz
The emergence of a finite staggered magnetization in quantum Heisenberg antiferromagnets subject to a uniform magnetic field can be viewed as Bose-Einstein condensation of magnons.…
