Thermalization of magnons in yttrium-iron garnet: nonequilibrium functional renormalization group approach
Johannes Hick, Thomas Kloss, Peter Kopietz
Using a nonequilibrium functional renormalization group (FRG) approach we calculate the time evolution of the momentum distribution of a magnon gas in contact with a thermal phonon…

Bose-Einstein condensation at finite momentum and magnon condensation in thin film ferromagnets
Johannes Hick, Francesca Sauli, Andreas Kreisel +1
We use the Gross-Pitaevskii equation to determine the spatial structure of the condensate density of interacting bosons whose energy dispersion epsilon_k has two degenerate minima…
