Theory of magnon hydrodynamics in collinear antiferromagnets
Vivianne Olguín-Arias, Alireza Qaiumzadeh, Roberto E. Troncoso
We investigate the transport of spin angular momentum and linear momentum carried by magnons in electrically insulating collinear antiferromagnets (AFs). Focusing on both transvers…
Stability of chiral magnon condensates in collinear antiferromagnetic insulators
Therese Frostad, Anne Louise Kristoffersen, Verena Brehm +3
Quasiequilibrium magnon Bose-Einstein condensates in ferromagnetic insulators have been a field of great interest, while condensation in antiferromagnetic systems has not yet been…
Chiral magnon-polaron edge states in Heisenberg-Kitaev magnets
Jose D. Mella, L. E. F. Foa Torres, Roberto E. Troncoso
The interplay of spin and lattice fluctuations in two-dimensional magnets without inversion symmetry is investigated. We find a general form for the magnetoelastic coupling between…
Robustness of topological magnons in disordered arrays of skyrmions
H. Diego Rosales, Roberto E. Troncoso
The effects of disorder on the robustness of topological magnon states of two-dimensional ferromagnetic skyrmions is investigated. It is diagnosed by evaluating a real space topolo…
Even-odd effect for spin current through thin antiferromagnetic insulator
Niklas Rohling, Roberto E. Troncoso
Magnon spin transport in a metal-antiferromagnetic insulator-ferromagnetic insulator heterostructure is considered. The spin current is generated via the spin Seebeck effect and in…
Magnonic Hall Effect and Magnonic Holography of Hopfions
Carlos Saji, Roberto E. Troncoso, Vagson L. Carvalho-Santos +2
Hopfions are localized and topologically non-trivial magnetic configurations that have received considerable attention in recent years. Through a micromagnetic approach, we analyze…
