Ellipticity effects on diffusive magnon spin and heat transport in easy-plane ferromagnets
Nicolas Vidal-Silva, Alejandro O. Leon
When a magnetic material hosts spin-wave excitations, or magnons, the local magnetization can rotate in circular or elliptical orbits, the latter arising naturally in the presence…
Scattering theory of spin waves by lattice dislocation defects
Cristobal Larronde, Ignacio Castro, Alvaro S. Nunez +2
We investigate spin-wave propagation in magnetic insulators in the presence of lattice dislocations. Within a continuum magnetoelastic framework, we show that the strain fields gen…
Transport of Dirac magnons driven by gauge fields
Luis Fernández, Ka Shen, Leandro O. Nascimento +3
We present a unified quantum field theory for Dirac magnons coupled to emergent gauge fields. At zero temperature, any space- and time-dependent gauge perturbation drives magnons o…
Theoretical Characterization of the Magnetic Properties of Vanadium-doped Ti2C MXenes
Carlos Patiño, Pablo DÃaz, Nicolás Vidal-Silva +3
MXenes are two-dimensional materials composed of transition metals and light elements, known for their high conductivity and versatile surface chemistry. The introduction of spin c…
Topological magnonic dislocations modes
Carlos Saji, Nicolas Vidal-Silva, Alvaro S. Nunez +1
Spin fluctuations in two-dimensional (2D) ferromagnets in the presence of crystalline lattice dislocations are investigated. We show the existence of topologically protected non-pr…
Magnons in the strained Heisenberg-Kitaev magnet
Miguel Letelier, Roberto E. Troncoso, Nicolas Vidal-Silva
The properties of magnons hosted in strained Heisenberg-Kitaev magnets are investigated using numerical and analytical calculations. Considering that deformation fields modulate th…
