Caloric Phenomena and Stirling-Cycle Performance in Heisenberg- Kitaev Magnon Systems
Bastian Castorene, Martin HvE Groves, Francisco J. Peña +5
We investigate the Stirling-cycle performance of a Heisenberg--Kitaev magnonic medium with Dzyaloshinskii--Moriya (DM) interactions. Using linear spin-wave theory, we show the DM i…
Antiferromagnetic Pure Spin Current Memdevices
Martin Latorre, Gaspar De la Barrera, Roberto E. Troncoso +1
Spin currents can be generated through various mechanisms, including the piezospintronic effect, which arises when strain or lattice distortions induce a change in the dipolar spin…
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…
Magnetic topological textures in nonorientable surfaces
Carlos Saji, Mario A. Castro, Vagson L. Carvalho-Santos +3
Topological magnetic textures confined to two-dimensional (2D) non-orientable manifolds exhibit behaviors absent in planar systems. We investigate bimerons on Möbius surfaces and s…
Electric-Field Control of Josephson Oscillations in Dipolar Bose-Einstein Condensates
David Galvez-Poblete, Roberto E. Troncoso, Guillermo Romero +2
We study the dynamic behavior of a Bose-Einstein condensate (BEC) with dipolar interactions when the influence of external electric fields affects the coherent tunneling properties…
