Nonlinear Topological Orbital Responses of Antiferromagnetic Skyrmions
Amir N. Zarezad, Arne Brataas, Alireza Qaiumzadeh
Antiferromagnetic skyrmions evade the skyrmion Hall effect, but compensation suppresses their conventional topological charge Hall signal. We predict a semiclassical nonlinear topo…
Majorana interface states in anisotropic and tilted Dirac and Weyl systems
Abraham Kaleb Plascencia Pérez Páez, Alireza Qaiumzadeh
Anisotropy and cone tilt change how Majorana states propagate along an interface and decay away from it. We derive a two-dimensional Majorana surface Hamiltonian from a fully gappe…
Inherent electro-optic Kerr rotation
Erlend Syljuåsen, Alireza Qaiumzadeh, Rembert A. Duine +1
We uncover a previously overlooked contribution to the electro-optic Kerr rotation of reflected light, arising from the interplay of matter, the static electric field, and the magn…
Thickness-dependent magnon spin transport in antiferromagnetic insulators: Crossover from quasi-three-dimensional to quasi-two-dimensional regimes
Mathias Åsan Myhre, Verena Brehm, Thomas Delvaux +2
Motivated by the recent observation of giant room-temperature magnon spin conductivity in an ultrathin ferromagnetic insulator [X.-Y. Wei et al., Nat. Mater. 21, 1352 (2022)], we i…
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…
Phonon-enhanced optical spin-conductivity and spin-splitter effect in altermagnets
Erik Wegner Hodt, Alireza Qaiumzadeh, Jacob Linder
Collinear antiferromagnets with nonrelativistic spin-split bands and no net magnetization, called altermagnets, show interesting transport properties due to their unique band struc…
