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…

Quantum geometry and magnon Hall transport in an altermagnet

Erlend Syljuåsen, Alireza Qaiumzadeh, Asle Sudbø

We compute magnon Hall conductivities in a minimal model of a two-dimensional altermagnet. To do so, we derive an analytic expression for the relevant quantum geometric tensor desc…

Magnon and photon blockade in a hybrid antiferromagnet-cavity quantum system

Vemund Falch, Arne Brataas, Alireza Qaiumzadeh

We investigate both magnon and photon blockade for an antiferromagnetic insulator coupled to a linearly polarized cavity mode. We focus on the cross-Kerr nonlinearity between the t…
