Cavity-induced coherent magnetization and polaritons in altermagnets
Mohsen Yarmohammadi, Libor Šmejkal, James K. Freericks
Altermagnets feature antiparallel spin sublattices with -, -, or -wave spin order, yielding nonrelativistic spin splitting without net magnetization. We show that embeddin…

Cavity-assisted magnetization switching in a quantum spin-phonon chain
Mohsen Yarmohammadi, Peter M. Oppeneer, James K. Freericks
We propose a Néel magnetization switching mechanism in a hybrid magnon-phonon optical cavity system. A terahertz-pumped single-mode cavity photon couples to a spin-phonon chain, wh…
