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…
Spin polarization engineering in -wave altermagnets
Mohsen Yarmohammadi, Marco Berritta, Marin Bukov +3
Altermagnets host unconventional spin-polarized bands despite zero net magnetization, but controlling their spin structure remains challenging. We propose a multi-field approach to…
Slow-phonon control of spin Edelstein effect in Rashba -wave altermagnets
Mohsen Yarmohammadi, Jacob Linder, James K. Freericks
Altermagnets have zero net magnetization yet feature spin-split bands. Here, we investigate how slow lattice vibrations (phonons) influence both the intrinsic and externally induce…
Dynamical phase transition in a strongly hybridized phonon-triplon chain
Mohsen Yarmohammadi
We study a dimerized spin-1/2 chain, such as CuGeO, hosting triplon excitations coupled to optical phonons under weak terahertz laser driving. Both phonons and triplons weakly…
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…
Anisotropic light-tailored RKKY interaction in two-dimensional -wave altermagnets
Mohsen Yarmohammadi, Ulrich Zülicke, Jamal Berakdar +2
Altermagnets are known in spintronics for their intrinsic spin-splitting and unconventional magnetic responses, particularly to magnetic impurities. However, effectively controllin…
