Bichromatic light-induced electronic torques on the Néel vector in Rashba magnetic multipoles from -wave magnets to -wave altermagnets
Mohsen Yarmohammadi
Light can control magnetic order on ultrafast timescales, but for a two-dimensional magnet with an out-of-plane order parameter , the inverse Faraday…
Symmetry-selective nonrelativistic spin splitting in antiferromagnets driven by coherent phonons
Sangeeta Rajpurohit, Mohsen Yarmohammadi, Sheikh Rubaiat Ul Haque +3
Nonrelativistic spin splitting (NRSS) in antiferromagnets (AFMs) enables magnetization-free spin polarization for ultrafast spintronics. Here, we demonstrate that coherent phonons…
Anomalous dynamical energy flows via nonlinear phononics in spin-Peierls chains
Jakob Dolgner, Dirk Manske, James K. Freericks +1
We investigate the nonequilibrium spin-phonon dynamics and energy cascades in a strongly dimerized spin-Peierls chain using a multi-tiered nonlinear phononics architecture. To bypa…
Interplay of nonrelativistic and relativistic spin splittings in altermagnets
Daegeun Jo, Peter M. Oppeneer, Mohsen Yarmohammadi
Despite their compensated magnetic moments, altermagnets (AMs) exhibit nonrelativistic spin splitting (NRSS) that offers routes to spintronic functionality without relying on relat…
Parity-selective spin splitting in coplanar antiferromagnets via bichromatic driving
Di Zhu, Zhongbo Yan, Mohsen Yarmohammadi
Parity is a central characteristic of momentum-dependent spin splitting in antiferromagnets (AFMs). Yet, intrinsic crystal symmetries typically restrict the splitting to either eve…
Chirped Floquet linear drives activate forbidden charge-to-spin conversions in Rashba two-dimensional electron gases
Mohsen Yarmohammadi
In Rashba two-dimensional electron gases (2DEGs), charge-to-spin conversion via the Edelstein effect is conventionally limited to the transverse plane. Accessing longitudinal or ou…
Giant perpendicular Edelstein polarization in 2D compensated magnets via bichromatic Floquet driving
Mohsen Yarmohammadi, Daegeun Jo, Marco Berritta +3
While unconventional -wave magnets can generate nonrelativistic Edelstein polarizations, spin-group symmetries strictly forbid these responses in unconventional magnets with hig…
Floquet-induced anisotropic magnetoresistance and anomalous Hall effect in 2D -wave altermagnets with Rashba spin-orbit coupling
Mohsen Yarmohammadi, Pieter M. Gunnink, Jairo Sinova +1
Altermagnets (AMs) combine momentum-dependent spin splitting with zero net magnetization, making them promising for spintronics. Periodic driving enables dynamic symmetry engineeri…
Efficient two-color Floquet control of the RKKY interaction in altermagnets
Mohsen Yarmohammadi, Pei-Hao Fu, James K. Freericks
Magnetic impurities in real materials can mask the intrinsic spin-dependent properties of hosts. They interact indirectly through the Ruderman-Kittel-Kasuya-Yosida (RKKY) mechanism…
