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…

Photoinduced orbital polarization and Jahn-Teller effect in RNiO
Sangeeta Rajpurohit, Sheikh Rubaiat Ul Haque, Aaron M. Lindenberg +2
The orbital degree of freedom in rare-earth nickelates is typically inactive across the temperature-driven metal-insulator transition, where the system develops two inequivalent Ni…
