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…

Terahertz field-induced giant symmetry modulations in a van der Waals antiferromagnet
Sheikh Rubaiat Ul Haque, Martin J. Cross, Sangeeta Rajpurohit +19
Strong-field terahertz (THz) excitations enable dynamic control over electronic, lattice and symmetry degrees of freedom in quantum materials. Here, we uncover pronounced terahertz…
