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…
Non-magnetic insulating phase induced by Jahn-Teller effect in RNiO
Sangeeta Rajpurohit, Liang Z. Tan, Tadashi Ogitsu +1
We propose a three-dimensional multi-orbital tight-binding model for rare-earth nickelates RNiO that treats charge, spin, orbital, and lattice degrees of freedom on equal footi…
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…
The CP-PAW code package for first-principles calculations from a user's perspective
Peter E. Blöchl, Robert Schade, Lukas Allen-Rump +5
CP-PAW is a combined electronic structure and ab-initio molecular dynamics code to perform mixed quantum and classical simulations of atomistic condensed phase systems, such as sol…
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…
Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands
V. Moshnyaga, Ch. Jooss, P. E. Blöchl +12
Energy conversion in materials can be considered as a sequence of elementary steps initiated by a primary excitation. While these steps are quite well understood in classical semic…
