Spin-orbital excitations encoding the magnetic phase transition in the van der Waals antiferromagnet FePS
Yuan Wei, Yi Tseng, Hebatalla Elnaggar +13
In the rich phases of van der Waals (vdW) materials featuring intertwined electronic order and collective phenomena, characterizing elementary dynamics that entail the low-energy H…
General expressions for Stevens and Racah operator equivalents
Octave Duros, Amélie Juhin, Hebatalla Elnaggar +2
Several definitions of the crystal field have been used over time and their variety has lead to many misunderstandings, in both theoretical and experimental literature. Two categor…
Nature of excitons and their ligand-mediated delocalization in nickel dihalide charge-transfer insulators
Connor A. Occhialini, Yi Tseng, Hebatalla Elnaggar +7
The fundamental optical excitations of correlated transition-metal compounds are typically identified with multielectronic transitions localized at the transition-metal site, such…
