Anisotropic Coulomb exchange as source of Kitaev and off-diagonal symmetric anisotropic couplings
Pritam Bhattacharyya, Thorben Petersen, Nikolay A. Bogdanov +1
Exchange underpins the magnetic properties of quantum matter. In its most basic form, it occurs through the interplay of Pauli's exclusion principle and Coulomb repulsion, being re…

Sweet spot in the RuCl magnetic system: nearly ideal moments and maximized ratio under pressure
Pritam Bhattacharyya, Liviu Hozoi, Quirin Stahl +2
Maximizing the ratio between Kitaev and residual Heisenberg interactions is a major goal in nowadays research on Kitaev-Heisenberg quantum magnets. Here we investigate Kitaev-Heise…
