Demystifying quantum escapism on the honeycomb lattice

A. L. Chernyshev

We demonstrate the versatility, simplicity, and power of the minimally-augmented spin-wave theory in studying phase diagrams of the quantum spin models in which unexpected magnetic…

BaCo $_{2}$ (AsO $_{4}$ ) $_{2}$ : Strong Kitaev, After All

Pavel A. Maksimov, Shengtao Jiang, L. P. Regnault +1

The inelastic neutron scattering results and their analysis unequivocally point to a dominant Kitaev interaction in the honeycomb-lattice cobaltate BaCo $_{2}$ (AsO $_{4}$ ) $_{2}$ . Our aniso…

Spontaneous magnon decays from nonrelativistic time-reversal symmetry breaking in altermagnets

Rintaro Eto, Matthias Gohlke, Jairo Sinova +3

Quasiparticles are central to condensed matter physics, but their stability can be undermined by quantum many-body interactions. Magnons, quasiparticles in quantum magnets, are par…

The Saga of $α$ -RuCl $_{3}$ : Parameters, Models, and Phase Diagrams

Marius Möller, P. A. Maksimov, Shengtao Jiang +3

RuCl $_{3}$ was likely the first ever deliberately synthesized ruthenium compound, following the discovery of the $_{44}$ Ru element in 1844. For a long time it was known as an oxidati…
