Revisiting magnon bound states: ferro-antiferromagnetic square-lattice model
Cesar A. Gallegos, A. L. Chernyshev
A comprehensive analysis of pairing and bound states of magnons in the Heisenberg square-lattice ferro-antiferromagnetic model is presented. We highlight…
Dynamics and thermodynamics of the S = 5/2 almost Heisenberg triangular lattice antiferromagnet K2Mn(SeO3)2
Mengze Zhu, V. Romerio, D. Moser +7
We report calorimetric, magnetic, and neutron scattering studies on an S = 5/2, nearly Heisenberg triangular-lattice antiferromagnet K2Mn(SeO3)2 with weak XXZ easy-axis anisotropy.…
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(AsO): 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(AsO). 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 -RuCl: Parameters, Models, and Phase Diagrams
Marius Möller, P. A. Maksimov, Shengtao Jiang +3
RuCl was likely the first ever deliberately synthesized ruthenium compound, following the discovery of the Ru element in 1844. For a long time it was known as an oxidati…
