A theoretical overview of the phenomenon of spontaneous magnon decays in quantum
antiferromagnets is presented. The intrinsic zero-temperature dam** of magnons in …

The unconventional superconductor UTe 2 exhibits numerous signatures of spin-triplet
superconductivity—a rare state of matter which could enable quantum computation …

We elucidate the role of magnon interaction and spontaneous decays in the spin dynamics
of the triangular-lattice Heisenberg antiferromagnet by calculating its dynamical structure …

We propose a theory for thermal Hall transport mediated by magnons to address the impact
of their dam** resulting from magnon-magnon interactions in insulating magnets. This …

In quantum magnets, magnetic moments fluctuate heavily and are strongly entangled with
each other, a fundamental distinction from classical magnetism. Here, with inelastic neutron …

Topologically protected magnon surface states are highly desirable as an ideal platform to
engineer low-dissipation spintronics devices. However, theoretical prediction of topological …

We study the influence of nonlocal dam** on the magnon properties of Fe, Co, Ni, and Fe
1− x Co x (x= 30%, 50%) alloys. The Gilbert dam** parameter is typically considered as a …

We propose a theoretical framework to investigate elementary excitations at finite
temperatures within a localized electron model that describes the interactions between …

We calculate magnon dispersions and dam** in the Kitaev-Heisenberg model with an off-
diagonal exchange Γ and isotropic third-nearest-neighbor interact ion J 3 on a honeycomb …

We provide analytical and numerical insights into the phase diagram and other properties of
the extended Kitaev-Heisenberg model on the honeycomb lattice in the easy-plane limit, in …
