I Rousochatzakis, NB Perkins, Q Luo… - Reports on Progress in …, 2024 - iopscience.iop.org
We review the recent advances and current challenges in the field of strong spin-orbit
coupled Kitaev materials, with a particular emphasis on the physics beyond the exactly …

Strongly correlated flat-band systems: The route from Heisenberg spins to Hubbard electrons

O Derzhko, J Richter, M Maksymenko - International Journal of …, 2015 - World Scientific
On a large class of lattices (such as the sawtooth chain, the kagome and the pyrochlore
lattices), the quantum Heisenberg and the repulsive Hubbard models may host a completely …

Damped topological magnons in the kagome-lattice ferromagnets

AL Chernyshev, PA Maksimov - Physical review letters, 2016 - APS
We demonstrate that interactions can substantially undermine the free-particle description of
magnons in ferromagnets on geometrically frustrated lattices. The anharmonic coupling …

Highly degenerate ground states in a frustrated antiferromagnetic kagome lattice in a two-dimensional metal–organic framework

M Hua, B Xia, M Wang, E Li, J Liu, T Wu… - The Journal of …, 2021 - ACS Publications
Realization of the Kagome antiferromagnetic (KAF) lattice is of high interest because the
geometric frustration in the Kagome lattice is expected to give rise to highly degenerated …

Topological thermal Hall effect in frustrated kagome antiferromagnets

SA Owerre - Physical Review B, 2017 - APS
In frustrated magnets the Dzyaloshinsky-Moriya interaction (DMI) arising from spin-orbit
coupling can induce a magnetic long-range order. Here, we report a theoretical prediction of …

Static and dynamical spin correlations of the random-bond antiferromagnetic Heisenberg model on the triangular and kagome lattices

T Shimokawa, K Watanabe, H Kawamura - Physical Review B, 2015 - APS
Inspired by the recent theoretical suggestion that the random-bond S= 1/2 antiferromagnetic
Heisenberg model on the triangular and the kagome lattices might exhibit a randomness …

On-Surface Synthesis: A New Route Realizing Single-Layer Conjugated Metal–Organic Structures

J Liu, M Abel, N Lin - The Journal of Physical Chemistry Letters, 2022 - ACS Publications
Recently, both experimental and theoretical advances have demonstrated that two-
dimensional conjugated metal–organic frameworks (2D-cMOFs) exhibit interesting …

Frustration-induced emergent Hilbert space fragmentation

K Lee, A Pal, HJ Changlani - Physical Review B, 2021 - APS
Although most quantum systems thermalize locally on short timescales independent of initial
conditions, recent developments have shown this is not always the case. Lattice geometry …

Damped topological magnons in honeycomb antiferromagnets

QH Chen, FJ Huang, YP Fu - Physical Review B, 2023 - APS
We study magnon excitations and their interactions in honeycomb antiferromagnets with the
Dzyaloshinskii-Moriya interaction. When an applied magnetic field is turned on, the classical …

Classical spin liquid instability driven by off-diagonal exchange in strong spin-orbit magnets

I Rousochatzakis, NB Perkins - Physical review letters, 2017 - APS
We show that the off-diagonal exchange anisotropy drives Mott insulators with strong spin-
orbit coupling to a classical spin liquid regime, characterized by an infinite number of ground …
