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 …
We demonstrate that interactions can substantially undermine the free-particle description of magnons in ferromagnets on geometrically frustrated lattices. The anharmonic coupling …

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 …
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 …
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 …

Recently, both experimental and theoretical advances have demonstrated that two- dimensional conjugated metal–organic frameworks (2D-cMOFs) exhibit interesting …
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 …
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 …
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 …
