Spin- Kitaev-Heisenberg model on the honeycomb lattice: A high-order treatment via the many-body coupled cluster method
Marios Georgiou, Ioannis Rousochatzakis, Damian J. J. Farnell +2
We study the spin- Kitaev-Heisenberg model on the honeycomb lattice for , and , by using the coupled cluster method (CCM) of microscopic quantum many-body th…
Investigation of entanglement measures across the magnetization process of a highly frustrated spin-1/2 Heisenberg octahedral chain as a new paradigm of the localized-magnon approach
Jozef Strecka, Olesia Krupnitska, Johannes Richter
The bipartite entanglement across the magnetization process of a highly frustrated spin-1/2 Heisenberg octahedral chain is examined within the concept of localized magnons, which e…
Thermodynamics of delta-chain with ferro- and antiferromagnetic interactions
D. V. Dmitriev, V. Ya. Krivnov, J. Richter +1
Motivated by a novel cyclic compound with record ground state spin in which the arrangement of magnetic ions with and corresponds t…
Comment on `Oxygen vacancy-induced magnetic moment in edge-sharing CuO chains of LiCuO'
R. O. Kuzian, R. Klingeler, W. E. A. Lorenz +23
In a recent work devoted to the magnetism of LiCuO, Shu et al. [New J. Phys. 19 (2017) 023026] have proposed a "simplified" unfrustrated microscopic model that differs…
Thermodynamics of frustrated ferromagnetic spin- Heisenberg chains: The role of inter-chain coupling
P. Müller, J. Richter, D. Ihle
The thermodynamics of coupled frustrated ferromagnetic chains is studied within a spin-rotation-invariant Green's function approach. We consider an isotropic Heisenberg spin-half s…
Ground-State Ordering of the -- Model on the Simple Cubic and Body-Centered Cubic Lattices
D. J. J. Farnell, O. Götze, J. Richter
The -- Heisenberg model is a "canonical" model in the field of quantum magnetism in order to study the interplay between frustration and quantum fluctuations as well as q…
