Spin- $S$ 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- $S$ Kitaev-Heisenberg model on the honeycomb lattice for $S = 1/2$ , $1$ and $3/2$ , by using the coupled cluster method (CCM) of microscopic quantum many-body th…

Ground-State Ordering of the $J_{1}$ -- $J_{2}$ Model on the Simple Cubic and Body-Centered Cubic Lattices

D. J. J. Farnell, O. Götze, J. Richter

The $J_{1}$ -- $J_{2}$ 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…

Direct calculation of the spin stiffness on square, triangular and cubic lattices using the coupled cluster method

S. E. Krüger, R. Darradi, J. Richter +1

We present a method for the direct calculation of the spin stiffness by means of the coupled cluster method. For the spin-half Heisenberg antiferromagnet on the square, the triangu…
