Ground state selection by magnon interactions in the fcc antiferromagnet

R. Schick, O. Götze, T. Ziman +3

We study the nearest-neighbor Heisenberg antiferromagnet on a face-centered cubic lattice with arbitrary spin S. The model exhibits degenerate classical ground states including two…

Frustrated spin- $\frac{1}{2}$ Heisenberg magnet on a square-lattice bilayer: High-order study of the quantum critical behavior of the $J_{1}$ -- $J_{2}$ -- $J_{1}^{⊥}$ model

R. F. Bishop, P. H. Y. Li, O. Götze +1

The zero-temperature phase diagram of the spin- $\frac{1}{2}$ $J_{1}$ -- $J_{2}$ -- $J_{1}^{⊥}$ model on an $AA$ -stacked square-lattice bilayer is studied using the coupled cluster…

Emergence of magnetic long-range order in kagome quantum antiferromagnets

Johannes Richter, Oliver Götze

The existence of a spin-liquid ground state of the $s = 1/2$ Heisenberg kagome antiferromagnet (KAFM) is well established. Meanwhile, also for the $s = 1$ Heisenberg KAFM evidence for…
