Series expansion studies of the --Heisenberg bilayer
Erik Wagner, Wolfram Brenig
We study a bilayer of the frustrated - Heisenberg-model on the square lattice. Starting from the dimer limit at strong interlayer coupling, we perform series expansions u…

Two-triplon excitations of the Kitaev-Heisenberg-Bilayer
Erik Wagner, Wolfram Brenig
We study the spectrum of a bilayer of Kitaev magnets on the honeycomb lattice, coupled by Heisenberg exchange in the quantum-dimer phase at strong interlayer coupling. Using the pe…

Bilayer Kitaev models: Phase diagrams and novel phases
Urban F. P. Seifert, Julian Gritsch, Erik Wagner +4
Kitaev's honeycomb-lattice spin- model has become a paradigmatic example for quantum spin liquids, both gapped and gapless. Here we study the fate of these spin…
