Ground state properties, excitation spectra and phase transitions in the $S = 1/2$ and $S = 3/2$ bilayer Heisenberg models on the honeycomb Lattice

J. Oitmaa, R. R. P. Singh

Motivated by the observation of a disordered spin ground state in the $S = 3/2$ material Bi $_{3}$ Mn $_{4}$ O $_{12}$ NO $_{3}$ , we study the ground state properties and excitation spectra of th…

Phase Diagram of the J1, J2, J3 Heisenberg Models on the Honeycomb Lattice: A Series Expansion Study

J. Oitmaa, R. R. P. Singh

We study magnetically ordered phases and their phase boundaries in the $J_{1} - J_{2} - J_{3}$ Heisenberg models on the honeycomb lattice using series expansions around Néel and different co…
