High temperature series expansion study of the Heisenberg antiferromagnet on the hyperkagome lattice: Comparison with Na $_{4}$ Ir $_{3}$ O $_{8}$

R. R. P. Singh, J. Oitmaa

We develop high temperature series expansions for $ln Z$ and the uniform structure factor of the spin-half Heisenberg model on the hyperkagome lattice to order $β^{16}$ . These ex…

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…

A Frustrated 3-Dimensional Antiferromagnet: Stacked $J_{1} - J_{2}$ Layers

Onofre Rojas, C. J. Hamer, J. Oitmaa

We study a frustrated 3D antiferromagnet of stacked $J_{1} - J_{2}$ layers. The intermediate 'quantum spin liquid' phase, present in the 2D case, narrows with increasing interlayer cou…
