Incipient and well-developed entropy plateaus in spin-S Kitaev models
J. Oitmaa, A. Koga, R. R. P. Singh
We present results on entropy and heat-capacity of the spin-S honeycomb-lattice Kitaev models using high-temperature series expansions and thermal pure quantum (TPQ) state methods.…
Efficient generation of series expansions for Ising spin-glasses in a classical or a quantum (transverse) field
R. R. P. Singh, A. P. Young
We discuss generation of series expansions for Ising spin-glasses with a symmetric (i.e. bimodal) distribution on d-dimensional hypercubic lattices using linked-cluster met…
Are multiphase competition & order-by-disorder the keys to understanding Yb2Ti2O7?
L. D. C. Jaubert, Owen Benton, Jeffrey G. Rau +4
If magnetic frustration is most commonly known for undermining long-range order, as famously illustrated by spin liquids, the ability of matter to develop new collective mechanisms…
Thermodynamic properties of the Yb2Ti2O7 pyrochlore as a function of temperature and magnetic field: validation of a quantum spin ice exchange Hamiltonian
N. R. Hayre, K. A. Ross, R. Applegate +3
The thermodynamic properties of the pyrochlore Yb2Ti2O7 material are calculated using the numericallinked-cluster (NLC) calculation method for an effective anisotropic-exchange spi…
Ground state properties, excitation spectra and phase transitions in the and 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 material BiMnONO, 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 Heisenberg models on the honeycomb lattice using series expansions around Néel and different co…
