We suggest that a randomization of the pseudodipolar interaction in the spin-orbit-generated
low-energy Hamiltonian of YbMgGaO 4 due to an inhomogeneous charge environment from …

Spin systems with frustrated anisotropic interactions are of significant interest due to
possible exotic ground states. We have explored their phase diagram on a nearest-neighbor …

A symmetry-based analysis (projective symmetry group) is used to study spin-liquid phases
on the triangular and Kagomé lattices in the Schwinger boson framework. A maximum of …

Motivated by the recent numerical evidence [Z. Meng, T. Lang, S. Wessel, F. Assaad, and A.
Muramatsu, Nature (London) 464, 847 (2010) 10.1038/nature08942] of a short-range …

We use the coupled cluster method (CCM) to study the zero-temperature ground-state (GS)
properties of a spin-1 2 J 1− J 2 Heisenberg antiferromagnet on a triangular lattice with …

We compute the zero-temperature dynamical structure factor S (q, ω) of the triangular lattice
Heisenberg model (TLHM) using a Schwinger boson approach that includes the Gaussian …

We study, within the Schwinger-boson approach, the ground-state structure of two
Heisenberg antiferromagnets on the triangular lattice: the J 1− J 2 model, which includes a …

Using the coupled cluster method (CCM) we study the zero-temperature phase diagram of a
spin-half Heisenberg antiferromagnet (HAF), the so-called J 1–J 2′ model, defined on an …

We study the ground-state phase diagram of the frustrated quantum J 1-J 2 Heisenberg
antiferromagnet on the honeycomb lattice using a mean-field approach in terms of the …

We study the phase diagram at T= 0 of the antiferromagnetic Heisenberg model on the
triangular lattice with spatially anisotropic interactions. For values of the anisotropy very …
