Strongly correlated quantum spin liquid phases form when quantum fluctuations prevent magnetic ordering, which normally requires low spin systems that cannot be analyzed semiclassically. Here, the authors show that a large-spin Kitaev model supports

Honeycomb iridates are candidates for the realization of a Kitaev spin liquid, displaying properties such as the protection of quantum information. Here, the authors investigate the phase diagram of honeycomb Li2IrO3, using quantum chemistry methods

The spin-1/2 Heisenberg kagome antiferromagnet is one of the paradigmatic playgrounds for frustrated quantum magnetism, with an extensive number of competing resonating valence bond (RVB) states emerging at low energies, including gapped and gapless

We present a theoretical study of the response of β-Li_{2}IrO_{3} under external magnetic fields in the ab, bc, and ac crystallographic planes. The results are based on the minimal nearest-neighbor J-K-Γ model and reveal a rich intertwining of fiel

We present a unified description of the response of the hyperhoneycomb Kitaev magnet β−Li_{2}IrO_{3} to applied magnetic fields along the orthorhombic directions a, b, and c. This description is based on the minimal nearest-neighbor J−K−Γ mod

We show that the mesoscopic incommensurate Z_{2} vortex crystals proposed for layered triangular anisotropic magnets can be most saliently identified by two distinctive signatures in dynamical spin response experiments: the presence of pseudo-Goldsto

We show that the topological Kitaev spin liquid on the honeycomb lattice is extremely fragile against the second-neighbor Kitaev coupling K_{2}, which has recently been shown to be the dominant perturbation away from the nearest-neighbor model in iri

By ab initio many-body quantum chemistry calculations, we determine the strength of the symmetric anisotropy in the 5d^{5} j≈1/2 layered material Ba_{2}IrO_{4}. While the calculated anisotropic couplings come out in the range of a few meV, orders o
