The cradle of quantum spin liquids, triangular antiferromagnets show strong proclivity to
magnetic order and require deliberate tuning to stabilize a spin-liquid state. In this brief …

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 …

The description of quantized collective excitations stands as a landmark in the quantum
theory of condensed matter. A prominent example occurs in conventional magnets, which …

Co 2+ ions in an octahedral crystal field stabilize aj eff= 1/2 ground state with an orbital
degree of freedom and have been recently put forward for realizing Kitaev interactions, a …

The hexagonal RMnO3 (h-RMnO3) are multiferroic materials, which exhibit the coexistence
of a magnetic order and ferroelectricity. Their distinction is in their geometry that both results …

Abstract A spin-1/2 triangular-lattice Heisenberg antiferromagnet (TLHAF) is a prototypical
frustrated quantum magnet, which exhibits remarkable quantum many-body effects that arise …

Several tensor networks are built of isometric tensors, ie tensors satisfying $ W^\dagger
W=\mathrm {I} $. Prominent examples include matrix product states (MPS) in canonical form …

We study the Kitaev-Heisenberg Γ-Γ′ model that describes the magnetism in spin-orbit
coupled honeycomb lattice Mott insulators. In strong magnetic fields perpendicular to the …

We present single-crystal neutron scattering measurements of the spin-1/2 equilateral
triangular-lattice antiferromagnet Ba 3 CoSb 2 O 9. Besides confirming that the Co 2+ …
