Two recent theoretical works studied the role of Kitaev interactions in the newly observed incommensurate magnetic order in the hyper-honeycomb ($\ensuremath{\beta}\ensuremath{-}{\mathrm{Li}}_{2}{\mathrm{IrO}}_{3}$) and stripy-honeycomb ($\ensuremath{\gamma}\ensuremath{-}{\mathrm{Li}}_{2}{\mathrm{IrO}}_{3}$) iridates. Each of these works analyzed a different model ($JK\mathrm{\ensuremath{\Gamma}}$ versus coupled zigzag chain model) using a contrasting method (classical versus soft-spin analysis…

Heisenberg-Kitaev models on hyperhoneycomb and stripy-honeycomb lattices: 3D-2D equivalence of ordered states and phase diagrams
We discuss magnetically ordered states, arising in Heisenberg-Kitaev and related spin models, on three-dimensional (3D) harmonic honeycomb lattices. For large classes of ordered states, we show that
Electronic excitations in γ-Li2IrO3
We investigate the electronic properties of the three-dimensional stripyhoneycomb $\gamma$-Li$_2$IrO$_3$ via relativistic density functional theory calculations as well as exact diagonalization of

Nonsymmorphic-Symmetry-Protected Topological Magnons in Three-Dimensional Kitaev Materials.
It is shown that three-dimensional Kitaev materials with nonsymmorphic symmetries can provide a great opportunity for controlling symmetry-protected topological nodal magnons and how such topological magnons can be controlled by changing the symmetry of the underlying spin-exchange interactions.

Classification and properties of quantum spin liquids on the hyperhoneycomb lattice
The family of "Kitaev materials" provides an ideal platform to study quantum spin liquids and their neighboring magnetic orders. Motivated by the possibility of a quantum spin liquid ground state in
