The hydrogen atoms between its layers are disordered, and it is unclear whether its state is a Kitaev spin liquid altered by random couplings or a collection of random spin pairs unrelated to Kitaev physics.","posed_since":"2018","precise":"In $\\mathrm{H_3LiIr_2O_6}$ (no magnetic order detected down to tens of mK, $C/T$ diverging at low $T$ with $H/T$ scaling), determine whether the low-energy density of states and the scaling of $C/T$ arise from random Majorana hopping and fluxes bound to vacancies in a Kitaev spin liquid (Knolle, Moessner, Perkins, PRL 2019), or from random singlets of local moments without Kitaev fractionalization. An answer identifies the ground state with measured and calculated low-energy density of states agreeing within errors.","problem_ref":"d146d8be4c04adaf4a58a612a3ded5630d9b6bc0d1d38bf6288de976288a5f6e","references":"","settled_by":"Thermal conductivity, NMR and neutron spectroscopy on samples with controlled hydrogen or deuterium stacking disorder, compared with Kitaev-model simulations that include the measured bond disorder.","status_note":"Kitagawa et al.
