The hyperkagome iridate, ${\mathrm{Na}}_{4}{\mathrm{Ir}}_{3}{\mathrm{O}}_{8}$, has been regarded as a promising candidate material for a three-dimensional quantum spin liquid. Here the three-dimensional network of corner-sharing triangles forms the hyperkagome lattice of ${\mathrm{Ir}}^{4+}$ ions. Due to strong spin-orbit coupling, the local moments of ${\mathrm{Ir}}^{4+}$ ions are described by the pseudospin ${j}_{\mathrm{eff}}=1/2$ Kramers doublet. The Heisenberg model on this lattice is…
