Abstract = {{In so-called j(eff) = 1/2 systems, including some iridates and
   ruthenates, the coherent superposition of t(2g) orbitals in the ground
   state gives rise to hopping processes that strongly depend on the bond
   geometry. Resonant inelastic X-ray scattering measurements on CaIrO3
   reveal a prototypical j(eff) = 1/2 pseudospinon continuum, a hallmark of
   one-dimensional (1D) magnetic systems despite its three-dimensional
   crystal structure. The experimental spectra compare very well to the
   calculated magnetic dynamical structure factor of weakly coupled
   spin-1/2 chains. We attribute the onset of such quasi-1D magnetism to
   the fundamental difference in the magnetic interactions between the
   j(eff) = 1/2 pseudospins along the corner- and edge-sharing bonds in
   CaIrO3.}},
