From: Pressure-driven collapse of the relativistic electronic ground state in a honeycomb iridate
A comparison of major pressure scales in α-Li2IrO3 identified by XAS, XRD, and RIXS. a Pressure dependence of the Ir L2 and L3 edge white line intensity obtained from XAS. b Pressure dependence of the Ir-Ir bond lengths determined from XRD. c Pressure dependence of the inelastic peak positions (or intra-t2g transition energies) determined from RIXS. The experimental data highlights four different regimes, which we attribute to: a localized Jeff = 1/2 state (unshaded), a localized pseudospin S = 1/2 state (shaded red), an itinerant QMO state (shaded green), and a highly distorted dimerized state (shaded blue)
