Dimensionality-strain phase diagram of strontium iridates
The competition between spin-orbit coupling, bandwidth $(W)$, and electron-electron interaction $(U)$ makes iridates highly susceptible to small external perturbations, which can trigger the onset of novel types of electronic and magnetic states. Here we employ first principles calculations based on density functional theory and on the constrained random phase approximation …
