Spectroscopic evidence for electron-boson coupling in electron-doped Sr${}_2$IrO${}_4$

Yong Hu, Xiang Chen, S. -T. Peng +15

The pseudogap, d-wave superconductivity and electron-boson coupling are three intertwined key ingredients in the phase diagram of the cuprates. Sr${}_2$IrO${}_4$ is a 5d-electron count…
