Spectroscopic Evidence for Electron-Boson Coupling in Electron-Doped Sr2IrO4

The pseudogap, d-wave superconductivity and electron-boson coupling are three intertwined key ingredients in the phase diagram of the cuprates. Sr2IrO4 is a 5d-electron counterpart of the cuprates in which both the pseudogap and a d-wave instability have been observed. Here, we report spectroscopic...
