(a) Simulated real part of self-energy at different energy resolutions. Four modes at 25, 40, 60, and 80 meV are assumed in and an impurity term 100 meV is added in the imaginary part of self-energy. The inset shows the measured for LSCO (solid squares), our fitted curve (red line) and Valla’s simulated curve at 18 meV energy resolution (blue line). (b) Second derivative of the simulated at different energy resolutions. The inset shows a Lorentzian (black) and its second derivative (red).Reuse & Permissions
