Experiments in the time domain allow to determine the electron-boson coupling by determining the second moment of the Eliashberg function $\alpha^2F(\omega)$ from the relaxation time constant of thermalized, hot electrons after optical excitation due to energy dissipation into further degrees of freedom. While this approach works well for conventional superconducting materials, it is under...
