Real-Time Coupled-Cluster Approach for the Cumulant Green’s Function

Green’s function methods within many-body perturbation theory provide a general framework for treating electronic correlations in excited states and spectra. Here, we develop the cumulant form of the one-electron Green’s function using a real-time coupled-cluster equation-of-motion approach, in an e...
