Constructing “Full-Frequency” Spectra via Moment Constraints for Coupled Cluster Green’s Functions
[Image: see text] We propose an approach to build “full-frequency” quasiparticle spectra from conservation of a set of static expectation values. These expectation values define the moments of the spectral distribution, resulting in an efficient and systematically improvable expansion. By computing...
