Coupled Cluster Greens function formulations based on the effective Hamiltonians
Nicholas P Bauman, Bo Peng, Karol Kowalski
We demonstrate that the effective Hamiltonians obtained with the downfolding procedure based on double unitary coupled cluster (DUCC) ansatz can be used in the context of Greens fu…
