We recently proposed a novel approach to converging electronic energies equivalent high-level coupled-cluster (CC) computations by combining the deterministic CC(P;Q) formalism with stochastic configuration interaction (CI) and CC Quantum Monte Carlo (QMC) propagations. This article extends our initial study [J. E. Deustua, J. Shen, P. Piecuch, Phys. Rev. Lett. 119, 223003 (2017)], which focuse...
