Projected Coupled Cluster Theory: Optimization of cluster amplitudes in the presence of symmetry projection
Yiheng Qiu, Thomas M. Henderson, Jinmo Zhao +1
Methods which aim at universal applicability must be able to describe both weak and strong electronic correlation with equal facility. Such methods are in short supply. The combina…
Tensor-Structured Coupled Cluster Theory
Roman Schutski, Jinmo Zhao, Thomas M. Henderson +1
We derive and implement a new way of solving coupled cluster equations with lower computational scaling. Our method is based on decomposition of both amplitudes and two electron in…
Projected Coupled Cluster Theory
Yiheng Qiu, Thomas M. Henderson, Jinmo Zhao +1
Coupled cluster theory is the method of choice for weakly correlated systems. But in the strongly correlated regime, it faces a symmetry dilemma, where it either completely fails t…
Merging symmetry projection methods with coupled cluster theory: Lessons from the Lipkin model Hamiltonian
Jacob M Wahlen-Strothman, Thomas M. Henderson, Matthew R. Hermes +5
Coupled cluster and symmetry projected Hartree-Fock are two central paradigms in electronic structure theory. However, they are very different. Single reference coupled cluster is…
Polynomial Similarity Transformation Theory: A smooth interpolation between coupled cluster doubles and projected BCS applied to the reduced BCS Hamiltonian
Matthias Degroote, Thomas M. Henderson, Jinmo Zhao +2
We present a similarity transformation theory based on a polynomial form of a particle-hole pair excitation operator. In the weakly correlated limit, this polynomial becomes an exp…
Composite fermion-boson mapping for fermionic lattice models
Jinmo Zhao, Carlos A. Jimenez-Hoyos, Gustavo E. Scuseria +4
We present a mapping of elementary fermion operators onto a quadratic form of composite fermionic and bosonic operators. The mapping is an exact isomorphism as long as the physical…
