Seniority Eigenstate Configuration Interaction
Thomas M Henderson, Guo P. Chen, Gustavo E. Scuseria
Zero-seniority methods have shown great promise for the description of strongly-correlated electronic systems. Other seniority sectors have been much less explored, and in particul…
Jordan-Wigner Transformation for the Description of Strong Correlation in Fermionic Systems
Thomas M. Henderson, Guo P. Chen, Gustavo E. Scuseria
Seniority is a useful way of organizing Hilbert space for strongly correlated systems. The exact zero-seniority wave function, doubly-occupied configuration interaction (DOCI), pro…
Putting fermions onto a digital quantum computer
Riley W. Chien, Mitchell L. Chiew, Brent Harrison +8
Quantum computers are expected to become a powerful tool for studying physical quantum systems. Consequently, a number of quantum algorithms for studying the physical properties of…
SCF framework, HF stability and RPA correlation for Jordan-Wigner-transformed spin Hamiltonians on arbitrary coupling topologies
Shadan Ghassemi Tabrizi, Thomas M. Henderson, Thomas D. Kühne +1
Mapping spins to fermions via the Jordan-Wigner (JW) transformation can render mean-field (Hartree-Fock, HF) descriptions effective for strongly correlated spin systems. As establi…
Scalable implementations of mean-field and correlation methods based on Lie-algebraic similarity transformation of spin Hamiltonians in the Jordan-Wigner representation
Shadan Ghassemi Tabrizi, Thomas M. Henderson, Thomas D. Kühne +1
Recent work has highlighted that the strong correlation inherent in spin Hamiltonians can be effectively reduced by mapping spins to fermions via the Jordan-Wigner transformation (…
Symmetry-Projected Spin-AGP Methods Applied to Spin Systems
Zhiyuan Liu, Thomas M. Henderson, Gustavo E. Scuseria
Symmetry-projected wave function methods capture static correlation by breaking and restoring the symmetries of a system. In this article, we present the symmetry-projected spin an…
