Hartree-Fock-Bogoliubov theory for number-parity--violating fermionic Hamiltonians
Thomas M. Henderson, Shadan Ghassemi Tabrizi, Guo P. Chen +1
It is usually asserted that physical Hamiltonians for fermions must contain an even number of fermion operators. This is indeed true in electronic structure theory. However, when t…
Robust formulation of Wick's theorem for computing matrix elements between Hartree-Fock-Bogoliubov wavefunctions
Guo P. Chen, Gustavo E. Scuseria
Numerical difficulties associated with computing matrix elements of operators between Hartree-Fock-Bogoliubov (HFB) wavefunctions have plagued the development of HFB-based many-bod…
Exploring Spin AGP Ansatze for Strongly Correlated Spin Systems
Zhiyuan Liu, Fei Gao, Guo P. Chen +3
The antisymmetrized geminal power (AGP), a wave function equivalent to number-projected Hartree--Fock--Bogoliubov (HFB), and number-projected Bardeen--Cooper--Schrieffer (BCS) when…
