Configuration interaction extension of AGP for incorporating inter-geminal correlations
Airi Kawasaki, Fei Gao, Gustavo E. Scuseria
In this paper, we develop a class of antisymmetrized geminal power configuration interaction (AGP-CI) wave functions that extend the AGP framework by incorporating inter-geminal co…
Efficient Optimization of Low-Rank Antisymmetric Product of Geminals Wavefunction Using the Direct Givens Rotation Method
Airi Kawasaki, Rei Oshima, Naoki Nakatani +1
In our previous study, we proposed the low-rank antisymmetric product of geminals (APG) method, which reconstructs the wavefunction by extracting only the important eigenvalues fro…
Low-rank decomposition on the antisymmetric product of geminals for strongly correlated electrons
Airi Kawasaki, Naoki Nakatani
We investigated some variational methods to compute a wavefunction based on antisymmetric product of geminals (APG). The Waring decomposition on the APG wavefunction leads a finite…
Tensor decomposition methods for correlated electron pairs
Airi Kawasaki, Osamu Sugino
We analyze wave functions constructed as a sum of product of two-electron functions, or as a polynomial of geminals, to investigate their ability to represent the ground state of a…
Four-body correlation embedded in antisymmetrized geminal power wave function
Airi Kawasaki, Osamu Sugino
We extend the Coleman's antisymmetrized geminal power (AGP) to develop a wave function theory that can incorporate up to four-body correlation in a region of strong correlation. To…
