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…

Configuration Interaction with Antisymmetrized Geminal Powers
Wataru Uemura, Shusuke Kasamatsu, Osamu Sugino
To avoid the combinatorial computational cost of configuration interaction (CI), we have previously introduced the symmetric tensor decomposition CI (STD-CI) method, where we take…

Symmetric Tensor Decomposition Description of Fermionic Many-Body Wavefunctions
Wataru Uemura, Osamu Sugino
The configuration interaction (CI) is a versatile wavefunction theory for interacting fermions but it involves an extremely long CI series. Using a symmetric tensor decomposition (…
