Approaching the Full Configuration Interaction Low-Energy Spectrum from an Arbitrary Reference Subspace
Carlos A. Jiménez-Hoyos
In a previous work (arXiv:2010.02027) we showed how the full configuration interaction (FCI) ground state energy can be obtained as a functional of an arbitrary reference wavefunct…
Approaching the Full Configuration Interaction Ground State from an Arbitrary Wavefunction with Gradient Descent and Quasi-Newton Algorithms
Carlos A. Jiménez-Hoyos
We consider gradient descent and quasi-Newton algorithms to optimize the full configuration interaction (FCI) ground state wavefunction starting from an arbitrary reference state $…
Minimal matrix product states and generalizations of mean-field and geminal wavefunctions
Henrik R. Larsson, Carlos A. Jiménez-Hoyos, Garnet Kin-Lic Chan
Simple wavefunctions of low computational cost but which can achieve qualitative accuracy across the whole potential energy surface (PES) are of relevance to many areas of electron…
On a dual representation of the Goldstone manifold
Carlos A. Jiménez-Hoyos, Rayner R. Rodríguez-Guzmán, Thomas M. Henderson +1
An intrinsic wavefunction with a broken continuous symmetry can be rotated with no energy penalty leading to an infinite set of degenerate states known as a Goldstone manifold. In…
