Second-Derivative-Corrected FANPT for Robust Continuation of Nonlinear Wavefunction Equations
Rugwed Lokhande, Krisztina Zsigmond, Paul W. Ayers +1
We present a second-derivative-corrected extension of the Flexible Ansatz for N-body Perturbation Theory (FANPT) for solving nonlinear Flexible Ansatz for N-body Configuration Inte…
Fanpy 2.0: Wavefunction Implementation and Analysis Tools for Flexible Ansatz Design
Krisztina Zsigmond, Rugwed Lokhande, Carlos E. V. de Moura +6
Fanpy is a Python library for developing new wavefunction methods. It enables users to quickly convert mathematical expressions into working code through a modular design based on…
Towards more accurate natural orbital functional approximations: including 4-index cumulant contributions
Valerii Chuiko, Paul W. Ayers, Eduard Matito
Accurate modeling of bond breaking remains a central challenge for reduced density matrix functional theory (RDMFT). Although some modern functionals can yield reasonably accurate…
