A polarizable CASSCF/MM approach using the interface between OpenMMPol library and CFour
Tommaso Nottoli, Mattia Bondanza, Filippo Lipparini +1
We present a polarizable embedding quantum mechanics/molecular mechanics (QM/MM) framework for ground- and excited-state Complete Active Space Self-Consistent Field (CASSCF) calcul…
Reference CC3 Excitation Energies for Organic Chromophores: Benchmarking TD-DFT, BSE/ and Wave Function Methods
Iryna Knysh, Filippo Lipparini, Aymeric Blondel +4
To expand the QUEST database of highly-accurate vertical transition energies, we consider a series of large organic chromogens ubiquitous in dye chemistry, such as anthraquinone, a…
Cholesky decomposition in spin-free Dirac-Coulomb coupled-cluster calculations
Tereza Uhlířová, Davide Cianchino, Tommaso Nottoli +2
We present an implementation for the use of Cholesky decomposition (CD) of two-electron integrals within the spin-free Dirac-Coulomb (SFDC) scheme that enables to perform high-accu…
Geometric Optimization of Restricted-Open and Complete Active Space Self-Consistent Field Wavefunctions
Laurent Vidal, Tommaso Nottoli, Filippo Lipparini +1
We explore Riemannian optimization methods for Restricted-Open-shell Hartree-Fock (ROHF) and Complete Active Space Self-Consistent Field (CASSCF) methods. After showing that ROHF a…
MBE-CASSCF Approach for the Accurate Treatment of Large Active Spaces
Jonas Greiner, Ivan Gianni, Tommaso Nottoli +3
We present a novel implementation of the complete active space self-consistent field (CASSCF) method that makes use of the many-body expanded full configuration interaction (MBE-FC…
The OpenMMPol Library for Polarizable QM/MM Calculations of Properties and Dynamics
Mattia Bondanza, Tommaso Nottoli, Michele Nottoli +3
We present a new library designed to provide a simple and straightforward way to implement QM/AMOEBA and other polarizable QM/MM methods based on induced point dipoles. The library…
