EOPDev 1.0.0

Develop effective one-electron potential (EOP) operators for Quantum Chemistry of extended molecular aggregates. The EOP technique enables to effectively eliminate electron repulsion integrals (ERI) from fragment-based (FB) methods, making them computationally more efficient while maintaining accuracy. By combination of EOP and FB methodologies, effective fragment parameters (EFP) can be defined.

Features

• Simple platform to develop custom EOPs
• Demonstrative examples of using EOPs
• Extensive Python interface
• Object-Oriented
