PySCF Quantum Chemistry

Purpose

Provides expert guidance on PySCF quantum chemistry calculations, including post-Hartree-Fock methods and multireference approaches.

Capabilities

• Hartree-Fock and post-HF methods
• Coupled cluster (CCSD, CCSD(T))
• CASSCF/CASPT2 multireference
• Periodic boundary conditions
• Relativistic corrections
• DMRG integration

Usage Guidelines

1. System Setup: Define molecular geometry and basis set
2. Mean-Field: Run Hartree-Fock calculations
3. Correlation: Apply post-HF methods for correlation
4. Multireference: Use CASSCF for strongly correlated systems
5. Advanced: Include relativistic effects when needed

Tools/Libraries

• PySCF
• Block2
• libcint
