Capabilities

What the software page should communicate

Excited-State Theory

  • MRSF-TDDFT for ground and excited states
  • Analytic gradients and nonadiabatic couplings
  • Spin-orbit coupling roadmap
  • EKT-MRSF ionization and electron affinity work

Production Engine

  • HF and DFT ground-state workflows
  • Geometry optimization, transition states, and conical intersections
  • LibXC, DFT-D4, Molden, OpenMP, MPI, and BLAS/LAPACK integration
  • Python-driven testing, examples, and reproducible references

Performance Track

  • Integral routing and spherical-basis modernization
  • Davidson and response-kernel performance
  • GPU-oriented exchange-correlation and J/K exploration
  • Benchmark-backed release validation

Citation

Make citation and adoption easy

The new site should make the core OpenQP citation, method citations, installation routes, examples, and validation notes visible from one place.
