QE-GIPAW

This is the official Git repository of the GIPAW code for Quantum-Espresso.

Features

  • NMR shielding tensors, EFG tensors
  • EPR g-tensor, hyperfine couplings
  • Mössbauer
  • Norm-conserving (g-tensor only), USPP and PAW
  • LDA and GGA functionals
  • isolated and periodic systems
  • integration with Quantum-Environment (solvent effects)
