PAOFLOW's capabilities:

• Construction of PAO Hamiltonians from the DFT wavefunctions onto pseudo atomic orbitals
• Hamiltonian data for further processing (ACBN0, PAOtransport, etc.)
• External fields and non scf ACBN0 correction
• Spin orbit correction of non SO calculations
• Bands along standard paths in the BZ
• Interpolation of Hamiltonians on arbitrary Monkhorst and Pack k-meshes
• Adaptive smearing for BZ and Fermi surface integration
• Density of states (and projected DOS)
• Fermi surfaces and spin textures
• Boltzmann transport (conductivity, Seebeck coefficient, electronic contribution to thermal conductivity
• dielectric function (absorption coefficients and EELS)
• Berry curvature and anomalous Hall conductivity (including magnetic circular dichroism spectra)
• spin Berry curvature and spin Hall conductivity (including spin circular dichroism spectra)
• Band topology (Z2 invariants, Berry and spin Berry curvature along standard paths in BZ, critical points

Example code for PAOFLOW is available on GitHub: https://github.com/marcobn/PAOFLOW/examples/
