Lattice Dynamics Toolkit

Anharmonic lattice dynamics routines. Force constant format and many implementations are copied from the TDEP code. I do not gurantee feature parity to TDEP though.

Features:

  • Read IFCs
  • Remap IFCs to supercell
  • Calculate effective Hamiltonian energies
  • Generate canonical configurations
    • Calculate Hamiltonian energies and/or LAMMPS supported potential on the fly
  • Anharmonic free energy
  • Compute most harmonic properties (DOS, dispersion etc.)

In Progress:

  • Long range interactions
