PM allows one to compute various electronic and phononic properties of crystals.

There are currently three major versions of the code.

  1. The “old” code: http://grandcentral.apam.columbia.edu:5555/principia_materia_doc_v0/

  2. The “new” code: http://grandcentral.apam.columbia.edu:5555/pmdocs/

  3. The “development” code, which is documented here.
