Developing classical potentials for heavy elements

There are significant obstacles to multi-scale computational approaches in nuclear science. Notable is the absence of classical potentials that describe the atomic interactions of f-elements, and are required in order to perform classical simulations at the mesoscale. Within this theme the entire potential energy surface must be studied, including high-energy regimes. This requires knowledge of the electronic response of f-elements and mapping it to a classical description, imparting new physics to currently existing paradigms.

In the Clark group we are developing interatomic potentials for f-elements using the force matching algorithm, which utilizes an extensive knowledge of the wave function and wave function response.

These potentials are being generated so that we can study study f-element separation, in addition to f-element bearing materials under extreme environments in the near future.

To help us fit these potentials we have initiated the WSU - Computational Actinide Science Database (CANS - www.cans.wsu.edu) where computational chemists and materials scientists can upload thier simulation data to be added to the fitting database. This website also provides a forum for the discussion of condensed and gas phase actinide chemistry.
