Calculating electronic correlations in the CASTEP ab initio code — •Vincent Sacksteder¹ and Evgeny Plekhanov² — ¹W155 Wilson Building, Royal Holloway University of London, Egham Hill, Egham, TW20 0EX, — ²Kings College London

We present new DMFT and GW features in the CASTEP DFT code. These features are designed to provide more accurate treatment of correlations between localized orbitals, of electronic screening, and of excited states. In present benchmarks on Cerium Oxide, the gamma phase of Cerium, and Silicon. We discuss the calculation of atomic forces within the GW framework.
