  • Rare events, path sampling and the OpenPathSampling package

    Rare events, path sampling and the OpenPathSampling package

      In the last few years, modelling of rare events has made tremendous progress and several computational methods have been put forward to study these events. Despite this effort, new approaches have not yet been included, with adequate efficiency and scalability, in common simulation packages. One objective of the Classical …Read More »
  • LibOMM : Orbital Minimization Method Library

    Purpose The library LibOMM solves the Kohn-Sham equation as a generalized eigenvalue problem for a fixed Hamiltonian. It implements the orbital minimization method (OMM), which works within a density matrix formalism. The basic strategy of the OMM is to find the set of Wannier functions (WFs) describing the occupied subspace …Read More »
