VMD is a molecular visualization program for displaying, animating, and analyzing large biomolecular systems using 3-D graphics and built-in scripting. Research on the Fenna-Matthews-Olsen complex in Green Sulfur Bacteria serves as a suitable model for the atomistic investigation about the first steps of energy transfer during Photosynthesis. 03 SP9&SP10 Linux Synopsys. L Mobility of the Fermi Hole in a Single-Determinant Wavefunction. This would require you to familiarize yourself with at least one software that incorporates DFT in the material model such as VASP Code, SIESTA Code, or Quantum Espresso Code. VASP Manual for INCAR tags. Clearly, in VMC the trial wavefunction completely determines the accuracy and statistical efficiency of the result. After we've completed a few simulations, it can be very useful to visualize the electronic structure of our system. The energy cut-off values were 400 eV (wave function) and 2400 eV (augmented charge). XcrySDen - XcrySDen Dankook Univ. The interactions between the electrons and ions are described using norm-conserving or ultrasoft pseudopotentials, or the projector-augmented-wave method. This page lists links to the web sites which have information about software and software developers (academic centers, national labs, industrial companies and individuals). Unsurpassed visualization and modern computational models accessed from the most user-friendly interface in the business. ABINIT ABINIT is a package whose main program allows one to find the total energy, charge density, and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within density functional theory (DFT), using pseudopotentials and a plane-wave basis. 0-2006 flomerics flovent Socet Set v5. A method for computing expectation values in the ground state of a given quantum many-body system in discrete space.
