 "description" "Static VASP pseudpotential GGA-PBE DFT calculation of the potential energy and atomic forces acting on a random cluster of 6 silicon atoms (this should correspond to the unrelaxed configuration used in KIM Tests ClusterEnergyAndForces_6atom_Si__TE_070700102518_000 and ClusterEnergyAndForces_6atom_Si__TE_070700102518_001).  A plane-wave basis with an energy cutoff of 250 eV was used.  A 1 x 1 x 1 gamma-centered Monkhorst-Pack k-point mesh was used (generating a total of 1 irredundant k-point)."

We will discuss: (a) partial occupancies within the framework of the linear tetrahedron method and the finite temperature density-functional theory, (b) iterative methods for the diagonalization of the Kohn-Sham Hamiltonian and a discussion of an efficient iterative method based on the ideas of Pulay's residual minimization, which is close to an order Natoms2 scaling even for relatively large systems, (c) efficient Broyden-like and Pulay-like mixing methods for the charge density including a new special ‘preconditioning’ optimized for a plane-wave basis set, (d) conjugate gradient methods for minimizing the electronic free energy with respect to all degrees of freedom simultaneously. We have implemented these algorithms within a powerful package called VAMP (Vienna ab-initio molecular-dynamics package). The program and the techniques have been used successfully for a large number of different systems (liquid and amorphous semiconductors, liquid simple and transition metals, metallic and semi-conducting surfaces, phonons in simple metals, transition metals and semiconductors) and turned out to be very reliable."

We show that by combining an improved description of the pseudowavefunction inside the cut-off radius with the concept of ultrasoft pseudopotentials introduced by Vanderbilt optimal compromise between transferability and plane-wave convergence can be achieved. With the new pseudopotentials, basis sets with no more than 75-100 plane waves per atom are sufficient to reproduce the results obtained with the most accurate norm-conserving pseudopotentials."
