  10. IMA 2013 UQ: DFT-based Thermal Properties: Three Levels of Error Management

    10 Feb 2014 | | Contributor(s):: Kurt Lejaeghere

    It is often computationally expensive to predict finite-temperature properties of a crystal from density-functional theory (DFT). The temperature-dependent thermal expansion coefficient α, for example, is calculated from the phonon spectrum, and the melting temperature Tm can only be obtained...

  15. Large-scale first principles configuration interaction calculations of optical absorption in boron clusters

    07 Mar 2012 | | Contributor(s):: Ravindra L Shinde

    We have performed systematic large-scale all-electron correlated calculations on boron clustersBn (n=2–5), to study their linear optical absorption spectra. Several possible isomers of each clus-ter were considered, and their geometries were optimized at the coupled-cluster singles doubles(CCSD)...
