  1. 1. Cost Efficient Interpolation of Potential Energy Surfaces for Quantum Dynamics

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Albin Persson; [2021]
    Nyckelord :;

    Sammanfattning : In calculating potential energy surfaces (PES) in quantum chemistry interpolation methods are sometimes used to get a sufficiently approximated surface. Kowalewski, Larsson and Heryudono (J Chem Phys, 148(8):084104) has developed an adaptive interpolation method to approximate a PES by polyharmonic splines interpolation. LÄS MER

  2. 2. Sponsorship : Is it a double-edged sword?

    Kandidat-uppsats, Ekonomihögskolan, ELNU

    Författare :Simon Liljehammar; Kristoffer Nilsson Kampitsch; [2012]
    Nyckelord :sport sponsorship; social identity; in-group; out-group; identification and commitment to a sport team;

    Sammanfattning : Today, sponsorship is an integrated communication tool used for the achievement of commercial objectives. As the marketing environment changes sport sponsorship has evolved into one of the fastest growing marketing sectors. LÄS MER

  3. 3. Efficient Wave Propagation in Discontinuous Media and Complex Geometry for Many-core Architectures

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för informationsteknologi

    Författare :Tobias Skoglund; [2012]
    Nyckelord :;

    Sammanfattning : We present an accelerated numerical solver for the scalar wave equation using one and two GPUs. We consider complex geometry and study accuracy when performing the computation in both single and double precision. The method uses a high-order accurate approximation of the derivatives using summation-by-parts operators. LÄS MER

  4. 4. On the Properties of a Few Electron-Hole system in a Double One-dimensional Harmonic Trap

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Fan Pan; [2012]
    Nyckelord :Electron-Hole system; Few-body; CI methods; Exciton-like; Double one-dimension; harmonic trap; Physics and Astronomy;

    Sammanfattning : One of the most important concepts in condensed matter physics is that of ``quasi particles''. The exciton is one such quasi particle. In semi-conductors, excitons are formed by the excitation of electrons from valence band to conduction band, which creates holes in the valence band. LÄS MER
