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

    University essay from KTH/Matematik (Avd.)

    Author : Albin Persson; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Institutionen för informationsteknologi

    Author : Tobias Skoglund; [2012]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

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

    Abstract : 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. READ MORE
