  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

  3. 2. SEMICLASSICAL TUNNELING EFFECT

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Johan Öhman; [2014]
    Nyckelord :tunneling effect; cold fusion;

    Sammanfattning : This work is a contribution to the theory of the quantum tunneling effect. In the literature at least two barriers are studied, for which the third-order contribution to the phase - integral asymptotic approximation of the transmission coefficient do not contribute. These are the parabolic barrier and the inverse Morse barrier. LÄS MER

  4. 3. Supersymmetry in Quantum Mechanics

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Simon Kuberski; [2014]
    Nyckelord :supersymmetric quantum mechanics; partner potentials; quantum mechanics; partner Hamiltonian; shape invariant potential; shape invariance; Morse potential; Physics and Astronomy;

    Sammanfattning : This thesis gives an introduction to the basic formalism of one-dimensional supersymmetric quantum mechanics. The factorization of a Hamiltonian is used to create a supersymmetric partner Hamiltonian. LÄS MER

  5. 4. FE analysis and design of the mechanical connection in an osseointegrated prosthesis system

    Master-uppsats, Mekanik

    Författare :Emelie Magnusson; [2011]
    Nyckelord :abutment; finite element analysis; gait analysis; implant; Integrum; Morse taper; osseointegration; prosthesis; titanium;

    Sammanfattning : In this master thesis the connection between the two major parts of an osseointegrated prosthesis system for lower limb amputees has been investigated by finite element (FE) analysis. The prosthesis system is developed by Integrum and the current design consists of a fixture, which is integrated in the residual bone, an abutment that penetrates the skin and an abutment screw that holds the parts together.
