  1. 1. Decay of solutions to the Klein-Gordon equation on some expanding cosmological spacetimes

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Amol Sasane; [2019]
    Nyckelord :Klein-Gordon equation; general relativity; FLRW models; Schwarzschild-de Sitter; Reissner-Nordström-de Sitter; Physics and Astronomy;

    Sammanfattning : The decay of solutions to the Klein-Gordon equation is studied in two expanding cosmological spacetimes, namely (1) the de Sitter universe in flat Friedmann-Lemaitre-Robertson-Walker (FLRW) form, and (2) the cosmological region of the Reissner-Nordström-de Sitter (RNdS) model. Using energy methods, for initial data with finite higher order energies, bounds on the decay rates of the solution are obtained. LÄS MER

  3. 2. The Klein-Gordon Equation and Pionic Atoms

    Kandidat-uppsats, KTH/Teoretisk fysik

    Författare :Anna Nolinder; Elin Sandberg; [2014]
    Nyckelord :;

    Sammanfattning : This bachelor thesis introduces the Klein-Gordon equation and pionic atoms through a historical review. It discusses properties of the equation and its continuity equation based on a comparison with the Schrödinger equation and its continuity equation. LÄS MER

  4. 3. Retardation effects in fundamental physics

    Kandidat-uppsats, Teoretisk fysik

    Författare :Fredrik Härlin; [2011]
    Nyckelord :shift; dirac equation; klein gordon equation; retardation; fundamental physics; retardation; dirac ekvationen; klein gordon ekvationen; fundamental fysik;

    Sammanfattning : Speculations in the signicance of retardation aects in fundamental physics, especiallythe Dirac equation, that Atiyah and Moore bring up in "A shifted view of fundamental physics" are summarized and reviewedin terms of basic undergraduate conceptions. Some remarks are further investigated and ashifted version of the Klein Gordon equation is derived. LÄS MER
