  1. 1. Relativistic light-matter interaction

    Författare :Tor Kjellsson Lindblom; Eva Lindroth; Bernard Piraux; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-dependent Dirac equation; Beyond dipole effects; Relativistic effects; High-Intensity laser-matter interaction; teoretisk fysik; Theoretical Physics;

    Sammanfattning : During the past decades, the development of laser technology has produced pulses with increasingly higher peak intensities. These can now be made such that their strength rivals, and even exceeds, the atomic potential at the typical distance of an electron from the nucleus. LÄS MER

  3. 2. Relativistic particle mechanics : a hamiltonian approach

    Författare :Andreas Bette; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This study is devoted to certain fundamental problems within theoretical physics. The aim is to show that there exists a consistent Poincare invariant Hamiltonian formalism describing interactions between any number of discrete particles forming an isolated (in general spinning) system. No fields or potentials are needed for the description. LÄS MER

  4. 3. Relativistic fireworks cosmology

    Författare :Lennart Widlund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fyrverkeri;

  5. 4. Relativistic light-matter interaction

    Författare :Tor Kjellsson; Eva Lindroth; Victor Kimberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Sammanfattning : In this licentiate thesis light-matter interaction between hydrogen and superintense attosecond pulses is studied. The specific aim here is to identify for what intensities the non-relativistic calculations, given by solving the time dependent Schrödinger equation, no longer are valid. LÄS MER
