  1. 1. Relativistic light-matter interaction

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Tor Kjellsson Lindblom; Stockholms universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-dependent Dirac equation; Beyond dipole effects; Relativistic effects; High-Intensity laser-matter interaction; Theoretical Physics; teoretisk fysik;

    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

  2. 2. Relativistic fireworks cosmology

    Detta är en avhandling från Stockholm : Stockholm University

  3. 3. Relativistic light-matter interaction

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Tor Kjellsson; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    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

  5. 5. Relativistic theory of laser-induced magnetization dynamics

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ritwik Mondal; Uppsala universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Relativistic quantum electrodynamics; magneto-optics; spin-orbit coupling; ultrafast demagnetization; inverse Faraday effect; magnetic inertia; Gilbert damping; Fysik; Physics;

    Sammanfattning : Ultrafast dynamical processes in magnetic systems have become the subject of intense research during the last two decades, initiated by the pioneering discovery of femtosecond laser-induced demagnetization in nickel. In this thesis, we develop theory for fast and ultrafast magnetization dynamics. LÄS MER
