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

   Författare :Ritwik Mondal; Peter M. Oppeneer; Jan Rusz; Olle Eriksson; Paul-Antoine Hervieux; Uppsala universitet; []
   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

3. 2. Electron transfer and fragmentation in fullerene collisions

   Författare :Henning Zettergren; Henrik Cederquist; Paul-Antoine Hervieux; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fullerene; Physics; Fysik;

   Sammanfattning : In this thesis, we present results from detailed gas phase studies of intrinsic properties of fullerenes (C60) and clusters of fullerenes as probed by slow multiply charged (atomic or cluster) ions in combination with coincidence time-of-flight mass spectrometry. We have investigated the structures, stabilities, and the electron mobilities of multiply charged clusters of fullerenes, (C60)nr+ (r=2-5). LÄS MER
