  2. 1. Pair production, vacuum birefringence and radiation reaction in strong field QED

    Author : Greger Torgrimsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; worldline instantons; lightfront quantisation; radiation reaction; vacuum birefringence; nonperturbative pair production;

    Abstract : In this thesis we consider three QED phenomena in strong electromagnetic fields: Schwinger pair production, vacuum birefringence and radiation reaction. We study electron-positron pair production in a variety of field configurations and, using complex worldline instantons, reveal new insights into the case of fields with lightlike inhomogeneities.

  4. 2. QED and collective effects in vacuum and plasmas

    Author : Joakim Lundin; Mattias Marklund; Thomas Heinzl; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QED; quantum electrodynamics; quantum plasmas; quantum vacuum; Plasma physics; Plasmafysik; fysik; Physics;

    Abstract : The theory of quantum electrodynamics (QED) was born out of an attempt to merge Einsteins theory of special relativity and quantum mechanics. Einsteins energy/mass equivalence together with Heisenberg's uncertainty principle allows for particle pairs to be spontaneously created and annihilated in vacuum. READ MORE
