1. 1. Pair Production and the Light-Front Vacuum

   Master-uppsats, Institutionen för fysik

   Författare :Ramin Ghorbani Ghomeshi; [2013]
   Nyckelord :Strong-Field QED; Quantum Vacuum; Schwinger Pair Production Mechanism; Dirac Forms of Relativistic Dynamics; Light-front Quantization; Zero-mode Issue; DLCQ; Worldline Approach;

   Sammanfattning : Dominated by Heisenberg's uncertainty principle, vacuum is not quantum mechanically an empty void, i.e. virtual pairs of particles appear and disappear persistently. This nonlinearity subsequently provokes a number of phenomena which can only be practically observed by going to a high-intensity regime. LÄS MER

3. 2. Pair Annihilation in a Laser Pulse

   Master-uppsats, Institutionen för fysik

   Författare :Petter Johansson; [2011]
   Nyckelord :Pair Annihilation; Laser Pulses; XFEL; ELI; Strong Field QED; Intense Field QED;

   Sammanfattning : The thesis analyses the process of pair annihilation into one photon in a laser pulse. The theory of how to include pulse shapes in Strong Field QED and the resulting cross section is presented. The cross section is calculated and estimated for lasers of ELI and XFEL facilites. LÄS MER
