Nonlocal effects in high energy charged particle beams
Pontus Johannisson, Dan Anderson, Mietek Lisak +3
Within the framework of the thermal wave model, an investigation is made of the longitudinal dynamics of high energy charged particle beams. The model includes the self-consistent…
Nonlinear Propagation of Incoherent Photons in a Radiation Background
Padma K. Shukla, Mattias Marklund, Gert Brodin +1
The nonlinear propagation of intense incoherent photons in a photon gas is considered. The photon-photon interactions are governed by a pair of equations comprising a wave-kinetic…
Modulational and filamentational instabilities of two electromagnetic pulses in a radiation background
M. Marklund, P. K. Shukla, G. Brodin +1
The nonlinear interaction, due to quantum electrodynamical (QED) effects, between two electromagnetic pulses and a radiation gas is investigated. It is found that the governing equ…
Dynamics of radiation due to vacuum nonlinearities
Mattias Marklund, Gert Brodin, Lennart Stenflo +1
In quantum electrodynamics, photon-photon scattering can be the result of the exchange of virtual electron-positron pairs. This gives rise to a non-trivial dispersion relation for…
