The ponderomotive force due to the intrinsic spin in extended fluid and kinetic models
M. Stefan, J. Zamanian, G. Brodin +2
In this paper we calculate the contribution to the ponderomotive force in a plasma from the electron spin using a recently developed model. The spin-fluid model used in the present…
Generation of wakefields by whistlers in spin quantum magnetoplasmas
A. P. Misra, G. Brodin, M. Marklund +1
The excitation of electrostatic wakefields in a magnetized spin quantum plasma by the classical as well as the spin-induced ponderomotive force (CPF and SPF, respectively) due to w…
Strong field effects in laser pulses: the Wigner formalism
Florian Hebenstreit, Anton Ilderton, Mattias Marklund +1
We investigate strong field vacuum effects using a phase space approach based on the Wigner formalism. We calculate the Wigner function in a strong null-field background exactly, u…
Pair production in laser fields: finite size effects
Thomas Heinzl, Anton Ilderton, Mattias Marklund
We discuss pair creation in a strong laser background. Using lightfront field theory, we show that all the physics is contained in the lightfront momentum transfer from the laser,…
From extended phase space dynamics to fluid theory
Jens Zamanian, Martin Stefan, Mattias Marklund +1
We derive a fluid theory for spin-1/2 particles starting from an extended kinetic model based on a spin-projected density matrix formalism. The evolution equation for the spin dens…
Strong Field, Noncommutative QED
Anton Ilderton, Joakim Lundin, Mattias Marklund
We review the effects of strong background fields in noncommutative QED. Beginning with the noncommutative Maxwell and Dirac equations, we describe how combined noncommutative and…
Spin kinetic theory - quantum kinetic theory in extended phase space
M. Marklund, J. Zamanian, G. Brodin
The concept of phase space distribution functions and their evolution is used in the case of en enlarged phase space. In particular, we include the intrinsic spin of particles and…
Finite size effects in stimulated laser pair production
Thomas Heinzl, Anton Ilderton, Mattias Marklund
We consider stimulated pair production employing strong-field QED in a high-intensity laser background. In an infinite plane wave, we show that light-cone quasi-momentum can only b…
