Stability of two-dimensional ion-acoustic wave packets in quantum plasmas
Amar P. Misra, Mattias Marklund, Gert Brodin +1
The nonlinear propagation of two-dimensional (2D) quantum ion-acoustic waves (QIAWs) is studied in a quantum electron-ion plasma. By using a 2D quantum hydrodynamic model and the m…
Rogue waves in the atmosphere
L. Stenflo, M. Marklund
The appearance of rogue waves is well known in oceanographics, optics, and cold matter systems. Here we show a possibility for the existence of atmospheric rogue waves.
Spin induced nonlinearities in the electron MHD regime
Martin Stefan, Gert Brodin, Mattias Marklund
We consider the influence of the electron spin on the nonlinear propagation of whistler waves. For this purpose a recently developed electron two-fluid model, where the spin up- an…
Laser intensity effects in noncommutative QED
Thomas Heinzl, Anton Ilderton, Mattias Marklund
We discuss a two-fold extension of QED assuming the presence of strong external fields provided by an ultra-intense laser and noncommutativity of spacetime. While noncommutative ef…
Noncommutativity and the lightfront
Thomas Heinzl, Anton Ilderton, Mattias Marklund
We discuss various limits which transform configuration space into phase space, with emphasis on those related to lightfront field theory, and show that they are unified by spectra…
Growth rate and the cutoff wavelength of the Darrieus-Landau instability in laser ablation
Mikhail Modestov, Vitaly Bychkov, Damir Valiev +1
The main characteristics of the linear Darrieus-Landau instability in the laser ablation flow are investigated. The dispersion relation of the instability is found numerically as a…
