Dynamics of spin 1/2 quantum plasmas
M. Marklund, G. Brodin
The fully nonlinear governing equations for spin 1/2 quantum plasmas are presented. Starting from the Pauli equation, the relevant plasma equations are derived, and it is shown tha…
Spin magnetohydrodynamics
G. Brodin, M. Marklund
Starting from the non-relativistic Pauli description of spin-1/2 particles, a set of fluid equations, governing the dynamics of such particles interacting with external fields and…
Modulational Instability of Nonlinearly Interacting Incoherent Sea States
P. K. Shukla, M. Marklund, L. Stenflo
The modulational instability of nonlinearly interacting spatially incoherent Stokes waves is analyzed. Starting from a pair of nonlinear Schroedinger equations, we derive a coupled…
Modulational instability of spatially broadband nonlinear optical pulses in four-state atomic systems
M. Marklund, P. K. Shukla, R. Bingham +1
The modulational instability of broadband optical pulses in a four-state atomic system is investigated. In particular, starting from a recently derived generalized nonlinear Schröd…
Nonlinear wave interactions in quantum magnetoplasmas
P. K. Shukla, S. Ali, L. Stenflo +1
Nonlinear interactions involving electrostatic upper-hybrid (UH), ion-cyclotron (IC), lower-hybrid (LH), and Alfven waves in quantum magnetoplasmas are considered. For this purpose…
Graviton mediated photon-photon scattering in general relativity
G. Brodin, D. Eriksson, M. Marklund
In this paper we consider photon-photon scattering due to self-induced gravitational perturbations on a Minkowski background. We focus on four-wave interaction between plane waves…
