Nonlinear three-wave interaction in pair plasmas.
It is shown that nonlinear three-wave interaction, described by vector-product-type nonlinearities, in pair plasmas implies much more restrictive conditions for a double energy transfer, as compared to electron-ion plasmas.
متن کاملDust ion-acoustic shocks in quantum dusty pair-ion plasmas
Abstract The formation of dust ion-acoustic shocks (DIASs) in a four-component quantum plasma whose constituents are electrons, both positive and negative ions and immobile charged dust grains, is studied. The effects of both the dissipation due to kinematic viscosity and the dispersion caused by the charge separation as well as the quantum tunneling due to the Bohm potential are taken into acc...
متن کاملGeneralized Relativistic Magnetohydrodynamic Equations for Pair and Electron-Ion Plasmas
We derived one-fluid equations based on a relativistic two-fluid approximation of e pair plasma and electron-ion plasma to reveal the specific relativistic nature of their behavior. Assuming simple condition on the relativistic one-fluid equations, we propose generalized relativistic magnetohydrodynamic (RMHD) equations which satisfy causality. We show the linear analyses of these equations reg...
متن کاملGlobal convective cell formation in pair-ion plasmas
The global electrostatic mode in pair-ion plasmas is discussed for cylindric geometry and for a radially inhomogeneous equilibrium density. In the case of a Gaussian radial density profile, exact analytical eigen solutions are found in terms of the Kummer confluent hypergeometric functions. The mode is identified as a convective cell propagating in the poloidal and axial direction, having at th...
متن کاملSpin and pair density wave glasses
Spontaneous breaking of translational symmetry—known as ‘density wave’ order—is common in nature. However such states are strongly sensitive to impurities or other forms of frozen disorder leading to fascinating glassy phenomena. We analyze impurity effects on a particularly ubiquitous form of broken translation symmetry in solids: a Spin Density Wave (SDW) with spatially modulated magnetic ord...
