Entropic Force in MHD, MHD turbulence, and the Entropy-Kinetic Equation

W. Baumjohann, R. A. Treumann

Following earlier work, reference is made to the classical entropic force which results from spatially variable disorder, an exclusively repulsive force. In terms of macroscopic va…

ECMI Resonance in AKR Revisited: Hyperbolic Resonance, Harmonics, Wave-Wave Interaction

W. Baumjohann, R. A. Treumann

Recapitulation of the resonance condition for the fundamental and higher electron cyclotron harmonics in the Electron Cyclotron Maser Instability (ECMI) enables radiation below and…

Auroral Kilometric Radiation -- the Electron Cyclotron Maser Paradigm

W. Baumjohann, R. A. Treumann

Auroral kilometric radiation (AKR) is the paradigm of intense radio emission from planetary magnetospheres. Being close to the electron gyro frequency and/or its lower harmonics, i…

Diffuse Josephson Radiation in Turbulence

R. A. Treumann, Wolfgang Baumjohann

The possibility of generating diffuse radiation in extended astronomical media by plasma turbulence is investigated under the assumption that the turbulence can be understood as an…

Condensate formation in collisionless plasma

R. A. Treumann, Wolfgang Baumjohann

Particle condensates in general magnetic mirror geometries in high temperature plasma may be caused by a discrete resonance with thermal ion-acoustic background noise near mirror p…

Olbert's kappa Fermi and Bose distributions

R. A. Treumann, Wolfgang Baumjohann

The quantum version of Olbert's kappa distribution applicable to fermions is obtained. Its construction is straightforward but requires recognition of the differences in the nature…
