    Notes: [Auszug] Whereas the first of these is in order, the second simply does not exist at present. In an answer to criticism by Alfven, Babcock2 declares his belief that the effect of magneto-turbulence is small, but does not give any evidence for this point of view. There are several possible mechanisms which ...

    Velocity limitation of a neutral dust cloud colliding with a magnetized plasma (1988)
    Springer
    Astrophysics and space science 144 (1988), S. 31-42 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The problem is considered of a cloud of neutral dust moving into a cloud of static plasma which is confined in a magnetic field. Earlier experiments with rotating plasma devices and plasma guns on critical velocity limitation suggest that such limitation could also arise in the case of plasma-neutral dust interaction in cosmos. Nevertheless further analysis is required to provide a clear picture of the relations between the cosmical and laboratory conditions for plasma-neutral gas and plasma-neutral dust interaction. In particular this applies to the question how to relate the experiments, which are largely in the plasma-physical MHD range, to the cosmical interaction which appears to be mainly governed by kinetic effects.

    Beta limitation of matter-antimatter boundary layers (1988)
    Springer
    Astrophysics and space science 140 (1988), S. 77-83 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A model has earlier been proposed for a boundary layer which separates a cloud of matter from one of antimatter in a magnetized ambiplasma. In this model steady pressure equilibrium ceases to exist when a certain beta limit is exceeded. The latter is defined as the ratio between the ambiplasma and magnetic field pressures which balance each other in the boundary layer. Thus, at an increasing density, the high-energy particles created by annihilation within the layer are ‘pumped up’ to a pressure which cannot be balanced by a given magnetic field. The boundary layer then ‘disrupts’. The critical beta limit thus obtained falls within the observed parameter ranges of galaxies and other large cosmical objects. Provided that the considered matter-antimatter balance holds true, this limit is thus expected to impose certain existence conditions on matter-antimatter boundary layers. Such a limitation may apply to certain cosmical objects and cosmological models. The maximum time-scale for the corresponding disruption development has been estimated to be in a range from about 10−4 to 102s for boundary layers at ambiplasma particle densities in the range from 104 to 10−2 m−3, respectively.

    Problems of matter-antimatter boundary layers (1977)
    Springer
    Astrophysics and space science 46 (1977), S. 61-71 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract This paper outlines the problems of the quasi-steady matter-antimatter boundary layers discussed in Klein-Alfvén's cosmological theory, and a crude model of the corresponding ambiplasma balance is presented: (i) At interstellar particle densities, no well-defined boundary layer can exist in presence of neutral gas, nor can such a layer be sustained in an unmagnetized fully ionized ambiplasma. (ii) Within the limits of applicability of the present model, sharply defined boundary layers are under certain conditions found to exist in a magnetized ambiplasma. Thus, at beta values less than unity, a steep pressure drop of the low-energy components of matter and antimatter can be balanced by a magnetic field and the electric currents in the ambiplasma. (iii) The boundary layer thickness is of the order of 2x 0≃10/BT 0 1/4 metres, whereB is the magnetic field strength in MKS units andT 0 the characteristic temperature of the low-energy components in the layer.

    DERIVATION OF THE LEHNERT FIELD EQUATIONS FROM GAUGE THEORY IN VACUUM: SPACE CHARGE AND CURRENT (2000)
    Springer
    Foundations of physics 13 (2000), S. 179-184 
    Details
    ISSN: 1572-9524
    Keywords: Lehnert vacuum charge currents ; gauge theory
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract It is shown that the Lehnert field equations in vacuum, with concomitant space charge and current, can be derived straightforwardly from standard gauge theory applied in vacuum, using the concept of covariant derivative and Feynman's universal influence. The Lehnert and Proca field equations are shown to be inter-related through the well-known de Broglie theorem, in which the photon mass can be interpreted as finite. These ideas go some way towards addressing the inconsistency inherent in Maxwell's famous displacement current, which has no concomitant vacuum space charge.
