New preprint from Widom-Larsen group

  • Electron Capture in a Fully Ionized Plasma -- http://arxiv.org/abs/1409.5344


    ABSTRACT:
    Properties of fully ionized water plasmas are discussed including plasma charge density oscillations and the screening of the Coulomb law especially in the dilute classical Debye regime. A kinetic model with two charged particle scattering events determines the transition rate per unit time for electron capture by a nucleus with the resulting nuclear transmutations. Two corrections to the recent Maiani et.al. calculations are made: (i) The Debye screening length is only employed within its proper domain of validity. (ii) The WKB approximation employed by Maiani in the long De Broglie wave length limit is evidently invalid. We replace this incorrect approximation with mathematically rigorous Calogero inequalities in order to discuss the scattering wave functions. Having made these corrections, we find a verification for our previous results based on condensed matter electro-weak quantum field theory for nuclear transmutations in chemical batteries.

    I don't understand well the debate, as it seems deep theoretical QM in material.
    Debye temperature have been cited by DGT ( :huh: ) as a triggering temperature...
    It seems to be a temperature at which in a crystal the phonons start to behave very differently...


    This paper seems to apply to Mizuno experiments? does it?


    need some subtitles.


    Note for those who don't know that Larsen have broke from Widom-Srivastava.


    my dream would be that Widom-Srivastava merge their theory with Storms, improve both, and solve the problem.

  • Just some clarification


    1. Debye screening length is a term used in plasma physics (Widom's paper)
    2. Debye temperature is used in solid state physics for some obscure mathematical historical reason to describe the maximum frequency of vibration occurring in a crystal lattice. Diamond has the highest max vibration frequency (Debye temperature) of all materials since it has the strongest bond and the low mass of carbon and hence highest possible atomic vibration frequency 2pi*f=sqrt(mass/force constant).


    S.Ó.

    thanks,


    wikipedia explains what Debye length mean... no relation to Debye temp indeed....

    In plasmas and electrolytes the Debye length (also called Debye radius), named after the Dutch physicist and physical chemistPeter Debye, is the measure of a charge carrier's net electrostatic effect in solution, and how far those electrostatic effects persist. A Debye sphere is a volume whose radius is the Debye length, in which there is a sphere of influence, and outside of which charges are electrically screened. The notion of Debye length plays an important role in plasma physics, electrolytes and colloids(DLVO theory).
