A comparison of delayed radiobiological effects of depleted-uranium munitions versus fourth-generation nuclear weapons
Andre Gsponer, Jean-Pierre Hurni, Bruno Vitale
It is shown that the radiological burden due to the battlefield use of circa 400 tons of depleted-uranium munitions in Iraq (and of about 40 tons in Yugoslavia) is comparable to th…
Explicit closed-form parametrization of SU(3) and SU(4) in terms of complex quaternions and elementary functions
Andre Gsponer
Remarkably simple closed-form expressions for the elements of the groups SU(n), SL(n,R), and SL(n,C) with n=2, 3, and 4 are obtained using linear functions of biquaternions instead…
Lanczos's equation as a way out of the spin 3/2 crisis?
Andre Gsponer, Jean-Pierre Hurni
It is shown (1) that Lanczos's quaternionic formulation of Dirac's equation does not lead to a solution of the problems that plague the standard spin 3/2 theory based on the Rarita…
Comment on formulating and generalizing Dirac's, Proca's, and Maxwell's equations with biquaternions or Clifford numbers
Andre Gsponer, Jean-Pierre Hurni
Many difficulties of interpretation met by contemporary researchers attempting to recast or generalize Dirac's, Proca's, or Maxwell's theories using biquaternions or Clifford numbe…
Non-linear field theory for lepton and quark masses
Andre Gsponer, Jean-Pierre Hurni
Barut's formula for the mass of leptons is successfully extended to quarks. A very simple non-linear scalar field model explains both the N^4 power law dependence of the mass, and…
The physical heritage of Sir W.R. Hamilton
Andre Gsponer, Jean-Pierre Hurni
150 years after the discovery of quaternions, Hamilton's conjecture that quaternions are a fundamental language for physics is reevaluated and shown to be essentially correct, prov…
On the "equivalence" of the Maxwell and Dirac equations
Andre Gsponer
It is shown that Maxwell's equation cannot be put into a spinor form that is equivalent to Dirac's equation. First of all, the spinor ψin the representation \vec{F} = ψ\vec{u} \bar…
