Gravity Probe C(lock) - Probing the gravitomagnetic field of the Earth by means of a clock experiment
Frank Gronwald, Eleonora Gruber, Herbert Lichtenegger +1
We outline a mission with the aim of directly detecting the gravitomagnetic field of the Earth. This mission is called Gravity Probe C. Gravity Probe C(lock) is based on a recently…
Maxwell's theory on a post-Riemannian spacetime and the equivalence principle
Roland A. Puntigam, Claus Lämmerzahl, Friedrich W. Hehl
The form of Maxwell's theory is well known in the framework of general relativity, a fact that is related to the applicability of the principle of equivalence to electromagnetic ph…
Volterra Distortions, Spinning Strings, and Cosmic Defects
Roland A. Puntigam, Harald H. Soleng
Cosmic strings, as topological spacetime defects, show striking resemblance to defects in solid continua: distortions, which can be classified into disclinations and dislocations,…
A quadratic curvature Lagrangian of Pawłowski and Rcaczka: a finger exercise with MathTensor
Efstratios Tsantilis, Roland A. Puntigam, Friedrich W. Hehl
Recently Pawłowski and Rcaczka proposed a unified model for the fundamental interactions which does not contain a physical Higgs field. The gravitational field equation of their mo…
The Use of Computer Algebra in Maxwell's Theory
R. A. Puntigam, E. Schrüfer, F. W. Hehl
We present a small computer algebra program for use in Maxwell's theory. The Maxwell equations and the energy-momentum current of the electromagnetic field are formulated in the la…
