Single particle multipole expansions from Micromagnetic Tomography
David Cortés-Ortuño, Karl Fabian, Lennart V. de Groot
Micromagnetic tomography aims at reconstructing large numbers of individual magnetizations of magnetic particles from combining high-resolution magnetic scanning techniques with mi…
A uniqueness theorem in potential theory with implications for tomography-assisted inversion
Karl Fabian, Lennart V. de Groot
Inversion of potential field data is a central technique of remote sensing in physics, geophysics, neuroscience and medical imaging. In spite of intense research, uniqueness theore…
Energy barriers in three-dimensional micromagnetic models and the physics of thermo-viscous magnetization in multidomain particles
Karl Fabian, Valera P. Shcherbakov
A first principle micromagnetic and statistical calculation of viscous remanent magnetization (VRM) in an ensemble of cubic magnetite pseudo single-domain particles is presented. T…
Do Galaxies Change in Size ? An Angular Size Test at Low Redshift with SDSS Data
Alexander Unzicker, Karl Fabian
Based on magnitudes and Petrosian radii from the Sloan Digital Sky Survey (SDSS, data release 7) at low redhift (z <0.2), we developed a test of galaxy-size evolution. For this fir…
A Solar System Test of Mach's Principle with Gravimetric Data
Alexander Unzicker, Karl Fabian
We present a new test for a possible Mach-Sciama dependence of the Gravitational constant G. According to Ernst Mach (1838-1916), the gravitational interaction depends on the distr…
Displacement Field and Elastic Energy of a Circular Twist Disclination for Large Deformations - an Example how to Treat Nonlinear Boundary Value Problems with Computer Algebra Systems
Alexander Unzicker, Karl Fabian
A circular twist disclination is a nontrivial example of a defect in an elastic continuum that causes large deformations. The minimal potential energy and the corresponding displac…
