Constraining Gravitational Theories by Observing Magnetic White Dwarfs
Oliver Preuss, Stefan Jordan, Mark P. Haugan +1
Under the assumption of a specific nonminimal coupling of torsion to Under the assumption of a specific nonminimal coupling of torsion to electromagnetism, spacetime is birefringen…
An astronomical search for evidence of new physics: Limits on gravity-induced birefringence from the magnetic white dwarf RE J0317-853
Oliver Preuss, Mark P. Haugan, Sami K. Solanki +1
The coupling of the electromagnetic field directly with gravitational gauge fields leads to new physical effects that can be tested using astronomical data. Here we consider a part…
Solar constraints on new couplings between electromagnetism and gravity
S. K. Solanki, O. Preuss, M. P. Haugan +6
The unification of quantum field theory and general relativity is a fundamental goal of modern physics. In many cases, theoretical efforts to achieve this goal introduce auxiliary…
