Gravity-induced birefringence within the framework of Poincare gauge theory
Oliver Preuss, Sami K. Solanki, M. P. Haugan +1
Gauge theories of gravity provide an elegant and promising extension of general relativity. In this paper we show that the Poincaré gauge theory exhibits gravity-induced birefringe…
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…
Principles of Equivalence: Their Role in Gravitation Physics and Experiments that Test Them
Mark P. Haugan, C. Lämmerzahl
Modern formulations of equivalence principles provide the foundation for an efficient approach to understanding and organizing the structural features of gravitation field theories…
On the interpretation of Michelson-Morley experiments
Claus Lämmerzahl, Mark P. Haugan
Recent proposals for improved optical tests of Special Relativity have renewed interest in the interpretation of such tests. In this paper we discuss the interpretation of modern r…
