Dark spinors with torsion in cosmology
Christian G. Boehmer, James Burnett
We solve one of the open problems in Einstein-Cartan theory, namely we find a natural matter source whose spin angular momentum tensor is compatible with the cosmological principle…
Stability of the Schwarzschild Interior in Loop Quantum Gravity
Christian G. Boehmer, Kevin Vandersloot
In recent work, the Schwarzschild interior of a black hole was investigated, incorporating quantum gravitational modifications due to loop quantum gravity. The central Schwarzschil…
Solar system tests of brane world models
Christian G. Boehmer, Tiberiu Harko, Francisco S. N. Lobo
The classical tests of general relativity (perihelion precession, deflection of light, and the radar echo delay) are considered for the Dadhich, Maartens, Papadopoulos and Rezania…
Dynamics of dark energy with a coupling to dark matter
Christian G. Boehmer, Gabriela Caldera-Cabral, Ruth Lazkoz +1
Dark energy and dark matter are the dominant sources in the evolution of the late universe. They are currently only indirectly detected via their gravitational effects, and there c…
Wormhole geometries with conformal motions
Christian G. Boehmer, Tiberiu Harko, Francisco S. N. Lobo
Exact solutions of traversable wormholes were recently found under the assumption of spherical symmetry and the existence of a non-static conformal symmetry. In this paper, we veri…
Perfect fluid spheres with cosmological constant
Christian G. Boehmer, Gyula Fodor
We examine static perfect fluid spheres in the presence of a cosmological constant. New exact matter solutions are discussed which require the Nariai metric in the vacuum region. W…
