Energy conditions in consistent perfect fluid cosmology
Davide Batic, Christian G. Boehmer, Denys Dutykh
Motivated by recent work on consistent fluid couplings in gravity, we study cosmology in the nontrivial model using the Brown variational principle f…
Cosmological fluids with boundary term couplings
Christian G. Boehmer, Antonio d'Alfonso del Sordo
Cosmological models can be studied effectively using dynamical systems techniques. Starting from Brown's formulation of the variational principle for relativistic fluids, we introd…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Cosmological dynamical systems in modified gravity
Christian G. Boehmer, Erik Jensko, Ruth Lazkoz
The field equations of modified gravity theories, when considering a homogeneous and isotropic cosmological model, always become autonomous differential equations. This relies on t…
On Freud's superpotential in General Relativity and in Einstein-Cartan theory
Christian G. Boehmer, Friedrich W. Hehl
The identification of a suitable gravitational energy in theories of gravity has a long history, and it is well known that a unique answer cannot be given. In the first part of thi…
Does space-time torsion determine the minimum mass of gravitating particles?
Christian G. Boehmer, Piyabut Burikham, Tiberiu Harko +1
We derive upper and lower limits for the mass-radius ratio of spin-fluid spheres in Einstein-Cartan theory, with matter satisfying a linear barotropic equation of state, and in the…
