The Cosmology of a Universe with Spontaneously-Broken Lorentz Symmetry
P. G. Ferreira, B. M. Gripaios, R. Saffari +1
A self consistent effective field theory of modified gravity has recently been proposed with spontaneous breaking of local Lorentz invariance. The symmetry is broken by a vector fi…
Modifying gravity with the Aether: an alternative to Dark Matter
T. G Zlosnik, P. G Ferreira, G. D Starkman
There is evidence that Newton and Einstein's theories of gravity cannot explain the dynamics of a universe made up solely of baryons and radiation. To be able to understand the pro…
The Vector-Tensor nature of Bekenstein's relativistic theory of Modified Gravity
T. G. Zlosnik, P. G. Ferreira, Glenn D. Starkman
Bekenstein's theory of relativistic gravity is conventionally written as a bi-metric theory. The two metrics are related by a disformal transformation defined by a dynamical vector…
