Microscopic and Macroscopic Behaviors of Palatini Modified Gravity Theories
Baojiu Li, David F. Mota, Douglas J. Shaw
We show that, within modified gravity, the non-linear nature of the field equations implies that the usual naive averaging procedure (replacing the microscopic energy-momentum by i…
Testing Alternative Theories of Dark Matter with the CMB
Baojiu Li, John D. Barrow, David F. Mota +1
We propose a method to study and constrain modified gravity theories for dark matter using CMB temperature anisotropies and polarization. We assume that the theories considered her…
Detecting a Lorentz-Violating Field in Cosmology
Baojiu Li, David F. Mota, John D. Barrow
We consider cosmology in the Einstein-aether theory (the generally covariant theory of gravitation coupled to a dynamical timelike Lorentz-violating vector field) with a linear aet…
The Cosmology of Ricci-Tensor-Squared Gravity in the Palatini Variational Approach
Baojiu Li, John D. Barrow, David F. Mota
We consider the cosmology of the Ricci-tensor-squared gravity in the Palatini variational approach. The gravitational action of standard general relativity is modified by adding a…
The Cosmology of Modified Gauss-Bonnet Gravity
Baojiu Li, John D. Barrow, David F. Mota
We consider the cosmology where some function f(G) of the Gauss-Bonnet term G is added to the gravitational action to account for the late-time accelerating expansion of the univer…
The Cosmology of f(R) Gravity in the Metric Variational Approach
Baojiu Li, John D. Barrow
We consider the cosmologies that arise in a subclass of f(R) gravity with f(R)=R+μ^{2n+2}/(-R)^{n} and -1<n<0 in the metric (as opposed to the Palatini) variational approach to der…
