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…
CMB and Matter Power Spectra of Early f(R) Cosmology in Palatini Formalism
Baojiu Li, Ming-Chung Chu
We calculate in this article the CMB and matter power spectra of a class of early cosmologies, which takes the form of . Unlik…
Constraints on f(R) Cosmology in the Palatini Formalism
Baojiu Li, K. C. Chan, M. -C. Chu
In this work we derive the covariant and gauge invariant perturbation equations in general theories of gravity in the Palatini formalism to linear order and calculate the co…
Big Bang Nucleosynthesis with an Evolving Radion in the Brane World Scenario
Baojiu Li, Ming-Chung Chu
We consider the big bang nucleosynthesis (BBN) in the Brane world scenario, where all matter fields are confined on our 3-brane and the radion of the Brane evolves cosmologically.…
Dark Energy as a Signature of Extra Dimensions
Baojiu Li, Ming-Chung Chu, Kai-Chung Cheung +1
One of the most important and surprising discoveries in cosmology in recent years is the realization that our Universe is dominated by a mysterious dark energy, which leads to an a…
