New model of axion monodromy inflation and its cosmological implications
Yi-Fu Cai, Fang Chen, Elisa G. M. Ferreira +1
We propose a new realization of axion monodromy inflation in which axion monodromy arises from torsional cycles in a type IIB compactification. A class of monomial potentials is ob…
Evidence for interacting dark energy from BOSS
Elisa G. M. Ferreira, Jerome Quintin, André A. Costa +2
The result presented by the BOSS-SDSS Collaboration measuring the baryon acoustic oscillations of the Lyman- forest from high-redshift quasars indicates a departure from…
Matter creation in a nonsingular bouncing cosmology
Jerome Quintin, Yi-Fu Cai, Robert H. Brandenberger
We examine reheating in the two-field matter bounce cosmology. In this model, the universe evolves from a matter-dominated phase of contraction to an Ekpyrotic phase of contraction…
Nonsingular bouncing cosmologies in light of BICEP2
Yi-Fu Cai, Jerome Quintin, Emmanuel N. Saridakis +1
We confront various nonsingular bouncing cosmologies with the recently released BICEP2 data and investigate the observational constraints on their parameter space. In particular, w…
