On the one hand, inflation is an extremely convincing scenario: it solves most cosmological paradoxes and generates fluctuations that became the seeds for the growth of structures. It, however, suffer...
Observational constraints on Chaplygin cosmology in a braneworld scenario with induced gravity and curvature effect
Observational constraints Chaplygin cosmology braneworld scenario
2010/12/27
We study cosmological dynamics and late-time evolution of an extended induced gravity braneworld scenario. In this scenario, curvature effects are taken into account via the Gauss-Bonnet term in the ...
High-order quantum back-reaction and quantum cosmology with a positive cosmological constant
High-order quantum back-reaction quantum cosmology
2010/12/27
When quantum back-reaction by fluctuations, correlations and higher moments of a state becomes strong, semiclassical quantum mechanics resembles a dynamical system with a high-dimensional phase space....

Non-archimedean quantum cosmology tachyonic inflation
2010/12/27
We review the relevance of quantum rolling tachyons and corresponding inflation scenario in the frame of the standard, $p$-adic and adelic minisuperspace quantum cosmology. The field theory of tachyon...
Inflation in Entropic Cosmology: Primordial Perturbations and non-Gaussianities
Entropic Cosmology Primordial Perturbations non-Gaussianities

We investigate thermal inflation in double-screen entropic cosmology. We find that its realization is general, resulting from the system evolution from non-equilibrium to equilibrium. Furthermore, goi...

Quiescent cosmology final state universe

It has long been a primary objective of cosmology to understand the apparent isotropy in our universe and to provide a mathematical formulation for its evolution. A school of thought for its explanati...
