Cosmology from group field theory formalism for quantum gravity. [PDF]

open access: yesPhysical Review Letters, 2013
We identify a class of condensate states in the group field theory (GFT) formulation of quantum gravity that can be interpreted as macroscopic homogeneous spatial geometries.

Loop Quantum Cosmology: A cosmological theory with a view

open access: yesJournal of Physics: Conference Series, 2011
Loop Quantum Gravity is a background independent, nonperturbative approach to the quantization of General Relativity. Its application to models of interest in cosmology and astrophysics, known as Loop Quantum Cosmology, has led to new and exciting views of the gravitational phenomena that took place in the early universe, or that occur in spacetime ...

Late-time cosmology in (phantom) scalar-tensor theory: Dark energy and the cosmic speed-up [PDF]

open access: yes, 2004
We consider late-time cosmology in a (phantom) scalar-tensor theory with an exponential potential, as a dark energy model with equation of state parameter close to -1 (a bit above or below this value).

Viscous Cosmology for Early- and Late-Time Universe [PDF]

open access: yes, 2017
From a hydrodynamicist’s point of view the inclusion of viscosity concepts in the macroscopic theory of the cosmic fluid would appear most natural, as an ideal fluid is after all an abstraction (exluding special cases such as superconductivity).

Cosmology at the end of the world [PDF]

open access: yes, 2019
In the last two decades the anti-de Sitter/conformal field theory (AdS/CFT) correspondence has emerged as a focal point of many research interests. In particular, it functions as a stepping stone to a still-missing full quantum theory of gravity. In this
