Cosmology: theory [PDF]

open access: yesProceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP 2013), 2013
The discovery of 126 GeV Higgs boson and observations of no signs of new physics at the LHC implies that the Standard Model of elementary particles is a selfconsistent weakly-coupled effective field theory all the way up to the Planck scale without the ...

Teleparallel gravity: from theory to cosmology [PDF]

open access: yesReports on Progress in Physics, 2021
Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing attention to Einstein’s other theory of gravity. In this Review, we give a comprehensive introduction to how teleparallel geometry is developed as a gauge ...

News from the Swampland — constraining string theory with astrophysics and cosmology [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2023
Our current best guess for a unified theory of gravitation and quantum field theory (string theory) generically predicts a set of requirements for a consistently quantized theory, the Swampland criteria.

Quantum cosmology in f(Q) theory [PDF]

open access: yesClassical and quantum gravity, 2021
We use Dirac’s method for the quantization of constrained systems in order to quantize a spatially flat Friedmann–Lemaître–Robertson–Walker spacetime in the context of f(Q) cosmology.

Loop quantum cosmology: relation between theory and observations [PDF]

open access: yes, 2023
This chapter provides a review of the frameworks developed for cosmological perturbation theory in loop quantum cosmology, and applications to various models of the early universe including inflation, ekpyrosis and the matter bounce, with an emphasis on ...

Emergent cosmology from matrix theory [PDF]

open access: yesJournal of High Energy Physics, 2021
Matrix theory is a proposed non-perturbative definition of superstring theory in which space is emergent. We begin a study of cosmology in the context of matrix theory.

Cosmology with the Laser Interferometer Space Antenna [PDF]

open access: yesLiving Reviews in Relativity, 2022
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and ...

Superstring cosmology — a complementary review [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2023
In this review, a number of approaches to superstring cosmology which make use of key features which distinguish string theory from point particle theories are discussed, with particular emphasis on emergent scenarios.

Anomalies in physical cosmology [PDF]

open access: yesAnnals of Physics, 2022
The $\Lambda$CDM cosmology passes demanding tests that establish it as a good approximation to reality. The theory is incomplete, of course, and open issues are being examined in active research programs.
