The case for a positive cosmological Λ-term

V Sahni, A Starobinsky - International Journal of Modern Physics D, 2000 - World Scientific
Recent observations of Type 1a supernovae indicating an accelerating universe have once
more drawn attention to the possible existence, at the present epoch, of a small positive Λ …

Cosmological constant—the weight of the vacuum

T Padmanabhan - Physics reports, 2003 - Elsevier
Recent cosmological observations suggest the existence of a positive cosmological constant
Λ with the magnitude Λ (Gℏ/c3)≈ 10− 123. This review discusses several aspects of the …

Evolution of the scale factor with a variable cosmological term

JM Overduin, FI Cooperstock - Physical Review D, 1998 - APS
The evolution of the scale factor a (t) in Friedmann models (those with zero pressure and a
constant cosmological term Λ) is well understood, and elegantly summarized in the review of …

Steep inflation followed by Born–Infeld reheating

M Sami, N Dadhich, T Shiromizu - Physics Letters B, 2003 - Elsevier
We discuss a model in which high energy brane corrections allow a single scalar field to
describe inflation at early epochs and quintessence at late times. The reheating mechanism …

[HTML][HTML] The accelerating universe in brane-world cosmology

MD Maia, EM Monte, JMF Maia - Physics Letters B, 2004 - Elsevier
The standard Friedmann universe embedded in a five-dimensional bulk with constant
curvature is examined as a brane-world with the extrinsic curvature derived directly from …

Nonsingular models with a variable cosmological term

JM Overduin - The Astrophysical Journal, 1999 - iopscience.iop.org
The weight of observational evidence is now converging on a nonzero value for the
cosmological term Λ. At the same time, theorists are increasingly exploring the possibility …

Probing extra dimensions through cosmological observations of dark energy

R Jalalzadeh, S Jalalzadeh, B Malekolkalami - Physics of the Dark …, 2023 - Elsevier
We investigate the isometrically embedded Bianchi type-V cosmology braneworld model in
a D-dimensional bulk space. The model provides a fluid of geometric dark energy (GDE) …

Studying the decay of the vacuum energy with the observed density fluctuation spectrum

R Opher, A Pelinson - Physical Review D—Particles, Fields, Gravitation, and …, 2004 - APS
We investigate here models that suggest that the vacuum energy decays into cold dark
matter (CDM) and show that the density fluctuation spectrum obtained from the cosmic …
