Dark energy from primordial inflationary quantum fluctuations.
We show that current cosmic acceleration can be explained by an almost massless scalar field experiencing quantum fluctuations during primordial inflation. Provided its mass does not exceed the Hubble parameter today, this field has been frozen during the cosmological ages to start dominating the Universe only recently. By using supernovae data, completed with baryonic acoustic oscillations fro...
متن کاملNon-Thermal Dark Matter, High Energy Cosmic Rays and Late-Decaying Particles From Inflationary Quantum Fluctuations
It has been suggested that the origin of cosmic rays above the GZK limit might be explained by the decay of particles, X, with mass of the order of 1012 GeV. Generation of heavy particles from inflationary quantum fluctuations is a prime candidate for the origin of the decaying X particles. It has also been suggested that the problem of non-singular galactic halos might be explained if dark mat...
متن کاملDark energy: a quantum fossil from the inflationary Universe?
The discovery of dark energy (DE) as the physical cause for the accelerated expansion of the Universe is the most remarkable experimental finding of modern cosmology. However, it leads to insurmountable theoretical difficulties from the point of view of fundamental physics. Inflation, on the other hand, constitutes another crucial ingredient, which seems necessary to solve other cosmological co...
متن کاملDark Energy From Vacuum Fluctuations
The nature of the dark energy (DE) is one of the most outstanding problems of physical sciences today. Numerous and often ingenious attempts have been made to explain it, with multiple new papers appearing daily, yet no model proposed so far has gained a general acceptance. Modern approaches to the problem date from the pioneering papers by Zel’dovich [1], who was first to recognize the fundame...
متن کاملNon-Thermal WIMP Dark Matter, High Energy Cosmic Rays and Late-Decaying Particles From Inflationary Quantum Fluctuations
It has been suggested that the problem of non-singular galactic halos might be explained if dark matter originates non-thermally from the decay of massive particles Y , such that there is a free-streaming length of the order of 0.1Mpc. It has also been suggested that the origin of cosmic rays above the GZK limit might be explained by the decay of particles X with mX ≈ 1012 GeV. We consider the ...
