Nonlinear cosmological consistency relations and effective matter stresses
Guillermo Ballesteros, Lukas Hollenstein, Rajeev Kumar Jain +1
We propose a fully nonlinear framework to construct consistency relations for testing generic cosmological scenarios using the evolution of large scale structure. It is based on th…
Zero-point quantum fluctuations in cosmology
Lukas Hollenstein, Maud Jaccard, Michele Maggiore +1
We re-examine the classic problem of the renormalization of zero-point quantum fluctuations in a Friedmann-Robertson-Walker background. We discuss a number of issues that arise whe…
Resonant magnetic fields from inflation
Christian T. Byrnes, Lukas Hollenstein, Rajeev Kumar Jain +1
We propose a novel scenario to generate primordial magnetic fields during inflation induced by an oscillating coupling of the electromagnetic field to the inflaton. This resonant m…
Early dark energy from zero-point quantum fluctuations
Michele Maggiore, Lukas Hollenstein, Maud Jaccard +1
We examine a cosmological model with a dark energy density of the form , where is the component that accelerates the Hubble expansion at late times a…
