A Periodically Interacting Dark Sector: Signatures and Constraints from CMB and Cosmic Expansion Data
Marco Antonio Cardoso Alvarez, Micol Benetti, Leila Graef +1
We introduce a novel cosmological model that provides an effective description of the back-reaction of super-Hubble fluctuations on the cosmological background, a generic effect ex…
Multi-Matrix Quantum Mechanics, Collective Fields and Emergent Space
Yue Lei, Suddhasattwa Brahma, Robert Brandenberger
We study quantum mechanics of bosonic multi-matrix Lagragians in the collective field framework, with particular emphasis on three matrix models. We derive the effective Hamiltonia…
Inflationary Reheating to Preheating - A Personal Account
Robert Brandenberger, Jennie Traschen
This is a personal account of the early work that led to what is now known as the ``preheating stage" of inflationary cosmology. The broader applicability of the underlying instabi…
UV Luminosity Functions from HST and JWST: A Possible Resolution to the High-Redshift Galaxy Abundance Puzzle and Implications for Cosmic Strings
Mattéo Blamart, Adrian Liu, Robert Brandenberger +2
Recent observations of high redshift galaxies by the James Webb Space Telescope suggest the presence of a bright population of galaxies that is more abundant than predicted by most…
A Non-Inflationary Axion and ALP Misalignment Mechanism
Robert Brandenberger
Based on considerations of quantum gravity, global symmetries which lead to axions as pseudo Nambu-Goldstone bosons after low scale symmetry breaking cannot be exact at the Planck…
Why the DESI Results Should Not Be A Surprise
Robert Brandenberger
The recent DESI results provide increasing evidence that the density of dark energy is time-dependent. I will recall why, from the point of view of fundamental theory,, this result…
