Dark Energy from Time Crystals
Laura Mersini-Houghton
In this work, we analyze a scalar field model which gives rise to stable bound states in field space characterized by nonzero motion that breaks the underlying time translation sym…
Report of the Topical Group on Cosmic Probes of Fundamental Physics for for Snowmass 2021
Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang +118
Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probe…
Antioscillons
Laura Mersini-Houghton
This proceeding is based on a talk I gave at the 13th Marcel Grossmann Meeting in Stockholm Sweden, on the role of topology on bubble collisions.
Cosmological Implications of the String Theory Landscape
Laura Mersini-Houghton
Progress in string theory has resulted in a whole landscape of vacua solutions.In this talk I describe a proposal for exploring the cosmological implications of the landscape, base…
A First Glimpse of String Theory in the Sky?
Steen Hannestad, Laura Mersini-Houghton
We propose a new method for identifying new physics imprints on present observational data in cosmology whereby signatures of string theory are clearly distinguished from imprints…
Does the Low CMB Quadrupole Provide a New Cosmic Coincidence Problem ?
Alessandro Melchiorri, Laura Mersini-Houghton
We point out that the recent WMAP findings of a suppressed large scale power in the Cosmic Microwave Background anisotropy power spectrum, if of cosmological origin, make the case…
