Tackling Loopholes in Experimental Tests of Bell's Inequality
David I. Kaiser
Bell's inequality sets a strict threshold for how strongly correlated the outcomes of measurements on two or more particles can be, if the outcomes of each measurement are independ…
Nonminimal Couplings and the Forgotten Field of Axion Inflation
Evan McDonough, Alan H. Guth, David I. Kaiser
We study the multifield dynamics of axion models nonminimally coupled to gravity. As usual, we consider a canonical symmetry-breaking model in which the axion is the phase o…
The First Three Seconds: a Review of Possible Expansion Histories of the Early Universe
Rouzbeh Allahverdi, Mustafa A. Amin, Asher Berlin +23
It is commonly assumed that the energy density of the Universe was dominated by radiation between reheating after inflation and the onset of matter domination 54,000 years later. W…
Effective theories for a nonrelativistic field in an expanding universe: Induced self-interaction, pressure, sound speed, and viscosity
Borna Salehian, Mohammad Hossein Namjoo, David I. Kaiser
A massive, nonrelativistic scalar field in an expanding spacetime is usually approximated by a pressureless perfect fluid, which leads to the standard conclusion that such a field…
Time-Scales for Nonlinear Processes in Preheating after Multifield Inflation with Nonminimal Couplings
Jorinde van de Vis, Rachel Nguyen, Evangelos I. Sfakianakis +2
We have conducted extensive lattice simulations to study the post-inflation dynamics of multifield models involving nonminimal couplings. We explore the parameter dependence of pre…
