Cosmological Stasis from a Single Annihilating Particle Species: Extending Stasis Into the Thermal Domain
Jonah Barber, Keith R. Dienes, Brooks Thomas
It has recently been shown that extended cosmological epochs can exist during which the abundances associated with different energy components remain constant despite cosmological…
Cosmological Stasis from Dynamical Scalars: Tracking Solutions and the Possibility of a Stasis-Induced Inflation
Keith R. Dienes, Lucien Heurtier, Fei Huang +2
It has recently been realized that many theories of physics beyond the Standard Model give rise to cosmological histories exhibiting extended epochs of cosmological stasis. During…
Betwixt Annihilation and Decay: The Hidden Structure of Cosmological Stasis
Jonah Barber, Keith R. Dienes, Brooks Thomas
Stasis is a unique cosmological phenomenon in which the abundances of different energy components in the universe (such as matter, radiation, and vacuum energy) each remain fixed e…
Conversations and Deliberations: Non-Standard Cosmological Epochs and Expansion Histories
Brian Batell, Keith R. Dienes, Brooks Thomas +17
This document summarizes the discussions which took place during the PITT-PACC Workshop entitled "Non-Standard Cosmological Epochs and Expansion Histories," held in Pittsburgh, Pen…
