Evolving Dark Energy with w Deviating from -1
Lawrence J. Hall, Yasunori Nomura, Steven J. Oliver
Theories of evolving quintessence are constructed that generically lead to deviations from the w = -1 prediction of non-evolving dark energy. The small mass scale that governs evol…

Acceleressence: Dark Energy from a Phase Transition at the Seesaw Scale
Z. Chacko, Lawrence J. Hall, Yasunori Nomura
Simple models are constructed for "acceleressence" dark energy: the latent heat of a phase transition occurring in a hidden sector governed by the seesaw mass scale v^2/M_Pl, where…
