String-induced vacuum decay and its gravitational wave signatures

Aleksandr Chatrchyan, Florian Niedermann, Phoebe Richman-Taylor

False vacuum decay typically proceeds via the nucleation of spherical bubbles of true vacuum, described by symmetric field configurations in Euclidean time. In this work, we…

Confronting Cold New Early Dark Energy and its Equation of State with Updated CMB, Supernovae, and BAO Data

Aleksandr Chatrchyan, Florian Niedermann, Vivian Poulin +1

Cold New Early Dark Energy (Cold NEDE) addresses the Hubble tension through a triggered vacuum phase transition in the dark sector. In this paper, we constrain a phenomenological f…
