New paper by researchers at CP3 on resolving the Hubble expansion rate problem of cosmology with New Early Dark Energy (a 1st order phase transition in the dark sector): https://t.co/qTAY7B6MXz
Can we resolve the Hubble tension with a first order phase transition in the early universe? See our paper: https://t.co/m486cvjXy9 Here the false vacuum energy of a scalar field provides a short burst of repulsion before it decays via the nucleation of true vacuum bubbles.
