Description
A compelling unified model of dark energy and early dark energy (EDE) is presented, using a scalar field with a simple exponential runaway potential, in the context of alpha-attractors. The field is originally trapped at an enhanced symmetry point, subsequently thaws to become successful EDE and eventually slow-rolls to become dark energy. EDE ameliorates the observed Hubble tension. Emphasis is put on concrete predictions of both EDE and dark energy to be tested in the near future.
