The Serendipitous Axiodilaton: A Self-Consistent Recombination-Era Solution to the Hubble Tension
Adam Smith, Maria Mylova, Carsten van de Bruck +2
Axio-dilaton cosmology provides a minimal benchmark model for both Dark Matter (DM) and Dark Energy (DE) that is well motivated by fundamental physics. The axion and dilaton arise…
Dynamical Dark Energy Meets Varying Electron Mass: Implications for Phantom Crossing and the Hubble Constant
Adam Smith, Emre Özülker, Eleonora Di Valentino +1
We investigate the interplay between varying electron mass () and dynamical dark energy by analysing the Chevallier-Polarski-Linder (CPL) parametrization and its non-crossing…
Screened Axio-dilaton Cosmology: Novel Forms of Early Dark Energy
Adam Smith, Philippe Brax, Carsten van de Bruck +2
We study the cosmology of multi-field Dark Energy, using a well-motivated axio-dilaton model that contains the minimal number of fields to have the 2-derivative sigma-model interac…
