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…

Vortices and rotating solitons in ultralight dark matter

Philippe Brax, Patrick Valageas

The dynamics of ultralight dark matter with non-negligible self-interactions are determined by a nonlinear Schrödinger equation rather than by the Vlasov equation of collisionless…

A Minimal Axio-dilaton Dark Sector

Adam Smith, Maria Mylova, Philippe Brax +3

In scalar-tensor theories it is the two-derivative sigma-model interactions that like to compete at low energies with the two-derivative interactions of General Relativity (GR) $\u…

CMB Implications of Multi-field Axio-dilaton Cosmology

Adam Smith, Maria Mylova, Philippe Brax +3

Axio-dilaton models are among the simplest scalar-tensor theories that contain the two-derivative interactions that naturally compete at low energies with the two-derivative inter-…

Detecting dark matter oscillations with gravitational waveforms

Philippe Brax, Clare Burrage, Jose A. R. Cembranos +1

We consider the phase shift in the gravitational wave signal induced by fast oscillations of scalar dark matter surrounding binary systems, which could be probed by the future expe…

Scalaron dynamics from UV to IR

Philippe Brax, Pierre Vanhove

We consider a scenario where the scalaron of models is related to the volume modulus of string compactifications leaving only one scalar degree of freedom at low ener…
