Axion-Induced Casimir Interaction Between Graphene Plates
Ahmad Alachkar, Philippe Brax, Pierre Brun
Axion dark matter may induce observable electromagnetic effects in resonant cavity systems and potentially lead to modifications of the Casimir interaction. In this context, graphe…
Finite size effects in DBI and Born-Infeld for screened spherically symmetric objects
Jose Beltrán Jiménez, Dario Bettoni, Philippe Brax +2
We study finite size effects on the linear response of spherically symmetric objects in Born-Infeld (BI) electromagnetism and Dirac-Born-Infeld (DBI) scalar field theories. Previou…
Updates on dipolar anisotropy in local measurements of the Hubble constant from Cosmicflows-4
Vincenzo Salzano, J. Beltrán Jiménez, Dario Bettoni +2
We investigate the angular anisotropy of the Hubble constant using the Cosmicflows-4 catalogue, with particular emphasis on three issues often treated only implicitly in the litera…
Weinberg's theorem, phantom crossing and screening
Philippe Brax
We consider models where the dilaton, seen as the pseudo-Goldstone boson of broken scale invariance, plays the role of dark energy. We revisit Weinberg's theorem and show that quan…
Casimir pressure with dissipation and quantum corrections from axion dark matter
Philippe Brax, Pierre Brun
We study the effects of the oscillating axion field present in our environment on the Casimir pressure between two metallic plates. We take into account the finite conductivity of…
Running Love Numbers and the Effective Field Theory of Gravity
Sergio Barbosa, Philippe Brax, Sylvain Fichet +1
Massive states produce higher derivative corrections to Einstein gravity in the infrared, which are encoded into operators of the Effective Field Theory (EFT) of gravity. These EFT…
