Multi-scale Constraints on Scalar-Field couplings to Matter: The Geodetic and Frame-Dragging Effects

Autor: Benisty, David, Brax, Philippe, Davis, Anne-Christine

The impact of light scalars coupled conformally and disformally to matter on the geodetic and frame-dragging (FD) precessions is calculated. For larger frequencies the disformal interaction becomes increasingly relevant. We use several satellite expe

Relativistic locality can imply subsystem locality

Autor: Di Biagio, Andrea, Howl, Richard, Brukner, Časlav, Rovelli, Carlo, Christodoulou, Marios

Locality is a central notion in modern physics, but different disciplines understand it in different ways. Quantum field theory focusses on relativistic locality, enforced by microcausality, while quantum information theory focuses on subsystem local

Cosmological implications of generalized holonomy corrections

Autor: Renevey, Cyril, Martineau, Killian, Barrau, Aurélien

Publikováno v: Physical Review D. 105

Most of the phenomenology of loop quantum gravity in the cosmological sector is based on the so-called holonomy correction to the Hamiltonian constraint. It straightforwardly modifies the Friedmann equations. In this work, we investigate the influenc

Predictions from the logotropic model: The universal surface density of dark matter halos and the present proportions of dark matter and dark energy

Autor: Chavanis, Pierre-Henri

Publikováno v: Phys.Dark Univ.

The logotropic model [P.H. Chavanis, Eur. Phys. J. Plus {\bf 130}, 130 (2015)] may be an interesting alternative to the $\Lambda$CDM model. It is able to account for the present accelerating expansion of the universe while solving at the same time th

Mean field flow equations and asymptotically free scalar fields

Autor: Kopper, Christoph

The flow equations of the renormalisation group permit to analyse the perturbative $n$-point functions of renormalisable quantum field theories. Rigorous bounds implying renormalisablility allow to control large momentum behaviour, infrared singulari

We study the dynamics of unstable Reissner-Nordstr\"om anti-de Sitter black holes under charged scalar field perturbations in spherical symmetry. We unravel their general behavior and approach to the final equlibrium state. In the first part of this
