New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Boosting GWs in Supersolid Inflation
Marco Celoria, Denis Comelli, Luigi Pilo +1
Inflation driven by a generic self-gravitating medium is an interesting alternative to study the impact of spontaneous spacetime symmetry breaking during a quasi de-Sitter phase, i…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
Adiabatic Media Inflation
Marco Celoria, Denis Comelli, Luigi Pilo +1
We study the dynamics of inflation driven by an adiabatic self-gravitating medium, extending the previous works on fluid and solid inflation. Such a class of media comprises perfec…
Formalism and Conserved Currents in Cosmology
Sabino Matarrese, Luigi Pilo, Rocco Rollo
The formalism, based on the counting of the number of e-folds during inflation in different local patches of the Universe, has been introduced several years ago as a simple an…
Self-gravitating -media
Marco Celoria, Denis Comelli, Luigi Pilo
We address the question whether a medium featuring , dubbed - medium, has to be necessarily a cosmological constant. By using effective field theory, we show that this…
Intrinsic Entropy Perturbations from the Dark Sector
Marco Celoria, Denis Comelli, Luigi Pilo
Perfect fluids are modeled by using an effective field theory approach which naturally gives a self-consistent and unambiguous description of the intrinsic non-adiabatic contributi…
Fluids, Superfluids and Supersolids: Dynamics and Cosmology of Self Gravitating Media
Marco Celoria, Denis Comelli, Luigi Pilo
We compute cosmological perturbations for a generic self-gravitating media described by four derivatively- coupled scalar fields. Depending on the internal symmetries of the action…
Effective Lagrangian for Quantum Black Holes
A. Buonanno, M. Gattobigio, M. Maggiore +2
We discuss the most general effective Lagrangian obtained from the assumption that the degrees of freedom to be quantized, in a black hole, are on the horizon. The effective Lagran…
