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…
On the 6th Mode in Massive Gravity
Marco Celoria, Denis Comelli, Luigi Pilo
Generic massive gravity models in the unitary gauge correspond to a self-gravitating medium with six degrees of freedom. It is widely believed that massive gravity models with six…
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…
