Thermodynamics of perfect fluids from scalar field theory
Guillermo Ballesteros, Denis Comelli, Luigi Pilo
The low-energy dynamics of relativistic continuous media is given by a shift-symmetric effective theory of four scalar fields. These scalars describe the embedding in spacetime of…

Massive and modified gravity as self-gravitating media
Guillermo Ballesteros, Denis Comelli, Luigi Pilo
We study the effective field theory that describes the low-energy physics of self-gravitating media. The field content consists of four derivatively coupled scalar fields that can…
