Imperfect fluid description of scalar-tensor gravity and an application to the GR limit

Title: Imperfect fluid description of scalar-tensor gravity and an application to the GR limit

Abstract:
Scalar-tensor gravity can be described as general relativity plus an effective imperfect fluid corresponding to the scalar field degree of freedom of this class of theories. A symmetry of electrovacuum Brans-Dicke gravity translates into a symmetry of the corresponding effective fluid. We present the formalism and an application to an anomaly in the limit of Brans-Dicke to Einstein gravity, and outline a possible application to the thermodynamics of spacetime.
