Description

We will present several exact solutions of Entangled Relativity, a recent general theory of relativity that is more parsimonious in terms of constants and natural units than General Relativity, while still recovering its well-tested phenomenology. These solutions range from spherical black holes to traversable wormholes that satisfy the Null Energy Conditions, including slowly rotating charged black holes and compact objects with scalar charge embedded in external electromagnetic fields à la Melvin. We will also explain why the ratio between R and the on-shell matter Lagrangian, which defines a new gravitational scalar degree of freedom in the theory, is always well-defined and finite.

The talk will be based on results from publications 2407.17846, 2411.09327, 2502.13829, as well as on a spin-off of the findings presented in 2502.07206.
