Energy conditions in static, spherically symmetric spacetimes and effective geometries

Emmanuele Battista, Zi-Liang Wang

A logarithmic correction to Schwarzschild in static spherical symmetry obeys all classical energy conditions and serves as an effective exterior for horizon-bearing and horizonless compact objects.

Claims

C1strongest claim

Within this family, we select a particularly significant metric that incorporates a logarithmic correction to the Schwarzschild model and fulfills all standard energy criteria. Our analysis shows that this geometry can be interpreted as an effective exterior description for both horizon-bearing and horizonless compact objects, and suggests that it can potentially act, in certain regimes, as a black hole mimicker.

C2weakest assumption

The assumption that g_tt g_rr = -1 enables a systematic algorithm to generate solutions obeying the null energy condition; the paper states that non-constant products can signal null energy condition violation at horizons.

C3one line summary

A logarithmic correction to Schwarzschild in static spherical symmetry obeys all classical energy conditions and serves as an effective exterior for horizon-bearing and horizonless compact objects.
