TL;DR

This paper presents explicit stationary BPS solutions in four-dimensional N=2 supergravity with R^2-interactions, highlighting the construction process and the impact of higher-curvature terms on spacetime properties.

Contribution

It provides a method to construct BPS solutions with higher-curvature interactions and discusses their non-static nature and horizon existence.

Findings

Higher-curvature interactions lead to non-static solutions.

Solutions can be constructed iteratively.

Horizons may exist in multi-centered configurations.

Abstract

We discuss explicit examples of BPS solutions in four-dimensional N=2 supergravity with R^2-interactions. We demonstrate how to construct solutions by iteration. Generically, the presence of higher-curvature interactions leads to non-static spacetime line elements. We comment on the existence of horizons for multi-centered solutions.
