Contribution

It introduces a numerical method to analyze black hole solutions in a low energy string theory with Gauss-Bonnet terms, uncovering non-trivial internal topologies.

Findings

Internal black hole regions exhibit non-trivial topology.

Numerical solutions inside and outside the event horizon are obtained.

The study advances understanding of black hole structure in string theory.

Abstract

Black holes are studied in the frames of superstring theory using a non-trivial numerical integration method. A low energy string action containing graviton, dilaton, Gauss-Bonnet and Maxwell contributions is considered. Four-dimensional black hole solutions are studied inside and outside the event horizon. The internal part of the solutions is shown to have a non-trivial topology.
