TL;DR

This paper explores how the Gauss-Bonnet term influences the growth rate of holographic complexity in various black hole geometries, comparing different conjectures and analyzing late-time behaviors in higher curvature gravity.

Contribution

It provides a detailed analysis of the impact of Gauss-Bonnet corrections on holographic complexity growth across different horizon curvatures and compares multiple complexity proposals.

Findings

Gauss-Bonnet term suppresses complexity growth for flat and spherical horizons.

Effect of Gauss-Bonnet term on hyperbolic horizons may be opposite to expectations.

Different volume functionals show varied behaviors at late times in higher curvature theories.

Abstract

We study the effect of the Gauss-Bonnet term on the complexity growth rate of dual field theory using the "Complexity--Volume" (CV) and CV2.0 conjectures. We investigate the late time value and full time evolution of the complexity growth rate of the Gauss-Bonnet black holes with horizons with zero curvature ($k=0$), positive curvature ($k=1$) and negative curvature ($k=-1$) respectively. For the $k=0$ and $k=1$ cases we find that the Gauss-Bonnet term suppresses the growth rate as expected, while in the $k=-1$ case the effect of the Gauss-Bonnet term may be opposite to what is expected. The reason for it is briefly discussed, and the comparison of our results to the result obtained by using the "Complexity--Action" (CA) conjecture is also presented. We also briefly investigate two proposals applying some generalized volume functionals dual to the complexity in higher curvature gravity theories, and find their behaviors are different for $k=0$ at late times.
