Embedding Gauss–Bonnet Scalarization Models in Higher Dimensional Topological Theories

Abstract: In the presence of appropriate non-minimal couplings between a scalar field and the curvature squared Gauss–Bonnet (GB) term, compact objects such as neutron stars and black holes (BHs) can spontaneously scalarize, becoming a preferred vacuum. Such strong gravity phase transitions have attracted considerable attention recently. The non-minimal coupling functions that allow this mechanism are, however, always postulated ad hoc. Here, we point out that families of such functions naturally emerge in the context o… Show more

“…A review of theories of this kind and their comparison with cosmographic tests are given in the work [6]. A large survey of theories with Lagrangians, nonlinear in curvature and containing the Gauss-Bonnet invariant, is given in the papers [7,8], and a number of solutions were obtained in works [9][10][11][12][13][14]. Theories with Lagrangians of the form f (ϕ, R), and their relationship with inflation and modern accelerated expansion, are considered in the work [15].…”
