In this work, we provide consistent compactifications of Einstein-Maxwell and Einstein-
Maxwell-Lovelock theories on direct product spacetimes of the form MD= M d× K p, where K …

Four-dimensional homogeneous static and rotating black strings in dynamical Chern–
Simons modified gravity, with and without torsion, are presented. Each solution is supported …

We show that the compactified extra dimension and the emergence of the island can provide
clues about quantum gravity because their combination can solve the deepest puzzles of …

In this paper we construct new exact solutions in Einstein–Gauss–Bonnet and Lovelock
gravity, describing asymptotically flat black strings. The solutions exist also under the …

We construct analytical solutions describing black holes and black strings in the Einstein SU
(N)-nonlinear sigma model in (3+ 1) dimensions. This construction is carried out using the …

We consider a perturbative Gauss-Bonnet term supplementing the Einstein-Hilbert action
and evaluate its effect on the spectrum of the scalar mode that triggers the Gregory …

In this paper, we construct compactifications of generic, higher-curvature Lovelock theories
of gravity over direct product spaces of the type MD= M d× S p, with D= d+ p and d≥ 5 …

This work is devoted to provide a way of representing 4 D spherically symmetric and static
compact stellar configurations into a 5 D space–time, using the black string framework. We …

Parallel to the new developments in Lovelock gravity, we introduce a general solution to the
pure-Lovelock theory in 3+ 1-dimensional static and spherically symmetric spacetime. The …

A bstract We consider a class of ansätze for the construction of exact solutions of the
Einstein-nonlinear σ-model system with an arbitrary cosmological constant in (3+ 1) …
