Quasinormal modes are eigenmodes of dissipative systems. Perturbations of classical
gravitational backgrounds involving black holes or branes naturally lead to quasinormal …

Lovelock theory is a natural extension of Einstein theory of gravity to higher dimensions, and
it is of great interest in theoretical physics as it describes a wide class of models. In …

Astrophysical black hole candidates, although long thought to have a horizon, could be
horizonless ultracompact objects. This intriguing possibility is motivated by the black hole …

In recent years, there has been considerable interest in theories formulated in anti-de Sitter
(AdS) spacetime. However, AdS spacetime fails to be globally hyperbolic, so a classical field …

We investigate the classical stability of higher-dimensional Schwarzschild black holes with
respect to linear perturbations in the framework of a gauge-invariant formalism for …

Roughly speaking, classical statistical physics is the branch of theoretical physics that aims
to account for the thermal behaviour of macroscopic bodies in terms of a classical …

It was recently shown that the von Neumann algebras of observables dressed to the mass of
a Schwarzschild-AdS black hole or an observer in de Sitter are Type II, and thus admit well …

We study spherically symmetric configurations of the quadratic f (R) gravity [f (R)= RR 2/6 μ
2]. In the case of a purely gravitational system, we have fully investigated the global …

The aims of this chapter are to review some aspects of determinism that are familiar to
physicists but are little discussed in the philosophical literature and to show how these …

A bstract We study hairy black holes in Einstein-Maxwell-complex scalar theory in four-
dimensional asymptotically global anti-de Sitter (AdS) spacetime when the Robin boundary …
