The general parametrization for spacetimes of spherically symmetric Lorentzian, traversable
wormholes in an arbitrary metric theory of gravity is presented. The parametrization is similar …

Quasinormal modes of a two-parameter family of Lorentzian wormhole spacetimes, which
arise as solutions in a specific scalar-tensor theory associated with braneworld gravity, are …

A particle moving with variable acceleration in the flat space-time affects the self-force due to
outgoing radiation. The gravitational fields bring an additional contribution to self-force due …

In this paper we construct new wormhole solutions of Lovelock theories in vacuum, when the
coupling constants are such that all the maximally symmetric solutions coincide, extending …

We study the massive scalar field of a charged particle held at rest in conical thin-shell
spacetimes with one or two asymptotic regions. Resonant and stable scalar Green's …

We consider the arbitrarily coupled field and self-force of a static massless scalar charge in
cylindrical spacetimes with one or two asymptotic regions, with the only matter content …

This doctoral thesis explores advanced concepts in theoretical physics, focusing on
asymptotically Anti-de Sitter (AdS) rotating black holes and wormholes within the framework …
