The wide applications of higher dimensional gravity and gauge/gravity duality have fuelled
the search for new stationary solutions of the Einstein equation (possibly coupled to matter) …

We present a first-principles derivation of the main results of the Kerr/CFT correspondence
and its extensions using only tools from gravity and quantum field theory. Firstly, we review …

These lecture notes are intended for starting PhD students in theoretical physics who have a
working knowledge of General Relativity. The four topics covered are: Surface charges as …

A bstract We study the connection between many-body quantum chaos and energy
dynamics for the holographic theory dual to the Kerr-AdS black hole. In particular, we …

A bstract We examine the thermodynamics of a near-extremal Kerr black hole, and
demonstrate that the geometry behaves as an ordinary quantum system with a vanishingly …

Any spacetime containing a degenerate Killing horizon, such as an extremal black hole,
possesses a well-defined notion of a near-horizon geometry. We review such near-horizon …

The superradiant scattering of a scalar field with frequency and angular momentum (ω, m)
by a near-extreme Kerr black hole with mass and spin (M, J) was derived in the seventies by …

A bstract Black holes in anti-de Sitter (AdS) backgrounds play a pivotal role in the
gauge/gravity duality where they determine, among other things, the approach to equilibrium …

It has been shown recently that the strong cosmic censorship conjecture is violated by near-
extremal Reissner–Nordström–de Sitter black holes. We investigate whether the introduction …

Gravitational-wave astronomy can give us access to the structure of black holes, potentially
probing microscopic or even Planckian corrections at the horizon scale, as those predicted …
