A charged scalar field can be used to extract energy from a charged black hole via superradiant scattering. A mirror-like or AdS boundary could lead the system to an instability. This is because the scalar fields are trapped outside the black hole and repeatedly amplified, there-fore ultimately the back-reaction on the black hole background will become non-negligible.
A charged scalar field...

I will talk about the effects of higher curvature corrections from Lovelock gravity on the phase structure of asymptotically AdS black holes, treating the cosmological constant as a thermodynamic pressure.

We show how a system of $N>>1$ horizonless conic singularities, with average opening angle at the horizon $\langle \Theta \rangle=2\pi$, can effectively approximate the geometry and the entropy of a semiclassical black hole. We test what happen to in-going informations in such a system, with a simple gedanken experiment: we consider a plane wave function in-going in this system of N conic...

I will discuss multisymplectic geometry and its application to finite spacetime regions. This allows one to perform a 3+1 decomposition where the spatial slice need not be a Cauchy surface. I show how this can lead to a modification of the symplectic structure, Hamilton's principle function, and momentum maps (conserved charges). Such modifications are in the form of boundary terms which can...

I will talk about the extension of general uncertainty principle (GUP) inspired black holes to the scenario of large spatial extradimensions (ADD).
