Music for the holographic party
(Room 326, from
20180321 13:30 to
20180321 14:30)

Dear theoretical physicists:
The last edition of the holographic party was nice but once again the phonons didn't come and there was no music. We all know whose fault it is. So my proposal for this year is simple: let's not invite Lorentz. He has his temper so we shouldn't be too explicit . From past experiences we know that this is a nontrivial task, however I must remark that this is an absolute must if we want to come close to something which indeed looks like a real party.
Lately some people have been proposing a class of massive gravity holographic models which could do the job, I think we should try. It's about time.

Strong cosmic censorship in de Sitter space
(CFP Room  326, from

Recent work indicates that the strong cosmic censorship hypothesis is violated by nearly extremal ReissnerNordstromde Sitter black holes. It was argued that perturbations of such a black hole decay sufficiently rapidly that the perturbed spacetime can be extended across the Cauchy horizon as a weak solution of the equations of motion. In this paper we consider the case of Kerrde Sitter black holes. We find that, for any nonextremal value of the black hole parameters, there are quasinormal modes which decay sufficiently slowly to ensure that strong cosmic censorship is respected. Our analysis covers both scalar field and linearized gravitational perturbations.

Critical systems and conformal perturbation theory
(CFP Room  326, from
20180307 13:30 to
20180307 14:30)

Statistical systems near a classical critical point have been intensively studied both from theoretical and experimental points of view. In particular, correlation functions are of relevance in comparing theoretical models with the experimental data of real systems. In order to compute physical quantities near a critical point one needs to know the model at the critical (conformal) point. In this line, recent progresses in the knowledge of conformal field theories, through the conformal bootstrap, give the hope to get some interesting results also outside of the critical point.
In this talk I will review and clarify how, starting from the knowledge of the critical correlators, one can calculate in a safe way their behavior outside the critical point. The approach illustrated requires the model to be just scale invariant at the critical point. I will clarify the method by applying it to different kind of perturbations of the 2D and 3D Ising model, discussing their possible experimental applications and their relations with conformal bootstrap results.
