When Black Holes Can Wear Pants
Giacomo Cacciapaglia, Manuel Del Piano, Francesco Sannino +1
We investigate the conditions under which black hole fragmentation, the splitting of a black hole horizon into multiple smaller ones, may occur. The simplest realization is that of…
Completely asymptotically free chiral theories with scalars
Giacomo Cacciapaglia, Francesco Sannino, Sophie Wagner
We provide the conditions for complete asymptotic freedom for chiral gauge theories including scalars, as motivated by grand unified models. These are generalised Georgi-Glashow an…
Systems with Quantum Dimensions
Mikołaj Myszkowski, Mattia Damia Paciarini, Francesco Sannino
We propose quantum-mechanical systems in which the number of spatial dimensions is promoted to a dynamical quantum variable, making the effective dimension state-dependent. Interes…
Toward a unified view of agnostic parametrizations for deformed black holes
Manuel Del Piano, Ciro De Simone, Mattia Damia Paciarini +4
A variety of robust and effective descriptions have been devised to extract model-independent information about the fundamental properties of black holes from observational data wh…
Regular Spacetimes in the Effective Metric Description
Mattia Damia Paciarini, Mikołaj Myszkowski, Francesco Sannino +1
Over the past few decades, significant effort has been directed towards developing various regularized models for compact objects. Recently, a new observable-based parametrization…
Effective Metric Description of Charged Black Holes
Mattia Damia Paciarini, Manuel Del Piano, Stefan Hohenegger +1
Charged black holes arise as solutions of General Relativity (GR) coupled to Maxwell theory. As functions of the mass and charge, they can exhibit extremal behavior, in which case…
Effective Metric Description of 2+1 Dimensional Quantum Black Holes
Stefan Hohenegger, Mikolaj Myszkowski, Mattia Damia Paciarini +1
We develop an effective metric description of 2+1 dimensional black holes describing deviations from the classical Bañados-Teitelboim-Zanelli (BTZ) black hole. The latter is a clas…
Black Hole Shadow and other Observables away from the Horizon: Extending the Effective Metric Descriptions
Manuel Del Piano, Stefan Hohenegger, Francesco Sannino
In previous work we have developed a model-independent, effective description of quantum deformed, spherically symmetric and static black holes in four dimensions. The deformations…
Looking for Black Hole Morsels in Astrophysical Mergers via Hawking Radiation
Giacomo Cacciapaglia, Stefan Hohenegger, Francesco Sannino
Gravitational wave observation has provided numerous insights into the merger of astrophysical black holes. In contrast to other violent events (e.g. supernovae), they are, however…
Effective Metric Descriptions of Quantum Black Holes
Manuel Del Piano, Stefan Hohenegger, Francesco Sannino
In a recent work [arXiv:2307.13489 [gr-qc]], we have described spherically symmetric and static quantum black holes as deformations of the classical Schwarzschild metric that depen…
Renormalisation Group Methods for Effective Epidemiological Models
Stefan Hohenegger, Francesco Sannino
Epidemiological models describe the spread of an infectious disease within a population. They capture microscopic details on how the disease is passed on among individuals in vario…
Information Theory Unification of Epidemiological and Population Dynamics
Baptiste Filoche, Stefan Hohenegger, Francesco Sannino
We reformulate models in epidemiology and population dynamics in terms of probability distributions. This allows us to construct the Fisher information, which we interpret as the m…
