Fisher Information and Dynamical Sampling I
Mattia Carrino, Stefan Hohenegger
Information theory is a powerful framework to capture aspects of dynamical systems with multiple degrees of freedom. Mathematically, the dynamics can be represented as a continuous…
Wall-crossing of Instantons on the Blow-up
Baptiste Filoche, Stefan Hohenegger, Taro Kimura
We study the instanton counting in four dimensional supersymmetric gauge theories on the blow-up of : we start by formulating the instanton moduli spa…
Probing Effective Black Hole Deformations
Stefan Hohenegger
In recent works, a framework has been developed to describe (quantum) deformed, spherically symmetric and static black holes in four dimensions. The key idea of this so-called Effe…
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…
