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…
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…
Surface Defects in -type Little String Theories
Baptiste Filoche, Stefan Hohenegger, Taro Kimura
-type Little String Theories (LSTs) are engineered from parallel M5-branes on a circle , probing a transverse background. Below t…
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…
