Towards black-hole horizons and geodesic focusing in causal sets
Astrid Eichhorn, Pedro Gamito, Nawder Stokes
The event horizon of a black hole is arguably the most dramatic manifestation of the fact that in General Relativity, causal structure is dynamical and spacetimes can be separated…
Towards theory constraints on ultralight dark matter from quantum gravity
Gabriel Assant, Astrid Eichhorn, Benjamin Knorr
Ultralight scalar dark matter may couple to the Standard Model through dimension-five operators that contain the field-strength tensors of the gauge interactions. Recent progress i…
Strong breaking of black-hole uniqueness from coexisting scalarization mechanisms
Astrid Eichhorn, Pedro G. S. Fernandes, Lidia Marino
Black-hole uniqueness, i.e., the statement that all stationary vacuum black holes in the universe are described by the Kerr solution, is expected to break in theories beyond Genera…
Towards a quantitative characterization of gravitational universality classes for order-4 random tensor models
Alicia Castro, Astrid Eichhorn, Razvan Gurau
Random tensor models can be used as combinatorial devices to generate Euclidean dynamical triangulations. A physical continuum limit of dynamical triangulations requires a suitable…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
