Higher-curvature corrections and the endpoint of black hole evaporation in gravitational effective field theory
Lorens F. Niehof, Sjors Heefer, Andrea Fuster +1
The endpoint of black hole evaporation remains uncertain once the semiclassical description approaches the Planck scale. In this work we study late-stage evaporation within four-di…
New class of non-Einstein pp-wave solutions to quadratic gravity
Sjors Heefer, Lorens F. Niehof, Andrea Fuster
We obtain a new family of exact vacuum solutions to quadratic gravity that describe pp-waves with two-dimensional wave surfaces that can have any prescribed constant curvature. Whe…
Finsler Geometry, Spacetime & Gravity -- From Metrizability of Berwald Spaces to Exact Vacuum Solutions in Finsler Gravity
Sjors Heefer
This PhD dissertation covers a range of topics in Finsler geometry and Finsler gravity, most notably: (i) the characterization of Berwald spaces, (ii) pseudo-Riemann (non-)metrizab…
White Paper and Roadmap for Quantum Gravity Phenomenology in the Multi-Messenger Era
R. Alves Batista, G. Amelino-Camelia, D. Boncioli +101
The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put…
A Cosmological Unicorn Solution to Finsler Gravity
Sjors Heefer, Christian Pfeifer, Antonio Reggio +1
We present a new family of exact vacuum solutions to Pfeifer and Wohlfarth's field equation in Finsler gravity, consisting of Finsler metrics that are Landsbergian but not Berwaldi…
Finsler gravitational waves of -type and their observational signature
Sjors Heefer, Andrea Fuster
We introduce a new class of -type exact solutions in Finsler gravity closely related to the well-known pp-waves in general relativity. Our class contains most of the exact s…
Randers pp-waves
Sjors Heefer, Christian Pfeifer, Andrea Fuster
In this work we study Randers spacetimes of Berwald type and analyze Pfeifer and Wohlfarth's vacuum field equation of Finsler gravity for this class. We show that in this case the…
Relativistic compatibility of the interacting -Poincaré model and implications for the relative locality framework
Giulia Gubitosi, Sjors Heefer
We investigate the relativistic properties under boost transformations of the -Poincaré model with multiple causally connected interactions, both at the level of its formulation…
