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…

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…
