Asymptotically safe quantum gravity and its phenomenology -- a review
Astrid Eichhorn
Asymptotically safe quantum gravity is an approach to quantum gravity. It is based on the premise that quantum field theory can describe the quantum nature of gravity in our univer…
Non-uniqueness of boundary-value problems in Renormalization Group flows
Astrid Eichhorn, Zois Gyftopoulos, Aaron Held
The Renormalization Group flow connects microscopic to macroscopic descriptions of a system and is therefore typically considered as an initial-value problem. Motivated by situatio…
Application of positivity bounds in asymptotically safe gravity
Astrid Eichhorn, Andreas Odgaard Pedersen, Marc Schiffer
Positivity bounds are bounds on the Wilson coefficients of an effective field theory. They hold, if the ultraviolet completion satisfies unitarity, microcausality, locality and Lor…
Light fermions in color: why the quark mass is not the Planck mass
Gustavo P. de Brito, Astrid Eichhorn, Shouryya Ray
We investigate whether quantum gravity fluctuations can break chiral symmetry for fermions that are charged under a and an gauge symmetry and thus closely r…
