Starobinsky-inflation in asymptotically safe shift-symmetric scalar-tensor theory
Benjamin Koch, Cristobal Laporte, Frank Saueressig
We investigate the constraining power of scalaron-driven inflation on asymptotically safe scalar-tensor theories. Starting from a Horndeski-type theory and applying a renormalizati…
Equivalence of scalar-tensor theories and scale-dependent gravity
Philipp Neckam, Christian Käding, Benjamin Koch +4
We present a novel equivalence between scale-dependent gravity and scalar-tensor theories that have only a single scalar field with a canonical kinetic term in the Einstein frame a…
Casimir Effect and Gravitational Balance: a Search for Stable Configurations
Leonardo Bellinato Giacomelli, Benjamin Koch, Iva Lovrekovic +1
In this study, we examine the role of the repulsive Casimir force in counteracting the gravitational contraction of a thin spherically symmetric shell. Our main focus is to explore…
A Universe from a Lagrangian Fixed Point
Pedro D. Alvarez, Benjamin Koch, Ali Riahinia +1
In this paper, we investigate the theoretical possibility that a Lagrangian fixed point, when applied to cosmological models, can drive dynamical evolution towards a bouncing unive…
Preliminary test of cosmological models in the scale-dependent scenario
A. Hernández-Arboleda, Á. Rincón, B. Koch +2
In the present work, we study for the first time a scale--dependent gravitational theory in a cosmological context in a matter--dominated era. In particular, starting from the Eins…
