Asymptotic freedom of Yang–Mills theory with gravity
S Folkerts, DF Litim, JM Pawlowski - Physics Letters B, 2012 - Elsevier
We study the behaviour of Yang–Mills theory under the inclusion of gravity. In the weak-gravity
limit, the running gauge coupling receives no contribution from the gravitational sector, if …

Human episodic memory retrieval is accompanied by a neural contiguity effect
S Folkerts, U Rutishauser… - Journal of Neuroscience, 2018 - Soc Neuroscience
Cognitive psychologists have long hypothesized that experiences are encoded in a temporal
context that changes gradually over time. When an episodic memory is retrieved, the state …

Physics of trans-Planckian gravity
We study the field theoretical description of a generic theory of gravity flowing to Einstein
general relativity in IR. We prove that, if ghost-free, in the weakly-coupled regime such a theory …

[HTML][HTML] Axion Dark Matter and Planck favor non-minimal couplings to gravity
Constraints on inflationary scenarios and isocurvature perturbations have excluded the
simplest and most generic models of dark matter based on QCD axions. Considering non-…

On ghosts in theories of self-interacting massive spin-2 particles
S Folkerts, A Pritzel, N Wintergerst - arXiv preprint arXiv:1107.3157, 2011 - arxiv.org
We consider general theories of a massive spin-2 particle $h_{\mu\nu}$ on a Minkowski
background. A decomposition of $h_{\mu\nu}$ in terms of helicity eigenstates allows us to …

Massive spin-2 theories
S Folkerts, C Germani, N Wintergerst - arXiv preprint arXiv:1310.0453, 2013 - arxiv.org
We give an introduction to massive spin-2 theories and the problem of their non-linear
completion. We review the Boulware-Deser ghost problem and two ways to circumvent classic no-…

Non-perturbative gravity at different length scales
S Folkerts - 2013 - inis.iaea.org
In this thesis, we investigate different aspects of gravity as an effective field theory. Building
on the arguments of self-completeness of Einstein gravity, we argue that any sensible theory, …
