Tame Embeddings, Volume Growth, and Complexity of Moduli Spaces
Thomas W. Grimm, David Prieto, Mick van Vliet
Quantum gravity is expected to impose constraints on the moduli spaces of massless fields that can arise in effective quantum field theories. A recent proposal asserts that the asy…

A Reduction Algorithm for Cosmological Correlators: Cuts, Contractions, and Complexity
Thomas W. Grimm, Arno Hoefnagels, Mick van Vliet
Cosmological correlators are fundamental observables in an expanding universe and are highly non-trivial functions even at tree-level. In this work, we uncover novel structures in…

On the Complexity of Quantum Field Theory
Thomas W. Grimm, Mick van Vliet
We initiate a study of the complexity of quantum field theories (QFTs) by proposing a measure of information contained in a QFT and its observables. We show that from minimal asser…
