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…

Taming non-analyticities of QFT observables
Thomas W. Grimm, Giovanni Ravazzini, Mick van Vliet
Many observables in quantum field theories are involved non-analytic functions of the parameters of the theory. However, it is expected that they are not arbitrarily wild, but rath…

Structure and Complexity of Cosmological Correlators
Thomas W. Grimm, Arno Hoefnagels, Mick van Vliet
Cosmological correlators capture the spatial fluctuations imprinted during the earliest episodes of the universe. While they are generally very non-trivial functions of the kinemat…
