Abstract Brout–Englert–Higgs physics is one of the most central and successful parts of the
standard model. It is also part of a multitude of beyond-the-standard-model scenarios. The …

We study real-time meson-meson scattering processes in (1+ 1)-dimensional QED by
means of tensor networks. We prepare initial meson wave packets with given momentum …

Despite the plausible necessity of topological protection for realizing scalable quantum
computers, the conceptual underpinnings of topological quantum logic gates had arguably …

A bstract In the tensorial group field theory (TGFT) approach to quantum gravity, the basic
quanta of the theory correspond to discrete building blocks of geometry. It is expected that …

The functional renormalization group (FRG) approach is a powerful tool for studies of a large
variety of systems, ranging from statistical physics over the theory of the strong interaction to …

A bstract In order to calculate QED corrections to hadronic physical quantities by means of
lattice simulations, a coherent description of electrically-charged states in finite volume is …

While fractional quantum Hall systems provide the best experimental evidence yet of
(abelian) anyons plausibly necessary for future fault-tolerant quantum computation, like all …

It has sometimes been suggested that quantum phenomena exhibit a characteristic holism
or nonseparability, and that this distinguishes quantum from classical physics. One puzzling …

We demonstrate that the reformulation of renormalization group (RG) flow equations as
nonlinear heat equations has severe implications on the understanding of RG flows in …

Tensor network methods are a class of numerical tools and algorithms to study many-body
quantum systems in and out of equilibrium, based on tailored variational wave functions …
