Abstract:
We illustrate a non-perturbative technique that allows the standard Friedmann-Lemaitre-Robertson-Walker (FLRW) observer to evaluate a measurable, scale-dependent distance functional between her idealized FLRW past light cone and the actual physical past light cone. This distance functional quantifies the FLRW symmetry-breaking in regions of spacetime where structure formation...

Abstract:
We analyse how the interplay between entanglement and quantum magic
constrains the structure of fundamental interactions, We show that the
entanglement generated by the scattering of gluons and gravitons is
maximal if the couplings preserve gauge invariance and diffeomorfism
invariance. Under the same conditions quantum magic, i.e. the
non-Clifford component that enables...

23. The Geometric Phase and the Spin-Statistics Theorem

Abstract:
The spin-statistics theorem has a long history and has been proved under a variety of assumptions. However, the consensus is that we do not yet understand the spin-statistics connection in its most intuitive and elementary form. In this work, we try to fill this gap by giving an intuitive, topological proof based on the idea that the histories of spinning elementary particles can...
