Numerical evaluation of spin foam amplitudes beyond simplices
Courtney Allen, Florian Girelli, Sebastian Steinhaus
We present the first numerical calculation of the 4D Euclidean spin foam vertex amplitude for vertices with hypercubic combinatorics. Concretely, we compute the amplitude for coher…

Changing quantum reference frames
Matthew C. Palmer, Florian Girelli, Stephen D. Bartlett
We consider the process of changing reference frames in the case where the reference frames are quantum systems. We find that, as part of this process, decoherence is necessarily i…
