Detectability of Post-Quantum Correlations in Symmetry-Restricted Bell Scenarios
Marek Gazdzicki, Francesco Giacosa
Searches for post-quantum correlations depend on two distinct ingredients: how abundant such correlations are in the underlying correlation space and how efficiently the chosen rep…
From breakfast, lunch, and dinner to the Bell-inequality tetrahedron
Francesco Giacosa
A simple pedagogical discussion and visualization of certain Bell inequalities is presented with the help of a system involving two \textquotedblleft twins\textquotedblright, origi…
Symmetric Locality as a Tetrahedron: A Symmetry-Reduced Geometric Representation of the (3,3,2,2) Bell Scenario
Marek Gazdzicki, Francesco Giacosa, Pawel Piesowicz
We present a geometric characterisation of local models in the bipartite Bell scenario with three measurement settings per site and binary outcomes, i.e. the (3,3,2,2) case. Restri…
Scattering off unstable states
Francesco Giacosa, Vanamali Shastry
Unstable states that live long enough may appear as in(out)going particles in scattering experiments. Yet, the standard QFT approach strictly applies only to fully stable asymptoti…
Sill distribution: genesis and salient features
Francesco Giacosa, Vanamali Shastry
We present the so-called Sill distribution, both in the nonrelativistic and relativistic cases, as a natural and simple way to include the effect of threshold(s) on the energy line…
