The authors study the correlations observed in quantum input Bell tests obtained from locally quantum no-signaling theories, which can reveal post-quantumness of bipartite “beyond-quantum” (i.e., more general than quantum) states that is undetectable with the standard classical input Bell tests. The study suggests the requirement of additional information principles to isolate the set of physical correlations.
Fractionality and symmetry in a square lattice

While a two-dimensional -symmetric lattice is always unstable, the author shows that the addition of fractionality can open a stability window.
