Quantum-like states from classical systems [0.0]
This work studies how a suitably-designed classical system generates with a quantum-like (QL) state space mediated by a graph.<n>The question of whether and, if so, how, entanglement can be exhibited by these QL systems is discussed critically and contrasted to the concept of classical entanglement' in optics.

We consider spurious features that are uncorrelated with the learning task. We provide a precise characterization of how they are memorized via two separate terms. We prove that the memorization of spurious features weakens as the generalization capability increases.

Localisation in quasiperiodic chains: a theory based on convergence of local propagators [68.8204255655161]
We present a theory of localisation in quasiperiodic chains with nearest-neighbour hoppings, based on the convergence of local propagators. Analysing the convergence of these continued fractions, localisation or its absence can be determined, yielding in turn the critical points and mobility edges. Results are exemplified by analysing the theory for three quasiperiodic models covering a range of behaviour.

Extensions of Hardy-type true-implies-false gadgets to classically obtain indistinguishability [0.0]
Hardy-type arguments can be uniformly presented and extended as collections of intertwined contexts and their observables. They serve as graph-theoretic "gadgets" that enforce correlations on the respective preselected and postselected observable terminal points.

Emergence of classical behavior in the early universe [68.8204255655161]
Three notions are often assumed to be essentially equivalent, representing different facets of the same phenomenon. We analyze them in general Friedmann-Lemaitre- Robertson-Walker space-times through the lens of geometric structures on the classical phase space. The analysis shows that: (i) inflation does not play an essential role; classical behavior can emerge much more generally; (ii) the three notions are conceptually distinct; classicality can emerge in one sense but not in another.
