Causal hierarchy of multipartite Bell nonlocality [PDF]
Quantum, 2017 As with entanglement, different forms of Bell nonlocality arise in the multipartite scenario. These can be defined in terms of relaxations of the causal assumptions in local hidden-variable theories.

Minimizers of nonlocal polyconvex energies in nonlocal hyperelasticity
Advances in Calculus of Variations, 2023 Abstract We develop a theory of existence of minimizers of energy functionals in vectorial problems based on a nonlocal gradient under Dirichlet boundary conditions. The model shares many features with the peridynamics model and is also applicable to nonlocal solid mechanics, especially nonlinear elasticity.

Einstein-Podolsky-Rosen Steering for Mixed Entangled Coherent States
Entropy, 2021 By using the Born Markovian master equation, we study the relationship among the Einstein–Podolsky–Rosen (EPR) steering, Bell nonlocality, and quantum entanglement of entangled coherent states (ECSs) under decoherence.

Nonlocality detection in photonic triangle networks [PDF]
, 2023 We implement triangle causal structures in photonics platforms and detect different forms of nonlocality. In particular, we focused on the Genuine Multipartite Nonlocality and on the nonlocality exhibited in a network without freedom of choice.No Full ...

Recycling qubits for the generation of Bell nonlocality between independent sequential observers [PDF]
, 2022 There is currently much interest in the recycling of entangled systems, for use in quantum information protocols by sequential observers. In this work, we study the sequential generation of Bell nonlocality via recycling one or both components of two ...

Operational Framework for Nonlocality [PDF]
Physical Review Letters, 2012 Due to the importance of entanglement for quantum information purposes, a framework has been developed for its characterization and quantification as a resource based on the following operational principle: entanglement among $N$ parties cannot be created by local operations and classical communication, even when $N-1$ parties collaborate.

Exposure of subtle multipartite quantum nonlocality
npj Quantum Information, 2021 The celebrated Einstein–Podolsky–Rosen quantum steering has a complex structure in the multipartite scenario. We show that a naively defined criterion for multipartite steering allows, like in Bell nonlocality, for a contradictory effect whereby local ...

Entropy, 2021 This note is a part of my effort to rid quantum mechanics (QM) nonlocality. Quantum nonlocality is a two faced Janus: one face is a genuine quantum mechanical nonlocality (defined by the Lüders’ projection postulate).

A NONLOCAL VECTOR CALCULUS, NONLOCAL VOLUME-CONSTRAINED PROBLEMS, AND NONLOCAL BALANCE LAWS [PDF]
Mathematical Models and Methods in Applied Sciences, 2013 A vector calculus for nonlocal operators is developed, including the definition of nonlocal divergence, gradient, and curl operators and the derivation of the corresponding adjoint operators. Nonlocal analogs of several theorems and identities of the vector calculus for differential operators are also presented.
