Nonlocal pagerank [PDF]

open access: yesESAIM: Mathematical Modelling and Numerical Analysis, 2021
In this work we introduce and study a nonlocal version of the PageRank. In our approach, the random walker explores the graph using longer excursions than just moving between neighboring nodes. As a result, the corresponding ranking of the nodes, which takes into account along-range interactionbetween them, does not exhibit concentration phenomena ...

Nonlocal Cosmology [PDF]

open access: yesPhysical Review Letters, 2007
We explore nonlocally modified models of gravity, inspired by quantum loop corrections, as a mechanism for explaining current cosmic acceleration. These theories enjoy two major advantages: they allow a delayed response to cosmic events, here the transition from radiation to matter dominance, and they avoid the usual level of fine tuning; instead ...

Quasi-nonlocal Coupling of Nonlocal Diffusions [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2017
We developed a new self-adjoint, consistent, and stable coupling strategy for nonlocal diffusion models, inspired by the quasinonlocal atomistic-to-continuum method for crystalline solids. The proposed coupling model is coercive with respect to the energy norms induced by the nonlocal diffusion kernels as well as the $L^2$ norm, and it satisfies the ...

Operational Significance of the Quantum Resource Theory of Buscemi Nonlocality

open access: yesPRX Quantum, 2021
Although entanglement is necessary for observing nonlocality in a Bell experiment, there are entangled states that can never be used to demonstrate nonlocal correlations. In a seminal paper Buscemi [Phys. Rev. Lett.

Nonlocality is Transitive [PDF]

open access: yesPhysical Review Letters, 2011
We show a transitivity property of nonlocal correlations: There exist tripartite nonsignaling correlations of which the bipartite marginals between A and B as well as B and C are nonlocal and any tripartite nonsignaling system between A, B, and C consistent with them must be such that the bipartite marginal between A and C is also nonlocal.

Speeding up the spread of quantum information in chaotic systems

open access: yesJournal of High Energy Physics, 2021
We explore the effect of introducing mild nonlocality into otherwise local, chaotic quantum systems, on the rate of information spreading and associated rates of entanglement generation and operator growth.

Quantum Nonlocality for a Mixed Entangled Coherent State [PDF]

open access: yes, 2001
Quantum nonlocality is tested for an entangled coherent state, interacting with a dissipative environment. A pure entangled coherent state violates Bell's inequality regardless of its coherent amplitude.

Nonlocality Without Nonlocality [PDF]

open access: yesFoundations of Physics, 2009
15 pages, 9 figures (some color). Changes in version 2 include (1) a correction to the abstract: Bell's theorem is now said to demonstrate the impossibility of a local hidden variable theory, (2) the "non-spacelike" initial value problem is now the "mixed" initial value problem, (3)the figures should reproduce more clearly.
