Nonlocality-controllable Kerr-nonlinearity in nonlocally nonlinear system with oscillatory responses
New Journal of Physics, 2020 We discuss the Kerr nonlinearities of the nonlocally nonlinear system with oscillatory responses by the variational approach. The self-focusing and self-defocusing states are found to dramatically depend on the degree of nonlocality.

Equivalence checking of quantum circuits by nonlocality
npj Quantum Information, 2022 Suppose two quantum circuit chips are located at different places, for which we do not have any prior knowledge, and cannot see the internal structures either.

Photon subtracted states and enhancement of nonlocality in the presence of noise
, 2005 We address nonlocality of continuous variable systems in the presence of dissipation and noise. Three nonlocality tests have been considered, based on the measurement of displaced-parity, field-quadrature and pseudospin-operator, respectively ...

Nonlocal Neural Networks, Nonlocal Diffusion and Nonlocal Modeling
, 2018 Nonlocal neural networks have been proposed and shown to be effective in several computer vision tasks, where the nonlocal operations can directly capture long-range dependencies in the feature space. In this paper, we study the nature of diffusion and damping effect of nonlocal networks by doing spectrum analysis on the weight matrices of the well ...

Discrete Radiative Modes in Plasmonic Nonlocal Flat Surfaces
PhotonicsThis paper provides a comprehensive study of the nonlocality-influenced radiative modes above the light line in the plasmonic nonlocal flat surface, including the plasmonic/dielectric interface, ultrathin plasmonic slab, and plasmonic/dielectric ...

Two Faced Janus of Quantum Nonlocality
Entropy, 2020 This paper is a new step towards understanding why “quantum nonlocality” is a misleading concept. Metaphorically speaking, “quantum nonlocality” is Janus faced. One face is an apparent nonlocality of the Lüders projection and

Nonlocal effects in temporal metamaterials
Nanophotonics, 2022 Nonlocality is a fundamental concept in photonics. For instance, nonlocal wave-matter interactions in spatially modulated metamaterials enable novel effects, such as giant electromagnetic chirality, artificial magnetism, and negative refraction. Here, we

Effects of nonlocality in time of interactions of an atom with its surroundings on the broadening of spectral lines of atoms [PDF]
, 2002 We investigate effects of nonlocality in time of the interaction of an atom with its surroundings on the spectral line broadening. We show that these effects can be very significant: In some cases nonlocality in time of this interaction can give rise to ...

Locality and Causality in Hidden Variables Models of Quantum Theory [PDF]
, 1997 Motivated by Popescu's example of hidden nonlocality, we elaborate on the conjecture that quantum states that are intuitively nonlocal, i.e., entangled, do not admit a local causal hidden variables model.
