Measurement-Induced Nonlocality
Physical Review Letters, 2011We interpret the maximum global effect caused by locally invariant measurements as measurement-induced nonlocality, which is in some sense dual to the geometric measure of quantum discord [Dakic, Vedral, and Brukner, Phys. Rev. Lett. 105, 190502 (2010)].

Multiresonant Nonlocal Metasurfaces
Nano Letters, 2023Optical metasurfaces supporting localized resonances have become a versatile platform for shaping the wavefront of light, but their low quality (Q-) factor modes inevitably modify the wavefront over extended momentum and frequency space, resulting in limited spectral and angular control.

Physical Review Letters, 2005
We show how an effective nonlocality in imaging can lead to the sampling of a spatial region which is not significantly illuminated by an imaging probe. The nonlocality is embodied in the effective nonlocal potential describing inelastic scattering which occurs when coupled channel Schrödinger equations are reduced to a single integro-differential ...

IEEE Transactions on Image Processing, 2014
In this paper, we introduce a new image editing tool based on the spectrum of a global filter computed from image affinities. Recently, it has been shown that the global filter derived from a fully connected graph representing the image can be approximated using the Nyström extension. This filter is computed by approximating the leading eigenvectors of

Physical Review D, 1991
We describe a method for introducing gauge fields into nonlocal Lagrangians, and for deriving the resulting Feynman rules. The method is applied in detail to the nonlocal chiral quark model. In particular we describe how to calculate coupling constants of the effective chiral Lagrangian that results when the quarks are integrated out of the theory.

Physical Review B, 1992
I derive accurate nonlocal relations between the conductivity and diffusion (the Einstein formula), between the current density and local voltage, and between the local voltage and total current. These relations provide a complete description of charge transfer. Their nonlocality is shown to arise only through the density-density correlation function.

Summary: By constructing a series of mixture, which is inseparable but satisfies the Mermin-Klyshko inequality, for the \(N\)-qubit system, we prove that ``violation of the Mermin-Klyshko inequality'' is not equivalent to ``the state is inseparable''.

Nonlocal Minimal Surfaces and Nonlocal Curvature
2019Recall that if a set E has minimal local perimeter in a bounded set Ω, then it has zero mean curvature at each point of ∂E ∩ Ω (see [51]), and the equation that says that the curvature is equal to zero is the Euler–Lagrange equation associated to the minimization of the perimeter of a set.

Anomalous viscoelastic, diffusion, and heat-transfer phenomena observed in spatially inhomogeneous simple and complex fluids are analyzed in this paper in the setting of weakly nonlocal hydrodynamics. Governing equations of this generalized hydrodynamics involve higher-order derivatives with respect to the position coordinate.
