SUMMARY AND CONCLUSIONS The (nonlocal) Bonn-B potential predicts 8.0 MeV binding energy for the triton (in a charge-dependent 34-channel Faddeev calculation) which is about 0.4 MeV more than the predictions by local NN potentials. We pin down origin and size of the nonlocality in the Bonn potential, in analytic and numeric form. The nonlocality is due to the use of the correct off-shell Feynman...

Spontaneous emission (SE) rate and the fluorescence efficiency of a bare fluorescing nanoparticle and the nanoparticle with a silver nanoshell are analyzed rigorously by using a classical electromagnetic approach with the consideration of the nonlocal effect of the silver nano-shell. The dependences of the SE rate and the fluorescence efficiency on the core-shell structure are carefully studied...

In this paper, we study some qualitative properties for solutions to an evolution problem that combines local and nonlocal diffusion operators acting in two different subdomains. The coupling takes...

We develop a shell model (SM) for potassium dihydrogen phosphate (KDP) which is fitted to ab initio (AI) results that include nonlocal van der Waals corrections. The SM comprehensively tested by comparing of structural, vibrational and ferroelectric properties with AI experimental data. relaxed structural parameters are in very good agreement the available $\Gamma$-point phonons total phonon de...

We compute the tree level 4-particle bosonic scattering amplitudes in D511 supergravity. By construction, they are part of a linearized supersymmetry, coordinate, and 3-form gauge invariant. While this on-shell invariant is nonlocal, suitable SUSY-preserving differentiations turn it into a local one with correct dimension to provide a natural lowest ~two-loop! order counterterm candidate. Its e...

In this paper, a novel nonlocal anisotropic elastic shell model is developed to investigate the nonlinear vibrations of double-walled carbon nanotubes (DWCNTs) in framework Sanders–Koiter theory. Van der Waals interaction forces between two concentric single-walled (SWCNTs) composing DWCNT are modelled via Lennard-Jones potential and He’s formulation. linear vibration analysis, displacement fie...

in this study, thermo-mechanical nonlinear vibration of a polyethylene (pe) cylindrical shell embedded in an elastic foundation was investigated. the shell is reinforced by armchair carbon nanotubes (cnts) where characteristics of the equivalent composite being determined using mori-tanaka model. the elastic medium is simulated using the spring constant of the winkler-type,  . employing nonline...

We study a weakly local, but nonlocal model in spacetime dimension d ≥ 2 which satisfies the remaining Wightman axioms. We prove that this model is (quantitatively) maximally nonlocal; nevertheless, it has string–localized observables of the sort which enable two–body scattering theory to be defined. In two spacetime dimensions, it even has a covariant and local subnet of observables localized ...
