Observation of nonlocal Josephson effect on double InAs nanowires
Communications Physics, 2022 Josephson junctions have applications in quantum circuits but producing and controlling the coupling between junctions is challenging. The authors characterize the electronic transport properties of two adjacent Josephson junctions, demonstrating short ...

Nonlocality-induced front interaction enhancement [PDF]
, 2010 We demonstrate that nonlocal coupling strongly influences the dynamics of fronts connecting two equivalent states. In two prototype models we observe a large amplification in the interaction strength between two opposite fronts increasing front ...

Local and Nonlocal Energy-Based Coupling Models
SIAM Journal on Mathematical Analysis, 2022 In this paper we study two different ways of coupling a local operator with a nonlocal one in such a way that the resulting equation is related to an energy functional. In the first strategy the coupling is given via source terms in the equation and in the second one a flux condition in the local part appears.

Coupling local and nonlocal evolution equations [PDF]
Calculus of Variations and Partial Differential Equations, 2020 We prove existence, uniqueness and several qualitative properties for evolution equations that combine local and nonlocal diffusion operators acting in different subdomains and coupled in such a way that the resulting evolution equation is the gradient flow of an energy functional.

Complex Ginzburg-Landau equation with nonlocal coupling [PDF]
Physical Review E, 2003 A Ginzburg-Landau-type equation with nonlocal coupling is derived systematically as a reduced form of a universal class of reaction-diffusion systems near the Hopf bifurcation point and in the presence of another small parameter. The reaction-diffusion systems to be reduced are such that the chemical components constituting local oscillators are ...

Toward a Nonlocal Theory of Gravitation [PDF]
, 2006 The nonlocal theory of accelerated systems is extended to linear gravitational waves as measured by accelerated observers in Minkowski spacetime. The implications of this approach are discussed.

Electromechanical Analysis of Flexoelectric Nanosensors Based on Nonlocal Elasticity Theory
Micromachines, 2020 Flexoelectric materials have played an increasingly vital role in nanoscale sensors, actuators, and energy harvesters due to their scaling effects. In this paper, the nonlocal effects on flexoelectric nanosensors are considered in order to investigate ...

Soliton solutions of the non-linear Schroedinger equation with nonlocal Coulomb and Yukawa-interactions [PDF]
, 2006 We study the non-linear Schroedinger equation in (1+1) dimensions in which the nonlinear term is taken in the form of a nonlocal interaction of the Coulomb or Yukawa-type.

Perturbative entanglement entropy in nonlocal theories [PDF]
, 2015 Entanglement entropy in the vacuum state of local field theories exhibits an area law. However, nonlocal theories at large N and strong coupling violate this area law. In these theories, the leading divergence in the entanglement entropy is extensive for

Tree-level scattering amplitudes in nonlocal field theories
Journal of High Energy Physics, 2021 We prove in two ways that, for a special class of nonlocal field theories consistent with linear and non-linear stability at the classical level, and with unitarity and super-renormalizability or finiteness at the quantum level, the n-point tree-level ...
