Direct and inverse spectral problems for Dirac systems with nonlocal potentials [PDF]
Opuscula Mathematica, 2019 The main purposes of this paper are to study the direct and inverse spectral problems of the one-dimensional Dirac operators with nonlocal potentials. Based on informations about the spectrum of the operator, we find the potential and recover the form of

Advanced Theory and Simulations, EarlyView.This work proposes a surface elasticity‐based nonlocal model for analyzing the vibrations of bi‐directionally graded tapered nanobeam. The results demonstrate that, in absence of surface effect, the increasing value of tapered parameter leads to stiffness‐hardening of the nanobeam. However, the consideration of surface effect changes this trend and the

Nonlocal boundary value problem in terms of flow for Sturm-Liouville operator in differential and difference statements [PDF]
E-Journal of Analysis and Applied Mathematics, 2019 Sturm-Liouville operator with second kind of nonlocal boundary value conditions is considered. For the classical solution, a priori estimate is established and unique existence is proved.

Multipartite fully-nonlocal quantum states
, 2010 We present a general method to characterize the quantum correlations obtained after local measurements on multipartite systems. Sufficient conditions for a quantum system to be fully-nonlocal according to a given partition, as well as being (genuinely ...

Nonlocal Conditions for Lower Semicontinuous Parabolic Inclusions [PDF]
Advances in Difference Equations, 2011 We discuss conditions for the existence of at least one solution of a discontinuous parabolic equation with lower semicontinuous right hand side and a nonlocal initial condition of integral type. Our technique is based on fixed point theorems for multivalued maps.

Solid State Defect Emitters With no Electrical Activity
Advanced Science, EarlyView.Point defects may introduce in‐gap states that alter electrical properties and lower the optical excitation threshold. It is thus widely assumed that solid‐state defect emitters alter the host conductivity. This study demonstrates, on a particular defect in 4H silicon carbide, that a yet unrecognized class of point defects exists that are optically ...

Meta‐Dispersive 3D Chromatic Confocal Measurement
Advanced Science, EarlyView.A dispersive metalens (DML) combined with the chromatic confocal method is achieved for high‐precision 3D measurement in this study. This approach enables both high axial and lateral resolutions in compact optics. The development offers a promising route toward precise, miniaturized depth sensing for future applications in microstructure inspection and

Nonlocal Gravity: Modified Poisson's Equation
, 2012 The recent nonlocal generalization of Einstein's theory of gravitation reduces in the Newtonian regime to a nonlocal and nonlinear modification of Poisson's equation of Newtonian gravity.

An elliptic singular system with nonlocal boundary conditions [PDF]
Nonlinear Analysis: Theory, Methods & Applications, 2012 Abstract We study the existence of solutions for the nonlinear second order elliptic system Δ u + g ( u ) = f ( x ) , where g ∈ C ( R N ∖ S , R N ) with S ⊂ R N bounded. Using topological degree methods, we prove an existence result under a geometric condition on g .

Lanthanide‐Doped Ga2O3: A Route to Bandgap Engineering for Ultraviolet Detection
Advanced Electronic Materials, EarlyView.Substitutional doping with lanthanide elements under charge balance conditions can effectively tune the bandgap of gallium oxide and has the potential to achieve a low background current in ultraviolet detection. Abstract The demand for next‐generation wide bandgap semiconductors is driven by applications such as solar‐blind ultraviolet detection and ...
