Switchable Thermal Mid‐IR Conducting Polymer Antenna Arrays

Advanced Functional Materials, EarlyView.
This study presents switchable mid‐infrared plasmonic resonances in PEDOT antenna arrays. Their optical extinction peaks can be reversibly switched ‘OFF’ and ‘ON’ by tuning the polaronic charge carrier concentration via the polymer's redox state, offering modulation of optical responses in the thermal mid‐infrared range including around 10 µm ...

Sharing quantum nonlocality under Hawking effect of a Schwarzschild black hole

European Physical Journal C: Particles and Fields
Sharing nonlocality refers to whether the postmeasurement state in a Bell test can be reused to demonstrate nonlocality among multiple observers conducting sequential measurements.

d-Path Laplacians and Quantum Transport on Graphs

Mathematics, 2020
We generalize the Schrödinger equation on graphs to include long-range interactions (LRI) by means of the Mellin-transformed d-path Laplacian operators.

Exploring the Limits of Quantum Nonlocality with Entangled Photons

Physical Review X, 2015
Nonlocality is arguably among the most counterintuitive phenomena predicted by quantum theory. In recent years, the development of an abstract theory of nonlocality has brought a much deeper understanding of the subject, revealing a rich and complex ...

Quantum networks reveal quantum nonlocality

, 2010
The results of local measurements on some composite quantum systems cannot be reproduced classically. This impossibility, known as quantum nonlocality, represents a milestone in the foundations of quantum theory.

Three-particle entanglement versus three-particle nonlocality [PDF]

, 2002
The notions of three-particle entanglement and three-particle nonlocality are discussed in the light of Svetlichny's inequality [Phys. Rev. D 35, 3066 (1987)].

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

Advanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Bell's Nonlocality Can be Detected by the Violation of Einstein-Podolsky-Rosen Steering Inequality [PDF]

, 2016
Recently quantum nonlocality has been classified into three distinct types: quantum entanglement, Einstein-Podolsky-Rosen steering, and Bell's nonlocality. Among which, Bell's nonlocality is the strongest type.

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

Advanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Nonlocality III: General Nonlocality in Quantum Fields

, 2008
The waves of fermions display nonlocality in low energy limit of quantum fields. In this \QTR{it}{ab initio} paper we propose a complex-geometry model that reveals the affection of nonlocality on the interaction between material particles of spin-1/2. To
