Zeitschrift für Naturforschung A, 2001 Abstract It is shown that all quantum “contradictions” disappear if one drops the assumption of unique initial conditions for a hidden variable theory for individual quantum processes. Our proposal corresponds with a deterministic world evolution such that local physical conditions are nonreproducible, in agreement with empirical ...

NONLOCAL EFFECTS IN QUANTUM GRAVITY [PDF]
Modern Physics Letters A, 1998 Recently,2 a new quantum gravity theory was presented in which the quantum effects were represented by the conformal degree of freedom of the space–time metric. In this letter we show that in the framework of this theory, quantum gravity is nonlocal.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

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.

Maximally nonlocal Clauser-Horne-Shimony-Holt scenarios
Scientific Reports, 2018 The key feature in correlations established by multi-party quantum entangled states is nonlocality. A quantity to measure the average nonlocality, distinguishing it from shared randomness and in a direct relation with no-signaling stochastic processes ...

On the Activation of Quantum Nonlocality
Universitas Scientiarum, 2016 We report on some quantum properties of physical systems, namely, entanglement, nonlocality, k-copy nonlocality (superactivation of nonlocality), hidden nonlocality (activation of nonlocality through local filtering) and the activation of nonlocality ...

In Praise of Quantum Uncertainty
Entropy, 2020 Quantum uncertainty has a tremendous explanatory power. Coherent superposition, quantum equations of motion, entanglement, nonlocal correlations, dynamical nonlocality, contextuality, discord, counterfactual protocols, weak measurements, quantization ...

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)].

Advanced Optical Materials, EarlyView.A comparative study of the optical and polaritonic properties of excitons in hBN‐encapsulated monolayer TMDs close to the homogeneous linewidth is presented. Reflection spectroscopy with transmission‐line modeling enables extraction of the complex permittivities and demonstrate their ability to host surface‐exciton‐polaritons.

Hierarchical relationship of nonlocal correlations in Schwarzschild-de Sitter spacetime
European Physical Journal C: Particles and FieldsWe investigate the hierarchy of nonlocal correlations for Dirac fields in the Schwarzschild de Sitter (SdS) spacetime. We find that the hierarchical relationship between the nonlocal advantage of quantum coherence (NAQC) and Bell nonlocality remains in ...
