Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes
Laser &Photonics Reviews, EarlyView.This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip

Causality and nonlocality as axioms for quantum mechanics [PDF]
, 1997 Quantum mechanics permits nonlocality-both nonlocal correlations and nonlocal equations of motion-while respecting relativistic causality. Is quantum mechanics the unique theory that reconciles nonlocality and causality?

Laser &Photonics Reviews, EarlyView.An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

Nonlocal active sound control for composite regions
Mathematical Methods in the Applied Sciences, EarlyView.In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.

d-outcome measurement for a nonlocality test [PDF]
, 2004 For the purpose of a nonlocality test, we propose a general correlation observable of two parties by utilizing local d- outcome measurements with SU(d) transformations and classical communications.

Mathematical Methods in the Applied Sciences, EarlyView.The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

Finality and the Demystification of Entanglement [PDF]
Journal of Interdisciplinary SciencesThis paper presents the thesis that the concept of finite quantized (not infinitely subdividable) spacetime is the missing element of reality, the hidden variable that can provide an explanation for so-called nonlocality that is simple and plausible ...

Beyond Space and Time: Quantum Superposition as a Real-Mental State About Choices
Condensed MatterThis contribution aims to honour Guido Barbiellini’s profound interest in the interpretation and impact of quantum mechanics by examining the implications of the so-called before–before Experiment on quantum entanglement.

Aspects of nonlocality and quantum thermodynamics [PDF]
, 2011 This thesis is a tale of two stories. The first half of this thesis is dedicated to the study of nonlocality. We know that nature is inherently nonlocal, however, the nonlocal correlations allowed by quantum mechanics are limited; we could conceivably ...
