Computational Study of Shocked V-Shaped N₂/SF₆ Interface across Varying Mach Numbers

Axioms
The Mach number effect on the Richtmyer–Meshkov instability (RMI) evolution of the shocked V-shaped N2/SF6 interface is numerically studied in this research. Four distinct Mach numbers are taken into consideration for this purpose: Ms=1.12,1.22,1.42, and

Multi‐Channel Quantum Dot Single‐Photon Sources on a Fiber‐Integrated Platform

Advanced Optical Materials, EarlyView.
A breakthrough in achieving a multiple, tunable array of quantum photonic devices is presented. By combining an optimal nanophotonic cavity, individual device transfer process, and integrated electrodes on a V‐groove fiber, the all‐fiber integrated system exhibits capabilities of low‐temperature cooling, efficient single‐photon transmission, selective ...

Complex Structured Light Generation Using Printed Liquid Crystal Droplets

Advanced Optical Materials, EarlyView.
Inkjet‐printed liquid crystal droplets generate structured light beams with spatially varying polarization and phase. These include full Poincaré beam, vortex beam carrying orbital angular momentum, and beam with polarization singularities, offering a simple approach for compact structured light generation in optical manipulation, imaging, and ...

Aerodynamic Parameters Analysis of Transonic Flow Past Unswept and Swept Wings [PDF]

Engineering and Technology Journal, 2011
The transonic flow past unswept and swept wings has been studied. For this purpose the transonic potential flow equation is solved for inviscid compressible flow. The shock waves are replaced by discontinuities across which the entropy is conserved.

Electron Pre-acceleration at Nonrelativistic High-Mach-number Perpendicular Shocks [PDF]

, 2017
We perform particle-in-cell simulations of perpendicular nonrelativistic collisionless shocks to study electron heating and pre-acceleration for parameters that permit the extrapolation to the conditions at young supernova remnants.

Generalized Heterodyne Interferometry in Kerr Materials

Advanced Photonics Research, EarlyView.
Interferometry, combined with heterodyne detection, enables simultaneous measurement of light amplitude and phase. This work applies these methods to study nonlinear phase shifts from the optical Kerr effect during laser pulse propagation. Results show the nonlinear index is straightforward to retrieve at low phases, but at higher powers, pulse shape ...
