Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride
Advanced Functional Materials, EarlyView.Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Off-Axis Gaussian Beams with Random Displacement in Atmospheric Turbulence [PDF]
Journal of Systemics, Cybernetics and Informatics, 2006 Our recent work in which we study the propagation of the general Hermite-sinusoidal-Gaussian laser beams in wireless broadband access telecommunication systems is elaborated in this paper to cover the special case of an off-axis Gaussian beam.

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook
Advanced Materials, EarlyView.Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Evidence for Itinerant Ferromagnetic Flat Bands Producing Large Transverse Responses
Advanced Materials, EarlyView.Itinerant ferromagnetic flat bands are demonstrated in GdCo5 with a high Curie temperature of 940K, a stacked honeycomb–kagome lattice, through angle‐resolved photoemission spectroscopy and magneto‐thermoelectric measurements. These topological flat bands generate large Berry curvaturte, producing gigantic anomalous Nernst effect with record‐high ...

Beam-Beam Simulations for Double-Gaussian Beams.
, 2005 Electron cooling together with intra-beam scattering results in a transverse distribution that can best be described by a sum of two gaussians, one for the high-density core and one for the tails of the distribution.

Far field intensity distributions due to spatial self phase modulation of a Gaussian beam by a thin nonlocal nonlinear media [PDF]
, 2010 In this work we present a simple model that can be used to calculate the far field intensity distributions when a Gaussian beam cross a thin sample of nonlinear media but the response can be ...
