Pseudomagnetic fields for classical waves in two‐dimensional artificial lattices: Mechanisms and applications

open access: yesInfoScience, EarlyView.
Pseudomagnetic fields make light and sound emulate charged particles in magnetic fields, enabling magnetic‐free signal processing. This Review summarizes their origins, three implementations in two‐dimensional artificial lattices, and applications in energy localization and robust transport, guiding the design of topological integrated devices ...

Regulating electronic coupling and molecular vibration to facilitate exciton transfer of fused ring electron acceptors enables 20.66% efficiency of organic solar cells

open access: yesInfoMat, EarlyView.
Introducing L8‐F efficiently reinforces electronic coupling and suppresses molecular vibration for L8‐BO:L8‐F to afford ultra‐fast exciton transfer rate and thus prolonged exciton diffusion length. Therefore, D18:L8‐BO:L8‐F based organic solar cells (OSCs) acquire more efficient exciton dissociation and weaker charge carrier recombination to achieve an

Detection of Acoustic Phonons in Carbon by Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
Acoustic phonons in graphite and diamond are detected by Raman spectroscopy through disorder‐induced relaxation of selection rules. Comparison with calculated phonon densities of states enables assignment of the observed Raman features to acoustic phonon branches.

A Complex‐Frequency Framework for Kerker Unidirectionality in Photonic Resonators

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT Electromagnetic scattering exhibits various anomalous behaviors, such as forward or backward scattering effects known as the Kerker conditions. These anomalies appear in non‐Hermitian photonic resonators and are mathematically described by operators with complex eigenfrequencies.

3-rd Spring School on Acousto-Optics and Applications Gdańsk–Wieżyca, May 29-31, 1986 // Istituto di Acustica ,,O. M. Corbino’’, 50th anniversary celebration, Rome, Italy, 28-30 april 1987

open access: yesArchives of Acoustics
The 3-rd School on Acousto-optics and Applications like the two previous ones (in 1980 – Arch. Acoust. 6 (1981) 85-86 and in 1983 – Arch. Acoust. 9 (1984) 382-382) took place at Wieżyca near Gdańsk in the recreation centre of the Gdynia Shipyard.

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.
