Scattering phase delay and momentum transfer of light in disordered media

open access: yesPhysical Review Research, 2022
Disordered dielectric materials with short-range spatial correlations on length scales comparable to the wavelength of light display a rich variety of optical phenomena: photonic band gaps, structural coloring, strong scattering, and whiteness.

Scattering of Skyrmions [PDF]

open access: yes, 2015
In this paper, we present a detailed study of Skyrmion-Skyrmion scattering for two B=1 Skyrmions in the attractive channel where we observe two different scattering regimes. For large separation, the scattering can be approximated as interacting dipoles.

Strange hadron collectivity in pPb and PbPb collisions

open access: yesJournal of High Energy Physics, 2023
The collective behavior of K S 0 $$ {\textrm{K}}_{\textrm{S}}^0 $$ and Λ / Λ ¯ $$ \Lambda /\overline{\Lambda} $$ strange hadrons is studied by measuring the elliptic azimuthal anisotropy (v 2) using the scalar-product and multiparticle correlation ...

Observation of Light-Induced Dipole-Dipole Forces in Ultracold Atomic Gases

open access: yesPhysical Review X, 2022
Light-matter interaction is well understood on the single-atom level and routinely used to manipulate atomic gases. However, in denser ensembles, collective effects emerge that are caused by light-induced dipole-dipole interactions and multiple photon ...

Generation of spin-polarized hot electrons at topological insulators surfaces by scattering from collective charge excitations

open access: yesCommunications Physics, 2021
A key feature of topological insulators, such as Bi2Se3 is their protected electronic surface states where the direction of spin is locked to their momentum.

Random light scattering by collections of ellipsoids

open access: yesOptics Express, 2012
Theory of weak scattering of random optical fields from deterministic collections of particles with soft ellipsoidal scattering potentials of arbitrary shapes and orientations is developed. Far-field intensity distribution produced on scattering is shown to be influenced by source correlation properties as well as by a number, shapes and orientations ...

Collective scattering from quantum dots in a photonic crystal waveguide

open access: yes, 2022
We demonstrate scattering of laser light from two InAs quantum dots coupled to a photonic crystal waveguide, which is achieved by strain-tuning the optical transitions of the dots into mutual resonance.

Collective Mid-Infrared Vibrations in Surface-Enhanced Raman Scattering [PDF]

open access: yes, 2022
Surface-enhanced Raman scattering (SERS) is typically assumed to occur at individual molecules neglecting intermolecular vibrational coupling. Here, we show instead how collective vibrations from infrared (IR) coupled dipoles are seen in SERS from ...

Characteristics of magnon-phonon coupling in magnetic insulator based on the Boltzmann equation

open access: yesAIP Advances, 2023
The magnon, an elementary excitation of an orderly magnetic system, is currently receiving substantial attention due to its excellent spin transmission properties.

Collective Thomson scattering system for determination of ion properties in a high flux plasma beam [PDF]

open access: yes, 2016
A collective Thomson scattering system has been developed for measuring ion temperature, plasma velocity and impurity concentration in the high density magnetized Magnum-PSI plasma beam, allowing for measurements at low temperature (4 x 10 20m3,while ...
