Inelastic electron and light scattering from the elementary electronic excitations in quantum wells: Zero magnetic field

open access: yesAIP Advances, 2012
The most fundamental approach to an understanding of electronic, optical, and transport phenomena which the condensed matter physics (of conventional as well as nonconventional systems) offers is generally founded on two experiments: the inelastic ...

Mean-Field Description of Cooperative Scattering by Atomic Clouds

open access: yesAtoms, 2023
We present analytic expressions for the scattering of light by an extended atomic cloud. We obtain the solution for the mean-field excitation of different atomic spherical distributions driven by a uniform laser, including the initial build up, the ...

Classical and Quantum Collective Recoil Lasing: A Tutorial

open access: yesAtoms, 2021
Collective atomic recoil lasing (CARL) is a process during which an ensemble of cold atoms, driven by a far-detuned laser beam, spontaneously organize themselves in periodic structures on the scale of the optical wavelength.

Sparse interferometry for measuring multiphoton collective phase

open access: yesPhysical Review Research, 2022
A multiphoton collective phase is a multiphoton-scattering feature that cannot be reduced to a sequence of two-photon scattering events, and the three-photon “triad phase” is the smallest nontrivial example.

Multimode Collective Atomic Recoil Lasing in Free Space

open access: yesAtoms, 2020
Cold atomic clouds in collective atomic recoil lasing are usually confined by an optical cavity, which forces the light-scattering to befall in the mode fixed by the resonator.

Azimuthal correlations in photoproduction and deep inelastic ep scattering at HERA

open access: yesJournal of High Energy Physics, 2021
Collective behaviour of final-state hadrons, and multiparton interactions are studied in high-multiplicity ep scattering at a centre-of-mass energy s $$ \sqrt{s} $$ = 318 GeV with the ZEUS detector at HERA.

Phonon Thermal Hall Conductivity from Scattering with Collective Fluctuations

open access: yesPhysical Review X, 2022
Because electrons and ions form a coupled system, it is a priori clear that the dynamics of the lattice should reflect symmetry breaking within the electronic degrees of freedom. Recently, this has been clearly evidenced for the case of time-reversal and

Particle-in-cell simulation feasibility test for analysis of non-collective Thomson scattering as a diagnostic method in ITER

open access: yesNuclear Engineering and Technology, 2020
The feasibility of the particle-in-cell (PIC) method is assessed to simulate the non-collective phenomena like non-collective Thomson scattering (TS). The non-collective TS in the laser-plasma interaction, which is related to the single-particle behavior,

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.

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 ...
