Resonance broadening in high density gases

open access: yes, 1977
The resonance broadening of a transition between two excited states of a radiator in a high density gas is investigated. The important many body shielding contributions are included to all orders, and the two body correlations for the close collisions ...

Molecular structure and motion in zero field magnetic resonance [PDF]

open access: yes, 1989
Zero field magnetic resonance is well suited for the determination of molecular structure and the study of motion in disordered materials. Experiments performed in zero applied magnetic field avoid the anisotropic broadening in high field nuclear ...

One‐Component Carbon Dot Photoinitiator Enables High‐Fidelity Digital Light Processing 3D Printing With Improved Mechanical Resistance

open access: yesAdvanced Functional Materials, EarlyView.
Furfural carbon dots functionalized with acylphosphine oxide photosensitive groups (CD‐PO PI) demonstrate potential as one‐component photoinitiators for digital light processing (DLP) 3D printing. Compared to conventional diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide (TPO), CD‐PO PI offers improved printing resolution, resin toughness, and biological

Hadronic Resonances from STAR

open access: yesEPJ Web of Conferences, 2012
The results of resonance particle productions (ρ0, ω, K*, ϕ, Σ*, and Λ*) measured by the STAR collaboration at RHIC from various colliding systems and energies are presented. Measured mass, width, 〈pT〉, and yield of those resonances are reviewed.

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

open access: yesAdvanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.

Theory of resonance shifts of whispering gallery modes by arbitrary plasmonic nanoparticles

open access: yesNew Journal of Physics, 2013
Shifts of the resonance frequency of high Q whispering gallery modes (WGMs) in spherical dielectric microresonators by plasmonic nanoparticles can be greater than the WGM line width, such that the perturbation theory commonly used for describing ...

Bound-bound intraband resonance and inhomogeneous photoluminescence broadening in InAs/GaAs quantum dots

open access: yes, 2000
An inter/intra-band double-resonance technique that allows to make an unequivocal assignment of the resonant bound-bound intersublevel absorption in self-organized InAs/GaAs quantum dots is developed.
