Theory of Photoluminescence Spectral Line Shapes of Semiconductor Nanocrystals. [PDF]
Journal of Physical Chemistry Letters, 2022 Single-molecule photoluminescence (PL) spectroscopy of semiconductor nanocrystals (NCs) reveals the nature of exciton-phonon interactions in NCs. Understanding the homogeneous spectral line shapes and their temperature dependence remains an open problem.

The APOGEE Data Release 16 Spectral Line List [PDF]
Astronomical Journal, 2021 The updated H-band spectral-line list (from λ15000–17000) adopted by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) for the SDSS-IV Data Release 16 (DR16) is presented in this work. The APOGEE line list is a combination of atomic and

Discrete time model of self-oscillations with spectral line widening
Физика волновых процессов и радиотехнические системы, 2022 An algorithm for generating quasi-harmonic self-oscillations with a uniformly widened spectral line is presented. The algorithm is based on the equation of motion of the Thomson-type DT-oscillator, which introduced a random effect in the form of band ...

Introduction to spectral line shape theory
Journal of Physics B: Atomic, Molecular and Optical Physics, 2022 Spectral line-shape models are an important part of understanding high-energy-density (HED) plasmas. Models are needed for calculating opacity of materials and can serve as diagnostics for astrophysical and laboratory plasmas.

Phase-space Spectral Line Deconfusion in Intensity Mapping [PDF]
Astrophysical Journal, 2020 Line intensity mapping (LIM) is a promising tool to efficiently probe the three-dimensional large-scale structure by mapping the aggregate emission of a spectral line from all sources that trace the matter density field.

All-Order Full-Coulomb Quantum Spectral Line-Shape Calculations.
Physical Review Letters, 2021 Understanding how atoms interact with hot dense matter is essential for astrophysical and laboratory plasmas. Interactions in high-density plasmas broaden spectral lines, providing a rare window into interactions that govern, for example, radiation ...
