On the interpretation and significance of the fluctuation-dissipation theorem in infrared spectroscopy
Sven Nordebo
In this paper we revisit the classical fluctuation-dissipation theorem with derivations and interpretations based on quantum electrodynamics (QED). As a starting point we take the…
A modified projection approach to line mixing

This paper presents a simple approach to combine the high-resolution narrowband features of some desired isolated line models together with the far wing behavior of the projection…
Uniform error bounds for fast calculation of approximate Voigt profiles
Sven Nordebo
The broadband line-by-line analysis of radiative transfer in the atmosphere is extremely demanding with regard to computational resources. As a remedy, we present here the calculat…
On the optical theorem and optimal extinction, scattering and absorption in lossy media

Optical theorems and physical bounds on absorption in lossy media
Yevhen Ivanenko, Mats Gustafsson, Sven Nordebo
Two different versions of an optical theorem for a scattering body embedded inside a lossy background medium are derived in this paper. The corresponding fundamental upper bounds o…
Physical meaning of the dipole radiation resistance in lossless and lossy media
