TL;DR: In this article, a review on recent developments and next perspectives in this scope, with particular regard to the use of QCLs in fundamental physics spectroscopic searches is given.

TL;DR: In this article, an experiment based on a molecular gas was proposed for a search in the axion mass range between 1.4 and 1.9 meV, where a 16O2 sample was brought to the temperature of 280 mK via buffer-gas cooling and then subjected to an external magnetic field.

TL;DR: A detection scheme to search for QCD axion dark matter, that is based on a direct interaction between axions and electrons explicitly predicted by DFSZ axion models, is presented, and the results rule out excitation of the upper Zeeman component of the ground state by laser-related heating effects.

TL;DR: In this paper, a detection scheme was proposed to search for QCD axion dark matter, which is based on direct interaction between axions and electrons explicitly predicted by DFSZ axion models.

TL;DR: In this paper, the authors present an experiment that aims to constrain, over a few-year timescale, the fractional temporal variation of the proton-to-electron mass ratio, β = mp/me, at a level of 10 −15 /yr by means of a spectroscopic frequency measurement on a beam of cold CF3H molecules.
