Current Studies and Applications of Radiative and Collisional Processes in Atoms

Dear Colleagues,

The determination of fundamental parameters related to radiative and collisional processes in atoms has always played a major role in the development of other research fields, such as astrophysics, plasma physics, laser physics, photonics, material science, etc. In recent years, the spectacular improvement in the technical means employed in these disciplines has led to growing demand for a very large amount of reliable atomic data to interpret observations. At the same time, the theoretical and experimental methods employed for studying radiative and collisional processes in atomic systems have continuously improved, particularly thanks to the use of high-performance computational resources, on the one hand, and the development of very precise instrumental techniques on the other hand. Furthermore, the advent of artificial intelligence opens interesting prospects for its use in the analysis of complex atomic spectra.

This Special Issue aims to collect high-quality contributions presented at the 1st and 2nd International Online Conferences on Atoms (IOCAT 2026 and IOCAT 2027), as well as related original research papers in the broad field of atomic physics. Topics of interest include atomic structure and spectroscopy, radiative and collisional processes, atomic data for astrophysical and laboratory plasmas, strong-field and laser–matter interactions, cold atoms and quantum technologies, computational methods and artificial intelligence applications in atomic physics, and fundamental tests and precision measurements using atoms. Both theoretical and experimental studies are welcome, together with review articles addressing recent advances and emerging directions in the field.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atoms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
