Special Issue Information
Dear Colleagues,
In this Special Issue, we offer an overview of the current theoretical methods and experimental techniques for studying photoionization, along with its applications in diverse fields such as astrophysics and radiobiology.
Photoionization provides a fundamental probe of the electronic structure and electron dynamics in atoms and molecules, opening the way to understanding time at its most elementary scale.
In 2001, a milestone in laser science was achieved with the generation of pulses lasting only hundreds of attoseconds (10−18 s), giving rise to the field of attophysics. Pierre Agostini, Ferenc Krausz, and Anne L'Huillier were awarded the 2023 Nobel Prize in Physics for their pioneering work in this field, establishing attophysics as a new frontier in science.
Photoionization lies at the heart of attophysics. Time delays in photoemission encode crucial information about electron correlation and many-body interactions. These delays challenge the notion of photoionization as an instantaneous process. In molecules, attosecond techniques open the door to tracking charge migration, which can determine the breaking of chemical bonds and, ultimately, the outcome of a reaction.
The potential applications of the above-mentioned processes are far-reaching. Understanding ultrafast electron emission may provide insights into radiation damage mechanisms in biological matter and improve our knowledge of light–matter interactions in solids.
This Special Issue welcomes studies on photoionization, ultrafast processes, and attosecond pulses, including their interactions with condensed matter. We aim to advance the understanding of the quantum world through innovative and cutting-edge studies of photoionization reactions.
Research areas may include (but are not limited to) the following:
- Photoionization cross-sections of atoms and molecules;
- Multi-photon reactions;
- Non-dipole effects;
- ATI processes;
- Photoionization of atoms and molecules by attopulses assisted by lasers;
- Attochronoscopy (delay times).

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-blind 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.
