The study of low-energy ion-neutral collisions is fundamental to understanding the behavior, control, and applications of cold, atomic, molecular, and ionic gaseous systems. At long range, universal charge-induced polarization effects dominate the ion-neutral elastic, inelastic, reactive, and charge-transfer cross sections. Neutral alkali targets are of particular importance due to their ubiquitous use in cold atomic molecular and optical experiments, as well as their uniquely large polarizability. As their collision energy is lowered, ion-alkali reaction cross sections approach millions of atomic units, many orders of magnitude larger than typical neutral-atom van der Waals cross sections at the same energy scale. However, cold ion-alkali reactions had remained relatively unexplored until the early 2000s, at which time advances in laboratory and computational techniques such as cold hybrid ion-neutral traps and many-body excited-state quantum chemistry modeling were developed. Since then, the cold ion-neutral collision regime has rapidly blossomed. Researchers continue to explore and demonstrate quantum-limited control over a wide variety of ion-neutral partners, investigating ion-neutral sympathetic heating and cooling, formation and cooling of cold molecular ions, probing of quantum gases, and quantum chemistry, simulations, and computations. This Special Issue aims to highlight recent experimental and theoretical work in the field of low-energy ion-neutral studies, review progress, and discuss the outlook for future developments. Authors are invited to submit original research papers for the Special Issue as well as short, tutorial reviews emphasizing new developments not included in previous reviews.

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 papers will be 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 100 words) can be sent to the Editorial Office for announcement on this website.
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 quarterly 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 1400 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.
