Special Issue Information

Dear Colleagues,

As Editor-in-Chief of Symmetry, I am pleased to announce this Special Issue, entitled “Symmetry: Feature Papers 2026”. In recent years, we have collaborated with outstanding scholars and scientific groups and have published several important high-level studies that have already received numerous citations according to data from Web of Science. Our aim is to present new insights into scientific developments and cutting-edge technologies related to the field of symmetry that will make significant contributions to the research community. Accordingly, we will continue the “Symmetry: Feature Papers” Special Issue series in 2026.

You are welcome to submit short proposals for Feature Paper submissions to our Editorial Office (symmetry@mdpi.com) prior to full manuscript submission. After evaluation of the proposals, selected papers may be considered for publication free of charge.

All submissions will first be evaluated by our Editors. Please note that selected full papers will still be subject to thorough and rigorous peer review.

Prof. Dr. Sergei D. Odintsov
Guest Editor

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. Symmetry 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 2400 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.

We study the SU(N) symmetric model, which describes interaction of gravity with three field multiplets: first, the multiplet of pseudoscalar fields, which is at present associated with the multi-component cosmic dark matter; second, the multiplet of vector fields, which represents the so-called color aether, now known as dynamic aether; third, the multiplet of Yang–Mills fields, which provides the SU(N) invariance of the model as a whole. It was previously known that the decay of the color aether in the early Universe could have given rise to emergence of an axionic singlet according to the Peccei–Quinn mechanism; we proposed an extended scheme, according to which the color aether activates an additional internal tool for generating not only a simple axionic singlet, but an entire SU(N) symmetric multiplet of pseudoscalar fields. Late-time evolution of the considered field configuration is analyzed in the framework of the Bianchi-I cosmological model, and a hypothesis is proposed that the aforementioned pseudoscalar multiplet can be associated with the multi-component cosmic dark matter.
