Special Issue Information
Dear Colleagues,
Much like in particle physics, symmetries play a fundamental role in cosmology and have proved to be an invaluable tool in theoretical research, such as in the effective field theories of inflation, dark energy, and the large-scale structure; consistency relations and soft theorems of correlation functions; and the cosmological bootstrap program. On the other hand, asymmetries (or the breaking of symmetries) are likewise fundamentally important, potentially serving to gain insight into a wealth of new physics, for instance, through the mechanisms of baryogenesis, leptogenesis, or parity violation in cosmological observables, particularly gravitational waves.
This Special Issue aims to explore the impact of symmetry and asymmetry as guiding principles in cosmological research, including fundamental aspects of early universe physics; model building as applied to inflation, dark matter, and dark energy; and phenomenological, observational, and data analysis-oriented work aiming to measure and constrain these. Through the inclusion of this broad set of research approaches, the Special Issue aims to mirror the unprecedented advances in theoretical and experimental cosmology that the field has witnessed in recent years.
We welcome submissions from scientists with interest in the following areas:
- Cosmic inflation;
- Early-universe cosmology;
- Primordial non-Gaussianity;
- Primordial gravitational waves;
- Cosmological bootstrap;
- Effective field theories in cosmology;
- Cosmological correlators;
- Cosmological collider physics;
- Topological defects and cosmic strings;
- Modified gravity;
- Axion cosmology;
- Baryogenesis and leptogenesis;
- Parity violation in gravity and cosmology;
- Neutrino cosmology;
- Large-scale structure of the universe;
- Models of dark matter and dark energy;
- Cosmological tensions.

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 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. 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.
