Special Issue Information
Dear Colleagues,
Symmetry principles play an important role concerning the laws of nature, where the regularities of these laws are independent of specific dynamics. The search for fundamental symmetries in nature is such a deep and broad question that it connects many different aspects of physics and can bring together physicists of various expertise. Both local and global symmetries play important roles in elementary particle physics and quantum gravity. In addition, applying symmetries in physics problems can often simplify these problems. Many of the known solutions of general relativity are derived by imposing symmetries. In addition, uniqueness theorems are formulated for many black hole solutions. The proof of these theorems is often based on the existence of an underlying Killing symmetry.
Symmetry plays such an important role in the physical aspects of the universe; much of the texture of the world is due to mechanisms of symmetry breaking. For example, global symmetry in classical general relativity could be broken by the no-hair theorem of black holes. It has also been suspected that the consistency of quantum gravity places constraints on what kinds of symmetries can exist in nature. Thus, delving into symmetries and their breaking, we can unravel the deep mysteries of fundamental theories.
Topics in this Special Issue are related to symmetries and symmetry breaking in gravity, the Standard Model, and quantum gravity:
- How do symmetry principles or the lack thereof contribute to the formulation and understanding of the laws of nature and the quest for the further unification of the fundamental forces of nature?
- How does symmetry impact our understanding and modeling of black hole physics in theoretical and astrophysical contexts?
- What are the various mechanisms by which symmetry can be hidden or broken in theories, and what are their implications?
- What are the implications of spontaneous symmetry breaking, and how does it relate to phenomena such as phase transitions and the behavior of fundamental forces?
- How can we search for broken symmetries by using the Deep Underground Neutrino Experiment, the Large Hadron Collider, and gravitational wave detections?

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.
