Special Issue Information

Dear Colleagues,

Gravitational physics and symmetry are fundamental areas of research in modern physics, providing insights into the nature of the universe and the fundamental forces that govern it. From Einstein's theory of general relativity to the study of black holes, gravitational waves, and cosmology, this field has revolutionized our understanding of space, time, and matter. Symmetry, on the other hand, plays a crucial role in theoretical physics, offering a framework to understand conservation laws, particle interactions, and the unification of forces. The interplay between gravitational physics and symmetry continues to inspire groundbreaking research, making it a vital area of study with profound implications for both theoretical and experimental physics.

This Special Issue aims to bring together cutting-edge research and reviews in the field of gravitational physics and symmetry. The objective is to provide a platform for researchers to share their latest findings, foster collaboration, and explore new directions in this dynamic field. The subject aligns with the journal's scope by focusing on the theoretical and experimental aspects of physics, particularly those that contribute to our understanding of fundamental forces and the structure of the universe. The scope of this Special Issue is carefully defined to ensure a focused yet comprehensive collection of articles, targeting at least 10 high-quality contributions. If this goal is achieved, the Special Issue may also be published in book form, further enhancing its impact.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Gravitational waves and their detection;
  • Black hole physics and singularities;
  • Cosmology and the large-scale structure of the universe;
  • Theoretical developments in general relativity;
  • Symmetry principles in gravitational theories;
  • Quantum gravity and the unification of forces;
  • Experimental tests of gravitational theories;
  • Applications of symmetry in particle physics and cosmology;
  • Mathematical frameworks for symmetry and gravitation;
  • Interdisciplinary approaches to gravitational physics and symmetry.

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.

Scalar–tensor theories have shown promise in many sectors of cosmology. However, recent constraints from the speed of gravitational waves have put severe limits on the breadth of models such classes of theories can realize. In this work, we explore the possibility of a Horndeski Lagrangian that is equipped with two dilaton fields. The evolution of a two-dilaton coupled cosmology is not well known in the literature. We explore the tensor perturbations in order to assess the behavior of the model against the speed of the gravitational wave constraint. Our main result is that this model exhibits a class of cosmological theories that is consistent with this observational constraint. Full article
