Dear Colleagues,

Research in modern physics tries to unify, in a consistent context, both the guiding principles of physics and all of the fundamental interactions.

The study of problems in the frontiers of quantum field theory, like the quantization of spacetime; the issue of renormalization, algebraic, and topological quantum field theories; and the analysis of advanced quantum field theory, with reference to applications mainly of quantum gravity and quantum cosmology, to the physics beyond the standard model, and to noncommutative geometry, could open new scenarios towards the understanding of the fundamental laws of the universe.

Dark energy and dark matter conundrums, particle mixing, f(R) and scalar-tensor theories of gravity represent further systems of particular interest, both for their impact on cosmology and for their fundamental origin, which has been traced to the physics beyond general relativity and the standard model.

On the other hand, geometry and symmetry have always been a basic tool of scientific investigations, as they are two of the main ingredients in modern physical theories. Both particle physics and gravitation hugely rely on symmetry and geometry. Their application to modern physics has been immensely successful, and they will presumably play a key role even in future theories. Moreover, interferometry and the analysis of geometric invariants could reveal new aspects of nature.

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.
