Interests: Symmetry, symmetry breaking, chirality, duality, helicity. In general, theoretical physics and its applications.
Symmetry is one of the most general concepts in physics. Symmetry arguments are used to explain and predict observations at all length scales, from elementary particles to cosmology. The generality of symmetry arguments, often combined with simplicity, makes them a powerful tool for both fundamental and applied investigations. In electrodynamics, one of the symmetries is the invariance of the equations under exchange of electric and magnetic quantities. The continuous version of this symmetry is most commonly known as electromagnetic duality symmetry. It has been known for more than a century, and, throughout this time, has influenced other areas of physics, like high energy physics and gravitation. Duality symmetry is inherently attached to its generator and conserved quantity, helicity, which is yet another concept that transcends electrodynamics.
In recent years, duality, and helicity have been receiving renewed attention in their original electrodynamic context. Their conservation law has been reconsidered, analyzed, and quantified from different points of view, and convenient numerical tools have been developed for it. Helicity is also being used in the description of chiral particles with spin, and as an alternative to the electric/magnetic description of fields and interactions. Most of the time, the material system is not symmetric under duality transformations, the symmetry is broken, and the interaction with matter mixes the two possible helicities of the electromagnetic field. Yet, material structures that, at least to good approximation, restore the breaking of the symmetry are being proposed for different applications: zero-backscattering nanoparticle arrays, artificial optical activity, enhanced circular dichroism measurements, and protected photonic edge states, among others.
In this Special Issue, we aim to gather contributions from electrodynamics and also other fields that consolidate and enlarge the usability of duality and/or helicity with regard to both applied and fundamental questions.

Manuscripts can be submitted until the deadline. All papers will be 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 1400 CHF (Swiss Francs).
