Special Issue Information

Dear Colleagues,

Topological phenomena have been widely discussed in recent years, involving research fields ranging from Hermitian systems to non-Hermitian systems, from satisfying Euclidean geometry to non-Euclidean geometry. When studying topological phenomena, symmetry plays a very important role. The topological phase transition emerges, accompanying the change in symmetry. Especially when extended to non-Hermitian or non-Euclidean systems, the novel topological phenomena have a close relation with special symmetries.

The relationship between topological phenomena and symmetry is not only limited to theoretical discussions, but has also been extensively elaborated on multiple experimental platforms, for example, condensed matter materials, cold atoms, superconducting systems, optical platforms, acoustic crystals, electric circuits, etc. On these platforms, by measuring the corresponding physical quantities specific to the platform, it is possible to demonstrate the changes in topological properties as symmetry changes. Moreover, observing the relationship between topological phase and symmetry can not only verify the correctness of the theory, but also provide guidance for topological-related functional devices through symmetry.

The goal of this Special Issue is to explore the effects of symmetry and asymmetry on topological phases. Manuscripts may include (but are not limited to) the explicit discussion of the relation between symmetry/ asymmetry and topology; the prediction of topology with the aid of machine learning and other computation skills; studies conducted nder non-Hermitian or non-Euclidean geometry conditions; the effects of symmetry and asymmetry on topology, including changes in topological states, topological phase transitions, and topological functional devices; experimental verification of the relationship between symmetry/asymmetry and topological phases.

Please note that all submissions should fit the scope of the Symmetry journal.

We look forward to receiving your contributions.

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.
