Special Issue Information
Dear Colleagues,
Symmetry is an essential concept for understanding the laws of nature. In physics, it constitutes one of the conceptual pillars on which rests the understanding of an enormous variety of phenomena of various scales, including classifications of equilibrium phases and phase transitions in condensed matter physics. Recent years have witnessed a new role of symmetry in characterizing nonequilibrium dynamics, particularly in many-body quantum systems. A physicist's approach is to study such dynamics employing the simplest possible protocols, including (but not limited to) periodic driving (Floquet systems), instantaneous quench of parameters, ramping a parameter with time (annealing/finite rate ramps), and application of a finite bias across a system. There has been rapid growth and exciting discoveries in the field of nonequilibrium quantum dynamics in the last decade. Some noteworthy examples are Floquet many-body localized systems hosting exotic phases, such as discrete time crystals, many-body quantum chaos in periodically kicked systems, dynamical phases of non-Hermitian topological models, and dynamically frozen states in disorder-free systems. Symmetry manifests in various avatars in these examples, such as the emergent symmetry of the dynamics controlling either timescale to reach chaos or stabilization in dynamically frozen states and new topological classification of phases via the unification and ramification of different symmetries in non-Hermitian systems, to name a few. This is a collection of articles from authors connected to these developments at the frontier level.

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.
