Parity-Time (PT) Symmetry in Classical and Quantum Domains

Dear Colleagues,

Symmetries play an essential role in determining the constraints that all physical systems—classical or quantum, open or isolated—must abide by. Continuous symmetries manifest themselves through corresponding conserved quantities (charges) and provide global information about the dynamics of a system. In open systems (where energy, momentum, or mass conservation may not hold), the role played by symmetries, if any, is even more important. In recent years, open systems with a “balanced gain and loss”, called parity-time (PT) symmetric systems, have become a subject of intense research. With well-established realizations in the classical domain and emerging ones in the quantum domain, PT-symmetric systems will continue to be explored across greater depth and breadth in the coming years.

This Special Issue will be focused on recent advances in the field of PT-symmetry in the classical and quantum domains. We particularly encourage your contributions in the following topics: (1) Experimental realizations, (2) PT-systems with interactions and nonlinearities, (3) conservation laws in PT systems, (4) PT-symmetry-enabled applications, and (5) pedagogical reviews.

If you have any questions, please contact any of us.

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 250 words) can be sent to the Editorial Office for assessment.

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.
