Special Issue Information
Dear Colleagues,
Cavity magnonics—the emerging interdiscipline of cavity quantum electrodynamics and magnonics—has been rapidly developing in recent years. Cavity magnon-polaritons (CMPs) are a new type of bosonic quasiparticles caused by the hybridization of magnons and cavity photons, which has been detected and characterized via the anti-crossing transmission spectrum. The entangled spin orientation and photon number state in CMPs enables an efficient quantum information transfer between photon and magnon via Rabi oscillation, which is promising for quantum computing.
Recently, non-Hermitian physics and parity-time symmetry have attracted considerable attention. The non-Hermitian Hamiltonians allow the entirely real spectrum as long as the combined parity (P) and time (T)-reversal symmetries are respected. The non-Hermitian singularities, called exceptional points, have been experimentally observed in the cavity magnonic system. Conventional CMPs have a finite lifetime due to the intrinsic losses of photons and magnons. Pumping the cavity to compensate the dissipation may extend the coherent time of a CMP and lead to a dynamical equilibrium. Such a system can be described by a non-Hermitian Hamiltonian, with the hallmark of a non-Hermitian system being the singularity degeneracy and a collapse of the dimensionality in the eigenspace. This property may significantly modify the properties of polaritonic modes and the transmission spectrum. PT-symmetric CMPs and more general non-Hermitian CMPs, such as anti-PT symmetric and anyonic-PT symmetric CMPs, are seeking opportunities toward both scientific curiosity and new technological innovations.

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.
