Special Issue Information
Dear Colleagues,
Polaritons are light–matter hybrid quasiparticles. Polaritons inherit their attributes from both their light and matter constituents. More specifically, a polariton is a quantum mechanical superposition of a photon with a matter excitation, the latter being a collective mode in solids and superconducting circuits or an electron in atoms, molecules or even superconducting qubits. They can originate in different physical phenomena: conduction electrons in graphene and topological insulators (surface plasmon polaritons), infrared-active phonons in polar crystals (phonon polaritons), excitons in dichalcogenide materials (exciton polaritons), superfluidity in FeSe- and Cu-based superconductors with high critical temperature Tc (Cooper-pair polaritons), and magnetic resonances (magnon polaritons).
They offer a practical approach toward nanoscale light trapping and manipulation. Beyond nano-optical technologies, images of polaritonic standing and traveling waves contain rich insights into quantum phenomena occurring in the host material supporting polaritons, and they provide an approach toward optics-based materials research. Alongside future advances in the understanding of the physics and interactions of polaritons, solutions to application challenges may be anticipated in areas such as loss compensation, nanoscale lasing, quantum optics, and nanomanipulation.
The aim of the current Special Issue is to cover promising, recent, and novel research trends in polaritons. Areas to be covered in this Special Issue may include, but are not limited to:
- theory;
- simulation;
- characterization;
- application.

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. Crystals 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 2100 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.
