From Fundamental Fields to Information and Emergent Phenomena: Theory and Applications of Quantum Electrodynamics

Dear Colleagues,

Quantum electrodynamics (QED), the electromagnetic component of the Standard Model, is regarded as the most precisely tested quantum field theory (QFT) to date. Originally formulated to describe fundamental interactions among electrically charged particles and radiation, QED also provides the basis of effective theoretical descriptions in a variety of systems, including quantum and topological materials. Recent developments in information theory, non-equilibrium dynamics, and emergent phenomena in quantum systems have further expanded the conceptual framework and applications of QED-inspired approaches.

This Special Issue aims to bring together theoretical and applied contributions that explore electromagnetic quantum systems as carriers of information and platforms for emergent behavior. Topics of interest include, but are not limited to, information-theoretical approaches to QFT, entropy in electromagnetic environments, effective QED descriptions of Dirac and Weyl materials, and broader theoretical perspectives linking QED to effective field theories and the Standard Model.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy 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 2600 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.
