Special Issue Information

Dear Colleagues,

Paul A. M. Dirac spent his entire working life trying to reconcile quantum mechanics with special relativity. His equation for the electron and positron is a case in point. Indeed, the Dirac equation is the correct language for the electron spin in the Lorentz-covariant world and has application to the present day study of neutrinos. Dirac was also interested in particles with space-time extensions and their internal space-time symmetries. This became the major issue when the proton became a bound state of the quarks. What happens when the proton moves with speed close to that of light? This and many other problems can be investigated according to the suggestions made by Dirac during the period from 1927 to 1963. This special issue can include the papers on the Dirac equation, higher-spin particles in the relativistic world; symmetries of the hydrogen atom and harmonic oscillators; neutrinos both massless and with small mass; standing waves, and string models in the Lorentz-covariant regime.

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 papers will be 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 1400 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.
