Special Issue Information

Dear Colleagues,

Physical laws are Lorentz-covariant among inertial frames; namely, the form of a physical law is invariant under the Lorentz group of spacetime transformations. The Lorentz symmetry sets a fundamental constraint for physical theories and has been well incorporated in the Standard Model of particle physics. It is thus very crucial to investigate its fundamentals and its potential breaking, which would help identify the underlying physics beyond the Standard Model.

Modern precision experiments designed to test the Lorentz symmetry and the Lorentz violation have achieved spectacularly high sensitivities that demand the deepest knowledge at the Planck-scale and challenge current theories of quantum gravity. Because Lorentz symmetry is almost perfect, the theoretical framework that contains Lorentz-violating effects must necessarily modify some of the basic concepts in fundamental physics. Therefore, current research trends of the Lorentz symmetry lead to two different but related perspectives. One the one hand, a considerable amount of efforts has been spent on axiomatizing physical kinematics. These works drive us to face the problems of making fundamental physics more mathematically rigorous and logically reasonable. For example, relaxing the space isotropy can yield the Very Special Relativity, a subgroup of the Lorentz group sufficient to provide all the standard predictions in special relativity. One the other, without significantly altering the existing fundamental assumptions, effective field theories have been developed to predict observable Lorentz-violating effects. For example, the Standard Model Extension (SME) includes all possible Lorentz-violating effects but preserve the field-theoretical gauge symmetries. The SME can also contain gravitational effects and thus becomes a useful workhorse for studying phenomenological quantum gravity.

In this Special Issue of Symmetry, we solicit both fundamental and extensional research works following the modern trends in Lorentz symmetry and Lorentz violation. We expect the completed issue can provide an overview of current theoretical and experimental efforts in understanding one of the most treasured Lorentz-symmetry physics.

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.
