Special Issue "String Field Theory and Nonlocal Gravity"
Deadline for manuscript submissions: 29 February 2024 | Viewed by 6324
One of the main paradigms of modern theoretical physics is the belief that the string theory unifies all known forces and governs the fundamental law of Natures. From this point of view questions in cosmology, related to fundamental physics should be addressed within the string scenario framework. The appearance of nonlocality within the string field theory framework is a good motivation for studying nonlocal cosmological models.
Modified gravity models have been proposed with the hope to find resolutions to the important open problems of General Relativity. One of these problems is the construction of quantum gravity. A possible modification that allows getting a renormalizable theory of quantum gravity including the addition of higher-derivative terms to the Einstein-Hilbert action. Unfortunately, models with the higher-derivative terms have ghosts. In the present time, nonlocal gravity models are considered a possible way to overcome this problem. The role of higher derivatives and nonlocality in the quantization of gravity is actively discussed.
Local modified gravity models that are compatible with the observation data describe the different stages of the Universe evolution from inflation to the late-time accelerating expansion. Nonlocal generalizations of such models are actively investigated. Please note that all submitted papers must be within the general scope of the Symmetry journal.

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.
