Bridging the Gap between Cosmological Models and Observable Tensions: From Classical to Quantum Approaches to Cosmology

Dear Colleagues,

In the realm of cosmology, the interplay between theoretical models and observations has given rise to a series of unexpected tensions. Moreover, the current understanding of the standard LCDM paradigm is lacking of something as the model seems to be in conflict also with the most recent James Webb satellite results. On the other hand, the origin of the cosmological constant does not find resolution into quantum field theories, predicting a very different value that does not align with cosmological observations. This Special Issue focuses on how to bridge the gap between divergent theoretical models, even extending the LCDM framework with some sorts of dark energy approaches, and the observable universe. Dealing with classical and quantum scenarios applied to cosmology, we expect a collection of articles exploring the various methods employed to harmonize these disparities and uncover the hidden connections that bring cosmological models and observable tensions into alignment.

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.
