Modified Gravity Cosmology: From Inflation to Dark Energy

Dear Colleagues,

In addition to inflation in the early universe, the current cosmic acceleration has been found by observations of Type Ia Supernovae. Provided that the universe is flat, there should exist a component whose pressure is negative, which is called “dark energy”. This is one of the most fundamental issues in modern cosmology. The approaches to explain this phenomenon are classified into two representative categories. First is the introduction of dark energy in general relativity. Second is the modification of gravity at large distances. The latter is called geometrical dark energy. The aim of this special issue is to reveal the modification of gravity and the properties of dark energy to realize the late-time accelerated expansion of the universe. Furthermore, our scope involves the foundations of physics in order to understand the mechanism of cosmic acceleration, such as particle physics theories, quantum field theories, and string theories. We are very pleased to receive submissions to this special issue on modified gravity theories, dark energy models, and related fundamental 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 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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. 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.
