Loop Quantum Gravity and Non-Perturbative Approaches to Quantum Cosmology, Second Edition

Dear Colleagues,

Quantum gravity continues to be an active and extremely productive field of cosmology and theoretical physics. Advancements towards the unification of general relativity with quantum mechanics continue to emerge through a range of complementary approaches. New insights are being gained, offering additional clues to properties of an ultimate, underlying quantum gravity. Volume 2 of this Special Edition of Universe is devoted to the most recent developments in the field, with a special focus on loop quantum gravity/loop quantum cosmology. All related articles are invited to be submitted to Volume 2.

Topics of interest for Volume Two of this Special Issue include, but are not limited to, the following:

• Quantum geometry, quantum gravity, and cosmological implications;
• Non-perturbative approach to quantum gravity (e.g., loop quantum gravity, group field theory, spin foam);
• String theory and string cosmology;
• Modified gravity;
• Emergent gravity.

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. 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.
