Special Issue Information
Dear Colleagues,
The physics of black holes has been a fascinating topic in the scientific community since their theoretical formulation about a century ago. Since then, we have learned many characteristics that make them some of the most intriguing objects in the universe. However, even after all this time, there are still many issues we need to address. At the classical level, there are astrophysical predictions regarding the bounds on their masses, as well as the processes that give rise to supermassive black holes at very early stages in the evolution of the universe, which we do not yet fully understand. At the semiclassical level, the ongoing debate about resolving the information paradox implied by the Hawking radiation process continues, although the fundamental reason likely lies at the quantum level. Indeed, black holes are objects from which we can gather profound insights into quantum gravity. A prototypical example is clearly the Bekenstein–Hawking association of entropy with the event horizon area, which suggests the existence of quantum degrees of freedom underlying a black hole. Within the context of string theory and field theory, many of these issues have been addressed, proposing a range of potential solutions to these puzzles. The presence of extra dimensions, supersymmetry, and the holographic principle has opened up a plethora of possible solutions and interesting lines of research. Black hole physics provides a direct window into visualizing the structures of quantum gravity. As suggested by the swampland program within string theory, the study of symmetries associated with black holes represents a promising avenue for improving our current understanding of the fundamental quantum properties of spacetime.
The aim of this Special Issue is to collect some reviews and original research articles showing the advance of our knowledge about the physics of black holes at the quantum and semiclassical level within the framework of string and field theory.

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.
