Special Issue Information

Dear Colleagues,

A black hole is an empty region. Anything in a black hole region cannot stay at a constant, proper distance from the center, but has to fall towards the center. In ordinary laboratory physics, we cannot regard an empty region solely as a system that forms some physical state (such as a thermal equilibrium state). Therefore, Hawking’s discovery that thermal radiation is emitted from the surfaces of black hole regions (i.e., black hole horizons) is astonishing. The black hole has to be regarded as a thermal equilibrium system. The fact that Hawking’s radiation is predicted by quantum field theory in the context of black hole spacetime implies that the black hole is a thermal equilibrium state of the underlying quantum gravity.

It is expected that the black hole is regarded as some thermal equilibrium system composed of microscopic constituents of spacetime. Such microscopic constituents should cause the black hole’s entropy. Bekenstein's proposal implies that black hole entropy is given by a quarter of the surface area of the black hole horizon (in Planck units). This is the entropy-area law of black hole. This law should include at least the following two ingredients: (1) the nature of microscopic constituents of spacetime (in other words, microstates of underlying quantum gravity), and (2) the statistical mechanical property of long range interaction systems, since gravity is a long range interaction.

This Special Issue “Entropy and Spacetime” can be a meeting place for statistical mechanics, thermodynamics, black hole, and spacetime physics. Further, both classical and quantum approaches are possible. Contributions from both gravitational and statistical physics are welcome.

Submission

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy 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 1200 CHF (Swiss Francs).
