Special Issue Information
Dear Colleagues,
Today, black hole thermodynamics is regarded as one of the most profound connections between classical gravity, quantum physics, and statistical physics. It began as a formal analogy between the laws of black hole mechanics and classical thermodynamics but has evolved into an essential ingredient of modern theoretical physics, which is changing our understanding of spacetime, entropy, and information.
Over the past decades, black hole thermodynamics has expanded far beyond its original classical and semiclassical formulations. Important results have been achieved, aiming to understand the entropy of black holes from a statistical point of view and to formulate and develop a quantum theory of gravity. Moreover, the application of mathematical tools such as thermodynamic geometry and geometrothermodynamics (GTD) has opened new windows for understanding the stability properties and the phase-transition structure of black holes.
This Special Issue is particularly significant, as it coincides with 2027, marking the 20th anniversary of the formal proposal of geometrothermodynamics. Since its initial formulation, GTD has provided a robust Legendre-invariant framework to describe the properties of thermodynamic systems through differential geometry, proving especially fruitful in the study of black hole thermodynamics.
This Special Issue is devoted to conceptual, technical, and observational aspects of black hole thermodynamics. Topics of interest include but are not limited to thermodynamic variables, phase transitions, extended thermodynamics, stability properties, and critical coefficients of black holes in any dimension. This Special Issue aims to capture the main aspects of current research in black hole thermodynamics. Contributions should address classical and semiclassical foundations, quantum and statistical interpretations, geometric formulations, non-equilibrium processes, and emerging connections with quantum information and complexity theory. Particular attention will be given to the interrelation between thermodynamic geometry and geometrothermodynamics with the concepts of entropy and microscopic structure, as well as to recent advances clarifying the thermodynamic properties of black holes in modified and generalized theories of 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 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-anonymized 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 2600 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.
