Special Issue "Thermalization in Isolated Quantum Systems"
A special issue of Entropy (ISSN 1099-4300).
Deadline for manuscript submissions: closed (31 July 2019).
The field of mesoscopic physics is going through rapid development with contributions from many subfields of science including atomic, molecular and nuclear physics, condensed matter physics on the micro- and nano-scale, biophysics and quantum information. In all cases, we have to deal with relatively small systems of interacting constituents where statistical features are clearly emerging being described in terms of temperature, entropy, etc., while at the same time one still can study, theoretically and experimentally, individual quantum states.
If traditional statistical physics usually considered statistical ensembles in the limit of infinitely large volume and particle number, and the equilibrium thermalization was reached due to the interaction with a thermostat, in a small system with a finite number of particles thermal equilibrium is established as a result of interparticle interactions which, at high level density, leads to chaotic mixing of simple many-body configurations. Historically this follows the line from Boltzmann to Landau and Lifshitz who stressed in their Statistical Physics that statistical properties can be observed and studied on the level of individual quantum states. This direction of science addresses the emergence of thermodynamic phenomena from quantum mechanics and quantum chaos creating in a sense a new paradigm of statistical mechanics.
This emerging field encompasses different bright ideas and very wide practical applications; its interdisciplinary character leads to different viewpoints and illuminating discussions. We, therefore, solicit contribution to this Special Issue on a new branch of quantum physics and its applications.Prof. Dr. Vladimir Zelevinsky

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 papers will be 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. 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 1600 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.
