The Journal of Statistical Mechanics: Theory and Experiment (JSTAT) is the third international, peer-reviewed, online-only journal created by the International School for Advanced Studies (SISSA) and the Institute of Physics Publishing (IOP Publishing), following the success of JHEP and JCAP. SISSA is in charge of the peer review of submissions, while IOP Publishing is in charge of the online publication of articles and subscriptions.


JSTAT is targeted to a broad community interested in different aspects of statistical physics, which are roughly defined by the fields represented in the conferences called Statistical Physics that are held every three years. Submissions from experimentalists working on all the topics which have some connection to statistical physics are also strongly encouraged. JSTAT therefore features both theoretical and experimental articles.

JSTAT As far as timing for publication is concerned, JSTAT is committed to ensuring a fast review process. It aims at publishing papers within 8 weeks. The topics covered by the Journal are listed below. Each topic has its own list of keywords.

JSTAT Keywords
1. Exact results
2. Quantum mechanics and quantum field theory
3. Phase transitions and critical phenomena
4. Non-equilibrium processes
5. Fluids, instabilities, turbulence, reaction dynamics, soft and granular matter
6. Surfaces, interfaces, growth processes
7. Disordered systems and glassy matter
8. Statistical mechanics of complex materials
9. Interface biology-physics
10. Information theory, combinatorial optimisation, graphs and networks
11. Collective phenomena in economic and social systems

The Journal's scope should not be regarded as fixed and will evolve and adapt over time to the changes in research trends.

Editorial policy

From the outset the journal's main aim was to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal.

Consequently the Scientific Directors and the Editorial Board, composed of distinguished scientists in the field, jointly establish with the Chief Scientific Director the journal's scientific policy and ensure the scientific quality of accepted articles. Editors and referees operate anonymously, but they can reveal their identity to the authors if they so wish.

When submitting a paper to the Journal, contributors must look up the JSTAT list of keywords and choose the ones that best define the subject of their work. The JSTAT system will then automatically assign the submission to a member of the Editorial Board by choosing the best match of the author's keywords with the areas of expertise of the available editors, taking editor workload into account. Editors take full responsibility for the submission, either reviewing the preprint themselves or sending it to as many referees as may be necessary. Editors may also consult a fellow member of the Editorial Board. The criteria for acceptance are scientific quality, originality and relevance. Length should be appropriate to the information presented. Editors are asked to apply a strict quality filter in selecting contributions for publication. Editors and referees generally operate anonymously, but are free to reveal their identity to the authors if they so wish.

Lastly, JSTAT also publishes Special Issues (Focus or Topical Issues).

Contributions submitted to JSTAT must not have been published or be under consideration for publication in other refereed journals, nor should they be sent to other journals while still being considered for publication in JSTAT.

Organisation chart

JSTAT is organised as follows:

  • Chief Scientific Director
  • Scientific Directors
  • Editorial Board
  • Editorial Office at SISSA Medialab
  • Publishing Office at IOP Publishing

The Chief Scientific Director is in charge of coordinating the activity of the Scientific Directors and monitoring the quality of the journal.

The Scientific Directors are in charge of supervising the Editorial Board and monitoring the quality of the journal jointly with the Chief Scientific Director. The Scientific Directors are first instance for an appeal in cases of disagreement between Authors and Editors.

The Editorial Board is JSTAT's most important asset. Editors are in charge of the peer-review of submissions and take themselves the final decision on whether or not to publish a contribution. JSTAT has a large Editorial Board, in order to provide competent coverage for all the areas indicated by the keywords and thus avoid generic decisions or the inappropriate selection of referees. The Editor-in-charge takes full responsibility for the article. (S)he can assess it him/herself or send it to one or more referees.

The Editorial Office is in charge of supervising the functioning of the Journal in collaboration with the Editorial Board. SISSA Medialab, where the Editorial Office is based, runs the software system that automates the editorial process.
The Editorial Office monitors the journal daily, provides assistance to authors, editors and referees, and takes action in close collaboration with the Scientific Directors in the event of any problems or delay that may arise.

The Publishing Office at IOP Publishing is responsible for the marketing and distribution of the Journal, including the typesetting and publication of accepted contributions. As for archive preservation, IOP Publishing and SISSA are committed to maintaining the archive (i.e. through LOCKSS and taking appropriate steps in the event of signifcant technology changes.

JSTAT software

JSTAT is a joint SISSA-IOP Publishing publication. SISSA controls the peer-review of submitted manuscripts, while IOP Publishing is in charge of the publication of articles, which can be read and downloaded at http:/ The editorial website is hosted at SISSA (, where a web-based software system has been developed and is used to process submissions and the entire editorial procedure: the submission of preprints, their automatic assignment to the appropriate editors, the review by referees, the contacts between editors, referees and the Editorial Office, the revision of contributions and the delivery of accepted articles to the Publishing Office at IOP Publishing, as well as the administration of the journal. Editors, referees and authors have their personal web pages, where they take action or check the status of preprints.

The system developed at SISSA relies on a powerful database that stores the files of the contributions, their metadata and, most importantly, all the correspondence between the journal users (authors, editors, referees, the editorial office and the typesetters). Authors, editors and reviewers therefore have direct access to all the information, files and correspondence items appropriate for their role on their personal web pages. All users have a single username and password to access their home page on the JSTAT website for all of their different roles (author, editor or referee).

JSTAT is available online through IOP Publishing's Electronic Journals service. Contributions are published as soon as they are available in their final form. Online publication offers enhanced features and functions:

  • Powerful search engines replace the table of contents and indexes used by paper journals. Readers can `cluster' search results by topic.
  • Extensive reference linking. IOP Publishing is part of CrossRef and also has bilateral reference-linking agreements with other physics publishers.
  • Contributions, published in two different file formats (PDF and HTML), are hypertextual, with links within the articles themselves and to the articles quoted in the references.
  • Multimedia. JSTAT encourages authors to submit multimedia files to enhance the online version of published research articles. Multimedia enhancements typically consist of video clips, animations or supplementary data.
