Physica A is a peer-reviewed journal that publishes research on statistical mechanics and how its methods explore to real systems
Physica A: Statistical Mechanics and Its Applications is a scientific journal published by Elsevier that focuses on the physics of systems with many interacting parts — everything from gases and liquids to networks, economics, and biology. The journal accepts original research papers, reviews, and letters that use statistical mechanics frameworks to solve problems in physics, chemistry, materials science, and other fields.
The journal has been published since 1975 and appears roughly twice a month. It is indexed in major databases including Web of Science and Scopus, which means libraries, universities, and researchers can find articles through standard academic search tools. Most articles are behind a paywall, though some institutions and individual researchers have open access through their subscriptions or author agreements.
If you are a researcher deciding where to submit work, a student looking for papers on a specific topic, or someone trying to understand what a particular journal covers, this guide explains what Physica A publishes, how to find articles in it, and what role it plays in the broader research landscape.
Key Takeaways
- Physica A publishes peer-reviewed research on statistical mechanics and its applications to physical, biological, and social systems.
- The journal accepts original research papers, review articles, and shorter letters, with a typical review process lasting several months.
- Articles are searchable through Scopus, Web of Science, and the journal's own website, though most require institutional or paid access to read in full.
- Researchers typically submit through Elsevier's online submission system and can track their manuscript's status from submission through acceptance or rejection.
- The journal is indexed by major academic databases, so citations to Physica A articles count toward research impact metrics used by universities and funding agencies.
What kinds of research Physica A publishes
Physica A focuses on statistical mechanics — the branch of physics that describes how systems with billions or trillions of particles behave — and on methods that grew out of statistical mechanics but now explore to other fields. This includes classical statistical mechanics (gases, liquids, phase transitions), quantum statistical mechanics, and applications to networks, economics, social systems, and biology.
The journal accepts papers on topics like polymer physics, critical phenomena, Monte Carlo simulations, complex networks, econophysics (using physics methods to study economics), and biological systems modeled as statistical ensembles. It also publishes review articles that summarize the state of knowledge in a particular area, and shorter communications for preliminary or time-sensitive findings.
The journal does not typically publish purely theoretical mathematics papers without a physics process, nor does it focus on experimental work in the traditional sense — though it does publish papers analyzing experimental data using statistical mechanics frameworks. If you are unsure whether your work fits, the journal's website lists the scope in detail and the editorial office can answer specific questions before you submit.
How to find articles in Physica A
The most direct route is the journal's website at sciencedirect.com, where you can browse issues by date or search by keyword, author, or article title. If you have institutional access through a university or research library, you can read the full text of any article. If you do not, you can usually see the abstract and reference list for free.
Scopus and Web of Science are the two largest academic databases and both index Physica A. You can search these databases by topic and filter results to show only Physica A articles, or you can see how many times a particular Physica A article has been cited by other researchers. Most universities provide free access to at least one of these databases for students and faculty.
If you find an article you need but cannot access it, you can contact the author directly — most researchers will send you a copy if you ask. Your university library may also offer interlibrary loan, where they request the article from another library. Some authors also post copies on their personal or institutional websites or on preprint servers like arXiv, though not all do.
The peer review process and timeline
When you submit a manuscript to Physica A, an editor first checks whether it fits the journal's scope and meets basic quality standards. If it passes this check, the editor sends it to two or three peer reviewers — other researchers in the same field who read the paper anonymously and provide detailed feedback. This process typically takes two to four months, though it can be faster or slower depending on how quickly reviewers respond.
The reviewers may recommend acceptance, minor revisions, major revisions, or rejection. If revisions are requested, you resubmit with a letter explaining how you addressed each comment. The editor may send the revised version back to reviewers, or may make a decision based on your response. The entire cycle from initial submission to final acceptance usually takes four to eight months, though some papers are rejected without revision and others require multiple rounds of revision.
Once your paper is accepted, it goes through copyediting and typesetting before being published online. Physica A publishes articles online as soon as they are ready, rather than waiting for a full print issue, so your work becomes citable within weeks of acceptance.
How to submit your own research to Physica A
Submissions go through Elsevier's Editorial Manager system, which you access at the journal's website. You create an account, upload your manuscript and figures, and fill in metadata including the title, abstract, keywords, and suggested reviewers. The system guides you through each step and saves your progress if you need to return later.
Before you submit, read the journal's author guidelines, which specify formatting requirements, reference style, and the types of files accepted. Most journals ask for a PDF of your manuscript and separate high-resolution image files. You will also need to declare any conflicts of interest and confirm that your work has not been published elsewhere.
After submission, you receive a confirmation email with a manuscript number. You can log back into the system at any time to check the status — whether it is under review, with reviewers, or awaiting your revision. The journal will also send you emails at key milestones, such as when a decision is made or when your revised manuscript is received.
Who reads Physica A and why it matters for your research
Physica A is read by physicists, mathematicians, and researchers in applied fields like economics, biology, and computer science who use statistical mechanics methods. It is a well-established journal with a solid reputation, so publishing there signals to other researchers that your work has passed peer review and meets professional standards. Universities and funding agencies use publication records to evaluate researchers, and citations to your work in Physica A count toward these metrics.
The journal is not the highest-impact physics journal — that distinction belongs to publications like Nature, Science, or Physical Review Letters — but it is a respected venue in its specific area. If your work is on statistical mechanics or its applications, Physica A reaches the right audience. If your work is on a different topic, a different journal might be more appropriate.
The journal's impact factor — a measure of how often its articles are cited on average — varies year to year but typically falls in the range of 2 to 3, meaning the average Physica A article is cited about 2 to 3 times in the first two years after publication. This is moderate for physics journals and reflects that the journal serves a specialized but active research community.
Open access and how to read Physica A articles without a subscription
Most Physica A articles are behind a paywall and require either an institutional subscription or a personal purchase. However, several routes exist to read articles for free or low cost. If you are affiliated with a university or research institution, check whether your library has a subscription — most do for major journals. Your library's website usually has a search tool that tells you whether you have access to a particular journal.
Some authors pay an open access fee when their paper is accepted, which makes the article free to read for everyone. This fee is typically several thousand dollars and is often paid by the author's institution or funding agency rather than by the author personally. You can usually tell whether an article is open access by looking for an open access label on the article page.
Preprint servers like arXiv allow researchers to post versions of their papers before or after peer review. Not all Physica A authors do this, but many do, especially in physics and mathematics. You can search arXiv by topic and often find a free version of a paper that was later published in Physica A. The preprint version may differ slightly from the final published version, but the content is usually the same.
Frequently Asked Questions
How long does it take to get a decision on a manuscript submitted to Physica A?
The initial decision typically comes within two to four months of submission, though this varies. If revisions are requested, you usually have one to three months to resubmit. The entire process from submission to acceptance or rejection usually takes four to eight months. You can check the status of your manuscript at any time through the Editorial Manager system.
Can I submit the same paper to Physica A and another journal at the same time?
No. Journals require that you submit your work to only one place at a time. If you submit to Physica A, you must wait for a decision before submitting elsewhere. If your paper is rejected, you are free to submit it to another journal. If it is accepted, it is published in Physica A and cannot be published elsewhere without permission.
What is the difference between Physica A and other physics journals?
Physica A specializes in statistical mechanics and its applications, so it is the right fit if your work uses statistical mechanics methods. If your work is in particle physics, astrophysics, or experimental condensed matter physics, a different journal might be more appropriate. The journal's website describes its scope in detail, and the editorial office can advise whether your work is a good fit.
Do I need to be affiliated with a university to submit to Physica A?
No. Independent researchers can submit to Physica A. However, you will need an email address and access to the internet to use the submission system. Some independent researchers may have difficulty accessing peer-reviewed literature to cite in their work, so you may want to check whether your local library offers public access to academic databases before you begin writing.
Is Physica A the same as Physica B or Physica C?
No. Physica A, B, and C are three separate journals published by Elsevier under the Physica brand. Physica B focuses on condensed matter physics and materials, while Physica C focuses on superconductivity. Physica A is the one dedicated to statistical mechanics and its applications. Make sure you are submitting to the correct journal for your work.
