About the journal


Aimed primarily at mathematicians and physicists interested in research on nonlinear phenomena, the journal’s coverage ranges from proofs of important theorems to papers presenting ideas, conjectures and numerical or physical experiments of significant physical and mathematical interest.

Subject coverage

The journal publishes papers on nonlinear mathematics, mathematical physics, experimental physics, theoretical physics and other areas in the sciences where nonlinear phenomena are of fundamental importance. A more detailed indication is given by the subject interests of the Editorial Board members, which are listed in every issue of the journal.

Due to the broad scope of Nonlinearity, and in order to make all papers published in the journal accessible to its wide readership, authors are required to provide sufficient introductory material in their paper. This material should contain enough detail and background information to place their research into context and to make it understandable to scientists working on nonlinear phenomena.

Nonlinearity is a journal of the Institute of Physics and the London Mathematical Society.

Why should you publish with Nonlinearity?

  • Impact Factor: included in Clarivate Analytics’ Journal Citation ReportsⓇ.
  • High standards: timely peer-review guided personally by the Editorial Board.
  • Excellent author service: a friendly and helpful team are readily available to answer your questions (
  • Open access options: authors may choose to publish their paper openly in the journal (conditional on payment of an APC) or to host manuscript versions via a repository.
  • Society publisher: published by IOP Publishing, a publisher central to the Institute of Physics (IOP) and a world leader in professional scientific communications. IOP is a not-for-profit society and registered charity that works to advance physics research, application and education.

Article types

Nonlinearity welcomes submissions of the following article types:

  • Research Papers: reports of original research work. The main criterion for acceptance will be the existence of a significant contribution to the general mathematical or physical understanding of nonlinear systems.
  • Invited Articles: commissioned by the Editorial Board.

Special requirements

Article style

NJP publishes only original research. As a journal serving the whole physics community, article abstracts, introductions and conclusions should be accessible to the non-specialist, stressing any wider implications of the work within physics. However, the main body should not compromise on the scientific rigour and detail demanded by an international physics research journal. The broad readership that NJP attracts gives authors an opportunity to convey to a wider audience, as well as to specialists, the importance of the work.

Authors are encouraged to take full advantage of the electronic medium to include colour, video, audio or other innovative presentation formats and links to more extensive tutorial information or data. However, use of such presentation techniques is not a criterion for article acceptance, and should only serve to effectively communicate the physics.

Article length

As NJP is an electronic-only journal, NJP articles have no rigid length restrictions. They should contain sufficient technical detail for an expert reader to understand and assess the methods and results. However, the NJP Editors do encourage authors to be concise, and short, high-quality articles are welcome. Articles should not normally be longer than 18,000 words (an A4 size journal page contains an average of 900 words).

Article title and abstract

To be suitable for NJP all articles must be accessible to and of interest to NJP’s broad readership. Article titles and abstracts should be written with this in mind. Specifically, both should be kept as short and non-technical as practicable, and the abstract should make clear the wider significance and interest of the work.

Citing an article in NJP

NJP uses an article numbering system which allows articles to be published one at a time, while maintaining separate sections for editorial material and focus issue articles. Articles should be referenced by using the six-digit article number in place of a page number, for instance:

Reece M 2013 New J. Phys. 15 043003

The pages in the PDF file of each article are numbered from 1. These page numbers should not normally be included in a reference. However, if it is desirable to indicate the length of an article, this can be done by including the number of pages, in parentheses, after the article number, for example:

Reece M 2013 New J. Phys. 15 043003 (21pp)

Each article in a volume has a unique six-digit number, the first two digits indicate the month in which the article has been published, the next two the type of article and the final two are a counter indicating the sequence number for the article within its month and category.

Video abstracts

New Journal of Physics was the first journal to include video abstracts, back in 2011. All authors are invited to submit a video abstract to be published alongside their article manuscript.

Video abstracts are aimed at increasing your visibility and that of your work. Through this medium, you can go beyond the constraints of the written article to personally explain the importance and value of your work to the journal’s audience.

Video abstracts should enhance a reader’s understanding and appreciation of an article through accessible and engaging presentation of the main results and conclusions reported.

Please see the general IOP Publishing guidelines page for technical guidance on creating a video abstract.

Please see more information, a ‘how to’ here and some examples here.


Interactive figures

Including interactive figures in your article can enhance the communication of your research, add clarity, and give the reader the ability to manipulate the information contained in an image.

For guidelines on how to create and submit interactive figures please see our guide on Publishing Support.

General scientific summaries

Authors are encouraged to submit a general scientific summary to accompany their work. The purpose of this additional feature is to increase the accessibility of articles in NJP to a broad, non-specialist readership, and to raise the overall visibility and understanding of the journal’s content.
