Where to Submit Your Manuscript

Submit manuscripts via Peer X-Press, the journal's online manuscript submission system, located at http://chaos.peerx-press.org.

Author instructions are available through a link after you successfully log into Peer X-Press. After registering and submitting information and files, you may use Peer X-Press to check on the status of your manuscript throughout the peer review process.

A cover letter should specify authors, title, Journal, corresponding author's e-mail address, and any special requests.

Unless otherwise stated, submission of a manuscript will be understood to mean that the paper has been neither copyrighted, classified, published, nor is being considered for publication elsewhere.

Agreement to the terms of AIP’s Transfer of Copyright Agreement form is required for publication in this journal. No claim is made to original U.S. Government works. When submitting your original or revised manuscript to the journal's online submission site (http://chaos.peerx-press.org), you will be able to provide electronic consent to the Transfer of Copyright Agreement.

Although the journal carries no regular page charge, for any regular published article that exceeds 12 journal pages, a mandatory $150 page fee will be added for each page in excess of 12 pages. For additional information, follow this link to Publication Charges.

Statement of Ethics and Responsibilities of Authors Submitting to AIP Journals

This journal is published as part of the charter of its publisher, the American Institute of Physics (AIP), to advance and diffuse knowledge of the science of physics and its applications to human welfare. To that end, it is essential that all who participate in producing the journal conduct themselves as authors, reviewers, editors, and publishers in accord with the highest level of professional ethics and standards.

A detailed statement of what this journal expects is available here.

By submitting a manuscript to this journal, each author implicitly confirms that it meets the highest ethical standards.

Open Access

Through participation in Author Select (Open Access Publication)^®, authors may choose open access for their published articles. By supporting both publication and archiving costs through payment of a $1500 fee, authors may instruct the journal to provide free online access to their published article, in perpetuity, to any online user. A subscription to the online journal will not be required to access full-text versions of these open access articles. See details about Author Select and look for information during manuscript submission.

Accepted Manuscripts

Authors whose manuscripts have been accepted for publication will receive correspondence informing them of the issue for which it is tentatively scheduled. Date of publication may be before the cover date of the issue. Authors of accepted manuscripts may access publication data for their manuscripts online through AIP’s AMSIS service.

Proofs and all subsequent correspondence pertaining to papers in the production process should be addressed to:

Editorial Supervisor
Chaos
American Institute of Physics
Suite 1NO1, 2 Huntington Quadrangle
Melville, NY 11747-4502, USA

Telephone: +1 516-576-2384
Fax: +1 631-396-0060
E-mail: cha@aip.org

Reference must be made to the AIP identification number (e.g., 001201CHA), title, author, and scheduled issue date. A limited number of alterations in proof are unavoidable, but the cost of making extensive alterations after the article has been typeset may be charged to the author. Please do not address correspondence about proofs, reprints, artwork, color printing charges, etc., to the Editorial Office. To do so simply delays the appropriate action and response.

Through AIP’s Accepted Manuscript Status Inquiry System (AMSIS), authors may access information about significant milestones for their accepted manuscript during the production process at AIP. AMSIS can be used only by authors of accepted manuscripts; authors will use Peer X-Press to monitor their submitted manuscript during peer review.

General information regarding publication and color charges, and similar material may be found on the inside front cover of each printed issue.

How to Prepare Your Manuscript

English Language Editing Assistance

AIP recommends Edanz for authors who wish to have the language in their manuscripts edited by a native-English-speaking language editor who is also a scientific expert. Edanz is a global editing service with offices in Japan and China. Use of an editing service is neither a requirement nor a guarantee of acceptance for publication. Please contact Edanz directly to make arrangements for editing and to receive a quotation regarding price and time.

For general format and style, consult recent issues of the journal. Link to the journal’s General Editorial Policies here.

Acceptable manuscript file types include Word, LaTeX, and PDF. PDF is acceptable for the review process only and a source Word or LaTex file is required for production. For authors who use LaTeX, REVTeX 4.1 is now available and includes style files for AIP journals and associated instructions. REVTeX 4.1 is available here.

Note for TeX users:

Please note that AIP does not compose/typeset pages in TeX. Instead we use the generic markup language XML (Extensible Markup Language). As a result, the format and layout, especially math, may look somewhat different to what was originally created in TeX.

While we appreciate the benefits to authors of preparing manuscripts in TeX, especially for math-intensive manuscripts, it is neither a cost-effective composition tool (for the volume of pages AIP currently produces) nor is it a format that can be used effectively for online publishing.

XML is critical to ensure that online content is discoverable, searchable, and accessible well into the future. It is a W3C standard that has been adopted by many publishers as well as by many software industry market leaders. Information in XML can be processed easily by computers and is both hardware and software independent. Tagged XML data is an ideal archive format as identification and extraction of specific content for reuse is relatively easy. A single XML source file is generated from authors’ TeX or Word files and feeds our entire process. All end-products and deliverables, whether print or electronic, are derived from this single XML file, reducing the chance of errors or inconsistencies.

The Manuscript, including the abstract, references, and captions, should be set up for 21.6 x 28 cm (8-1/2 x 11 in. or A4) paper with ample margins. It should be carefully proofread by the author to eliminate typographical errors and, more importantly, it is essential that the motivations, central results, and conclusion be stated in a nontechnical manner that is intelligible to a broad audience. The manuscript must be in good scientific American English; this is the author's responsibility. Number all pages in single sequence. The title page should contain the title of the article, the names of the authors, a suitable byline, and a short abstract. Parts of the manuscript should be arranged in the following order: title, author, affiliation, abstract, text, acknowledgments, appendices, and references.

The title of a paper should be as concise as possible but informative enough to facilitate information retrieval. For series publications of closely related papers, the descriptor “Part I,” or simply “I,” will not be included as part of the title of an article unless Part II has already been submitted for publication in the Journal. Part III, IV, etc., are likewise unacceptable unless the prior parts have already been accepted or have appeared in this Journal, and are properly identified in the references.

The Abstract should be self-contained (contain no footnotes). It should be adequate as an index (giving all subjects, major and minor, about which new information is given) and as a summary (giving the conclusions and all results of general interest in the article). It should be about 5% of the length of the article, but less than 500 words. The abstract should be written as one paragraph and should not contain displayed mathematical equations or tabular material.

Authors' names should preferably be written in a standard form for all publications to facilitate indexing and avoid ambiguities.

Authors with Chinese, Japanese, or Korean names may choose to have their names published in their own language alongside the English versions of their names in the author list of their publications. For Chinese, authors may use either Simplified or Traditional characters. Chinese, Japanese, or Korean characters must be included within the author list of the manuscript when submitting or resubmitting. The manuscript must be prepared using Microsoft Word or using the CJK LaTeX package. Specific guidelines for each authoring tool are given here. To ensure that we have processed the manuscript files correctly, you must proof the PDF of the manuscript as produced by the Peer X-Press system on first submission. In addition, it is essential that you check carefully any production proofs you receive prior to the publication of your paper.

The first paragraph of the article should be a Lead Paragraph and will be highlighted in the journal in boldface type. This paragraph, which essentially advertises the main points of the article, must describe in terms accessible to the nonspecialist reader the context and significance of the research problem studied and the importance of the results. The Editors will pay special attention to the clarity and accessibility of this paragraph, and in many cases may rewrite it.

Equations should be punctuated and aligned to bring out their structure and numbered on the right. Mathematical operation signs indicating continuity of the expression should be placed at the left of the second and succeeding lines. Use × rather than a centered dot, except for scalar products of vectors. The solidus (/) should be used instead of built-up fractions in running text, and in display wherever clarity would not be jeopardized. Use "exp" for complicated exponents.

Notation must be legible, clear, compact, and consistent with standard usage. All unusual symbols whose identity may not be obvious must be identified the first time they appear, and at all subsequent times when confusion might arise. Superscripts are normally set directly over subscripts; authors should note where readability or the meaning requires a special order.

References and footnotes should be in the form shown in recent issues of this journal. They should be given in a double-spaced list at the end of the text. The names, including initials, of all authors in each reference should be given (in the text, the use of et al. is permissible). For footnotes to title and bylines use a), b), c), etc. Avoid lengthy footnotes by inserting them in the text, except for the references. References within tables should be designated by lowercase Roman letter superscripts and given at the end of the table.

References to books and journal articles, listed at the end of the paper, are to be in one of these three formats:

• By number, in the order of first appearance, giving the names of the authors, the journal name, volume, year, and first page number only, as in:
  ¹⁹V. Bargmann, Proc. Natl. Acad. Sci. USA 38, 961 (1952).
  This paper will be listed as the 19th in the list of references and cited as ¹⁹.
• In alphabetical order according to the first author’s last name, giving, in addition to the name, volume, year, and first and last page, also the title of the paper cited, as in:
  Bargmann, V., “On the number of bound states in a central field of force,” Proc. Natl. Acad. Sci. USA 38, 961–966 (1952).
  This paper will be cited as “Bargmann (1952).” If there are several papers by the same author(s) and the same year, they should be distinguished by letters, as in (1952a).
• Alternatively, the alphabetically listed references (with full titles and pagination) may be numbered according to their alphabetical order and cited by their number.

Every article has to be consistent in the use of one of these three citation styles; they should not be mixed.

Separate Tables (numbered with Roman numerals in the order of appearance in the text) should be used for all but the simplest tabular material; they should have captions that make the tables intelligible without reference to the text. The structure should be clear, with simple column headings giving all units. Unaltered computer output and notation are generally unacceptable.

AUTHOR GUIDELINES FOR MULTIMEDIA SUBMISSIONS

Multimedia files can be included in the online version of published papers. These multimedia files can be viewed by simply clicking on a link in the paper, provided the reader has a video player, such as Windows Media Player^TM, QuickTime Player^TM, or RealOne Player^TM installed.

Please adhere to the following guidelines when preparing multimedia files for submission:

• When incorporating multimedia, note that the paper should be written so that the print version can be understood on its own.
• Submit all multimedia files initially with the manuscript.
• Treat all multimedia files as figures, numbered in sequence as they are referred to in text. (Multimedia files will not have a numbering scheme separate from the figures.)
• All multimedia files must be cited in the text, referred to by their figure number.
• For each multimedia file, provide a figure, which is a static representation of the multimedia file. Also provide an accompanying caption. At the end of the caption, include the phrase, "(enhanced online)."
• Video and other enhanced files should be in a format that the majority of readers can view without too much difficulty. See the multimedia guidelines here for specific submission requirements.

Supplemental Material

Supplemental files may be of two types:

• Files to aid the reviewer and not for publication.
• Supplementary information for publication alongside the manuscript.

Appropriate items for publication as supplemental material include; multimedia (e.g., movie files, audio files, 3D rendering files), data tables, and text (e.g., appendices) that are too lengthy or of too limited interest for inclusion in the article. Links (URLs) in the online (printed) journal article allow users to navigate directly to the associated files.

All supplemental material must be approved by the Journal Editor as part of a manuscript's normal review cycle, and must be listed in the reference section as follows: "See supplementary material at [URL will be inserted by AIP] for [give brief description of material]."

For additional information about depositing or retrieving supplementary material, see the Supplemental Material homepage.

Free Color Online

If authors supply usable color graphics files in time for the production process, color will appear in the online journal free of charge. A usable color graphics file must be in one of the following formats: Encapsulated PostScript (.eps), PostScript (.ps), Tagged Image File Format (.tif) and Portable Document Format (.pdf). No other type of color illustration is acceptable, and only one version of each graphics file will be accepted.

In order to maintain online color as a free service to authors, the journal cannot accept multiple versions of the same graphics file. Authors may not submit two versions of the same illustration (e.g., one for color and one for black & white). When preparing illustrations that will appear in color in the online journal and in black & white in the printed journal, authors must ensure that: (i) colors chosen will reproduce well when printed in black & white and (ii) descriptions of figures in text and captions will be sufficiently clear for both print and online versions. This is the author’s responsibility.

If usable color graphics files are received in time for the production process, authors will see color versions of those illustrations when viewing their author proofs. (The Corresponding Author will receive e-mail notification from AIP when the proof, as a PDF file, is available for downloading.) At the proof stage, authors must insert the phrase, "(Color online)," into the captions of figures that will appear in color in the online journal and in black & white in the printed journal. This is the author’s responsibility. An example of an amended figure caption appears below:

FIG. 10. (Color online) Experimental (dotted curve) and simulated (solid curve) x-ray diffraction spectra.

Although figures will appear in color online, the printed version of the article will contain black-and-white images. Therefore, a descriptive term other than a color is needed in the caption to support the data of discussion. For example, instead of “the red and blue symbols” write “the red circles and blue squares.” By adding the descriptive terms “circles” and “squares” the print reader, seeing the image in black and white, would have a clearer picture as to what is being explained in the figure.

Authors who want color figures in the printed journal must request this at the time of submission and must indicate which figures they feel have essential color. For figures for which the editors agree that the color is essential, the fees for printing the illustrations in color will be waived. Color is deemed "essential" if its use (compared to monochrome) allows the author to present a significant amount of additional, important information to the reader, or if it makes it significantly easier for the reader to interpret and understand the important information in the figure. The editors will assume that all color figures submitted without an explicit request to be printed in color are intended by the authors to be published in color in the online journal but in monochrome in the printed journal.

For all other color figures, authors or their institutions must bear the cost of any color they wish to use in the printed version of their papers. See information about color printing charges here.
