Preparing Your Data Availability Statement

In accordance with our Data Sharing Policy, all datasets supporting the conclusion of your paper need to be available to readers.

• The data should include the minimal dataset needed to interpret, replicate, and build upon your findings.
• You can either deposit your datasets in a publicly available repository (where available or appropriate) or you can present them in the manuscript.
• To inform readers of where your data can be found, all manuscripts need to contain a data availability statement.
• Based on the availability of your dataset, select the appropriate data availability statement text from the chart below and include it in your manuscript after the Acknowledgments section.

How to Cite Datasets in References: We recommend the following dataset citation format:

• Creator(s): The author names that you have listed
• Publication year: The year when the data was made publicly available
• Title: This should match the upload.
• Publisher: The name of the entity that holds and archives the dataset
• Identifier: DOIs should be displayed as linkable, permanent URLs, including the https://doi.org prefix.

Using Supplementary Material in Your Manuscript

Data tables and/or text that are too long or may be of limited interest to readers can be included as “supplementary material,” which can aid the reviewer and be accessed by readers online after publication.

If you are uploading supplementary material, please note the following:

• Please create a “Supplementary Material” section in your paper after the Conclusions. Within this section, you can provide a brief description of this information.
• Note that any mention of this information within the body of your paper should use the phrase “supplementary material,” so readers can access it.
• At initial submission, please upload your supplementary material in a pdf (SI.pdf), as it needs to be approved by the Journal Editor as part of the manuscript’s peer review process.
• We have partnered with Figshare—a general-purpose repository—to host all supplementary material.
  • After your manuscript has been accepted for publication, AIP Publishing will deposit your supplementary material in Figshare on your behalf, where it will be assigned a digital object identifier (DOI) for citation and referencing.
  • This increases the discoverability of your materials due to the searchable, user-friendly Figshare platform, which contains analytics and usage data to note the impact and influence of your work.
  • This simple process helps you share your supplementary material more broadly without additional effort.

References

Numerical references are required. Include the citation to the dataset(s) in the References list of your manuscript, providing the following required elements: Creator(s), Title, Publisher, Publication Year, and Identifier and may contain these optional elements: Version and Resource Type.

• In the References list: Numbering references according to the cited order.
• In the text: Citing references by their number in the upper right corner of the corresponding positions.

Formatting

• Variables should be in italic. Their subscripts or superscripts, if they are also variables, should be italicized. However, if the subscripts or superscripts are not variables, they should not be italicized.
• Vectors and matrices should be both bold and italic.
• Variables in figures, tables, and equations should be formatted in italic, the same as in the text.
• Displayed equations should be punctuated (period or comma), aligned to bring out their structure, and numbered on the right-hand side.
• Indentation after equations is dependent on whether an author has started a new paragraph after an equation (indent), or if the text following the equation is part of the same paragraph (no indent).
• Identify all figure parts with (a), (b), etc. Avoid any large size differences of the lettering and labels used within one illustration.

JCP Communications

These are preliminary reports of highly significant work whose rapid publication will be important to a relatively large number of workers in the field.

• Communications may be complete in themselves or may be followed by Articles, which present substantial additional significant information.
• Communications have a length limit of 3500 words. Note that figures, equations, tables, and references should not be included in the 3500-word count.
• Because of the length limitation, the standard of proof required to support the scientific argument is relaxed somewhat. Scientific arguments that are plausible and, if correct, important, may be presented in Communications even if the detailed proof needs to be presented in a later publication.
• Arguments that are implausible but can be demonstrated by lengthy and detailed proof to be correct should not be presented in Communications.
• Communications are given priority attention in both the peer review and production processes.

Reports of new potential energy surfaces in JCP

All papers on new potential energy surfaces need to be accompanied by a tape archive (e.g., PES.tar) file.

• The PES.tar (tape archive file) should contain a computer program that can be used to generate the potential and preferably also its forces for use in classical trajectory calculations.
• The only exception will be potentials that are simple enough to be reconstructed based only from the information given in the paper.
• The computer program can be written in any modern computer language, but the compiler that the authors used (including its version number) needs to be specified, and the program needs to be accompanied by example input and output files that reproduce some of the key results presented in the paper.
• The PES.tar file will be made available to the referees to give them the option to examine it.
• If the manuscript is accepted for publication, the PES.tar file will be published as supplementary material.

TeX Submission Template

Authors are encouraged to use the JMP-specific TeX template in Overleaf to prepare their submission.

Uncertainties

The objective of JPCRD is to provide critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation. Such data are of little use without a quantitative characterization of uncertainties that includes effects of both random (precision) and systemic (bias) uncertainties, as well as a discussion of sources of errors and the rationale for assigning uncertainty estimates. For a more detailed discussion of uncertainty analysis, we refer authors to the following resources:

• U.S. Guide to the Expression of Uncertainty in Measurement, ANSI/NCSL Z540-2-1997, American National Standard for Expressing Uncertainty (National Conference of Standards Laboratories, Boulder, CO, 1997).
• B. N. Taylor and C. E. Kuyatt, Guidelines for Evaluating and Expressing the Uncertainty of NIST Measurement Results, NIST Technical Note 1297 (NIST, Gaithersburg, MD, 1994).

References

The use of et al. is permitted in the reference list. Do not insert “and” before the final author’s name or a comma before “et al.” [²¹A. Cavalleri, S. Wall, C. Simpson et al., Nature (London) 442, 664 (2006).]

• Please note that including article titles in the reference list is optional but encouraged.

Units, symbol, terminology, and chemical nomenclature

It is the policy of JPCRD to follow the recommendations of recognized internationals bodies such as ISO, IUPAC, and IUPAP unless there are strong grounds for making an exception. Sources of recommendations on symbols, terminology, and units are the following:

• Quantities and Units, ISO Standards Handbook, 3rd ed. (International Organization for Standardization, Geneva, Switzerland, 1993).
• Quantities, Units and Symbols in Physical Chemistry (the Green Book), 3rd ed. (IUPAC, RSC Publishing, Cambridge, 2007).
• Symbols, Units and Nomenclature in Physics, IUPAP Document IUPAP 25, 1985. [Reproduced in Physica A 146, 1 (1987)].
• A. Thompson and B. N. Taylor, Guide for the Use of the International System of Units (SI), NIST Special Pub. 811, 2008 edition (NIST, Gaithersburg, MD, 2008).

The International System of Units (SI) should always be used unless the Editor has granted an exception. The nomenclature practices of Chemical Abstracts, or those based on IUPAC recommendations, should be followed. If you are preparing compound indices for your paper, please consult the current CA Index Guide. It is desirable to include CAS Registry Numbers in papers that give data for multiple chemical compounds.
Please follow the conventions for using roman and italic fonts. Roman (non-italic) font is always used for chemical formulas, units, numbers, mathematical constants, and operators (∏ and ln), and descriptive terms. Italic font is used to denote variables, physical quantities, and functions.
The following are some examples of correct usage:
T_min = 273 K (italicize physical quantity temperature and not descriptive “min” or “K”)

(Do not italicize operator “exp” or subscript “B” for Boltzmann.)
Avoid the ambiguous term “log”; natural logarithms should be written “ln” (preferred) or “log_e” while base-10 logarithms should be written “lg” or “log₁₀”. Please use a minus sign (−) rather than a hyphen (-) to denote negative numbers or subtraction. Superscripts or subscripts should be formatted through the font group rather than raising or lowering individual characters.

List of symbols

A list of symbols is optional. It is recommended to use a list of symbols if the paper contains many symbols, whose meaning is not obvious, especially if the paper is relatively long. Otherwise, symbols should be defined when they first appear in text.

Headings and subheadings

Headings and subheadings in the text should have a maximum of four levels and should be numbered as follows:

• 1. (Main level)
• 1.1. (Second Level)
• 1.1.1. (Third level)
• 1.1.1.1. (Fourth level)

The first level is normally “1. Introduction” and the last is “References.” Please refer to the sections in text as “Sec. 1.1”, etc., except at the beginning of a sentence where “Section 1.1” should be used.

Preparing Your Graphics

When possible, authors are encouraged to adjust their figures for the black and white hard copy version of the journal. For example, using different symbols (i.e., circles, squares, etc.) or different types of lines (i.e., dashed lines, dotted lines, etc.) is useful to those who are viewing the figure in black and white instead of color. Please see the “Color Printing Charges” section of the author guidelines for additional information on preparing graphics suitable for the print journal.

Nomenclature

Authors are asked to comply with the official nomenclature and symbols of the Society of Rheology: https://pubs.aip.org/sor/jor/pages/nomenclature

Formatting

• Special characters such as “μ” in “μm” and “μs” should not be italicized.
• Variables should be in italic. Their subscripts or superscripts, if they are also variables, should be italicized. For example, with “T_i, i=1,2,3…,” then “i” should be in italic. However, if the subscripts or superscripts are not variables, they should not be italicized. For example, if defining the temperature of a door and window as “T_d” and “T_w” then “d” and “w” should not be italicized.
• The natural logarithm base “e”, imaginary unit “I”, and pi “π” (when it equals 3.14159…) should not be bold or italic.
• Vectors and matrices should be both bold and italic.
• Points should be in italic, such as O(x,y), P(m,n), while the comma and parentheses should not be italicized.
• Variables in figures and tables should be formatted the same as in the text.
• For phrases in figures and tables, only the initial letter of the first word should be capitalized.
• There should be a space between a number and unit.
• Identify all figure parts with (a), (b), etc. Avoid any large size differences of the lettering and labels used within one illustration.

No Cover Letter for Physics of Fluids Submissions

Cover letters are not accepted with submissions for Physics of Fluids. The Editor-in-Chief wants to save authors the time of writing cover letters and Associate Editors the time of reviewing them. Any submission with a cover letter will not be considered.

Response Letter Required for Revisions

When submitting a revised manuscript, authors must include a response letter detailing how they addressed the reviewers’ feedback in the new version of the manuscript.

Letters

The purpose of the Letters section is to provide rapid publication of important and time-sensitive new results in the fields regularly covered by Physics of Fluids, in the form of a condensed communication.

• Results of extended research should not be presented as a series of Letters in place of comprehensive articles.
• Except for length, Letters manuscripts have the same criteria as longer articles. However, there is usually a three-month time limit, from date of receipt to acceptance, for processing Letters manuscripts. Timeliness, current importance of the subject matter, brevity, and clarity of presentation determine the acceptability of contributions.
• Feasibility studies and proposals for future research are not appropriate for the Letters section and will rarely be accepted.
• Each Letter should be self-contained and may, on occasion, be followed by a comprehensive article in Physics of Fluids or elsewhere.
• Letters are limited to seven (7) printed pages in length, including space for title, figures, tables, references, and the abstract limited to 100 words; Letters do not have section headings.

Please use these guidelines for estimating length of POF Letters.

• POP Editorial Summary Form – Tutorials

The editors will review your proposal and provide feedback on its suitability for Physics of Plasmas. Editor comments will help you write your paper with the best chance of positive review and fast publication.

If you have already written a paper, please submit it directly at http://pop.peerx-press.org without completing a Summary Form. Instructions for preparing Perspectives and Tutorials are given below.

Preparing your Perspective Manuscript for Physics of Plasmas

Perspectives are articles on focused topics of current interest in plasma physics research.

• Editors commission recognized experts in the field to write these articles.
• Authors writing a perspective article provide an objective and balanced overview of recent advances within the field and, importantly, provide their unique views on where the field is headed and promising strategies for progress.
• Perspectives are not Review articles.
• Perspectives may be submitted by a single author or from multiple co-authors.
• All Perspectives are subject to peer review. An invitation from the editors does not guarantee acceptance.

When preparing your Perspective manuscript, please consider the following general guidelines:

• Recommended length in print: We suggest 5–10 pages, although longer articles are also appropriate.
• Title: Use a short descriptive title to attract readers’ attention.
• Figures: There is no limit to the number of figures that can be included in the article.
• Video/multimedia: Including these in your manuscript is encouraged.
• Number of references: There is no limit to the number of references that can be included in the article.
• Permissions: If you are reusing material from previously published work, please be sure to obtain the proper permissions for publication. We recommend that you request permissions as soon as possible to avoid publication delays. For more information on permissions, please see https://publishing.aip.org/authors/author-permission-faq.
• While no specific format is required for Perspective articles, we recommend that you include:
  • A brief, concise assessment of the status of the field: This assessment should focus on the last 3–5 years of research and can be written either in a brief overview or by presenting new, unpublished results from the author’s own research. Please note: Extensive reviews of the field are not appropriate for a Perspective article, and brief overviews should constitute no more than 50 percent of the total article.
  • A unique, forward look at where the field is headed: Perspectives are characterized by the personal views and opinions of the author (or authors) as an expert in the field. Authors are encouraged to focus on newly implemented innovations and their broad-ranging implications for the area of study, identify open questions that need to be addressed, and propose or support new hypotheses.

Preparing your Tutorial Manuscript for Physics of Plasmas

Tutorials are graduate-level educational tools used to help shape the new generation of researchers in plasma physics. They also support researchers who are interested in improving their knowledge of and skills in particular areas.

• Tutorials do not have to provide original research content.
• They should explain the principles and techniques in a particular research area with an educational perspective.
• They need to convey a broad overview of the objectives, results, and open question for that area.
• Tutorials may be as short as 3–5 printed pages or as long as 10–15 printed pages.
• They are screen by the Editor-in-Chief, assisted by the Associate Editor.
• Once a Tutorial manuscript is accepted, it will go through the same peer review process and needs to meet the same high standards as regularly published papers.

Considering the purpose of a Tutorial, referees will write their reviews on the following points:

1. Is the Tutorial aimed at the appropriate level for the Physics of Plasmas readership?
2. Is the research area covered with enough depth and broad perspective (for extended Tutorials)? Can the presentation be improved?
3. Is the topic of the Tutorial timely?
4. Does the reference list appear to be appropriate? Are the references too one-dimensional, i.e., directed toward the author’s own research or research at the author’s institution? Do the references provide adequate background references to allow readers to put the work in context with previous and current work?
5. Is the Tutorial written in clear English, so editors, reviewers, and readers can fully understand it?
