How to Cite in AIP Style: Physics Research Guide

This guide will help you understand how to properly cite sources in AIP format, the standard citation format for physics journals and American Institute of Physics publications, ensuring that your academic work meets the necessary standards for the field.

What is the AIP Citation Format?

AIP style is the citation format developed by the American Institute of Physics, used across physics journals, conference proceedings, and research publications. As the dominant citation system in physics, understanding AIP style is essential for anyone publishing in journals like Physical Review, Applied Physics Letters, or Journal of Applied Physics.

The AIP Style Guide (4th Edition) establishes the core rules, though many physics writers use LaTeX with BibTeX to handle citation formatting automatically. If you're writing in Word or need to format citations manually, this guide covers everything you need.

Quick Overview: AIP Citation Format

AIP uses a numbered citation system where references are numbered in the order they first appear in your text. The same number is used for all subsequent citations of the same source. Key characteristics include:

Superscript or bracketed numbers for in-text citations
Journal titles abbreviated per ISO 4 standards
Article titles typically omitted (though some journals include them)
Volume numbers in bold
Year in parentheses at the end

In-Text Citations in AIP

AIP offers two options for marking citations within your text. Choose one and use it consistently:

Superscript Numbers

The quantum Hall effect demonstrates remarkable precision in resistance measurements.¹ These calculations agree with previous studies.²

For multiple citations: ...as shown in prior work.¹,² or ...established by several groups.³⁻⁵

Author Name with Superscript

As demonstrated by Roberts,² these calculations confirm the theoretical predictions. The original framework was established by Feynman.¹

When citing the same source multiple times, always use the original reference number—don't assign a new number.

Reference List Format

Journal Articles

The standard format excludes article titles:

With optional issue number:

For four or more authors, use "et al." after the first author:

Books

Include publisher, location, year, and page numbers as applicable:

For edited volumes:

Conference Papers

Websites

The AIP Style Manual doesn't provide detailed guidance for web sources, but the following format is commonly accepted:

Preprints (arXiv)

Datasets

AIP Journal Abbreviations

Physics journals follow ISO 4 abbreviation standards. Common examples:

Full Journal Name	AIP Abbreviation
Physical Review Letters	Phys. Rev. Lett.
Applied Physics Letters	Appl. Phys. Lett.
Journal of Applied Physics	J. Appl. Phys.
Physical Review A/B/C/D/E	Phys. Rev. A/B/C/D/E
Nature Physics	Nat. Phys.
Science	Science
Reviews of Modern Physics	Rev. Mod. Phys.

For a comprehensive list, consult Appendix G of the AIP Style Manual or the CASSI database.

Common AIP Mistakes to Avoid

Including article titles unnecessarily: Most AIP journals omit article titles from references. Check your target journal's specific requirements.
Forgetting bold volume numbers: Volume numbers should be in bold or set off clearly from issue numbers.
Incorrect author formatting: Use initials before surnames (J. Smith, not Smith J.).
Wrong journal abbreviations: Always verify abbreviations—using incorrect forms is a common rejection reason.
Inconsistent citation numbering: If you cite source [3] again later, use [3] again—don't create a new reference entry.

AIP Citation Tools

For physics writing, LaTeX with BibTeX is the standard approach. Overleaf provides AIP journal templates with preconfigured citation styles.

Reference managers like Zotero include AIP style sheets. When using these tools, always verify the output against your target journal's requirements.

Frequently asked questions

Should I include DOIs in AIP references?

It depends on the specific journal. Some AIP journals now require or encourage DOIs, while others follow the traditional format without them. Check your target journal's author guidelines. When included, DOIs typically appear at the end of the reference as a URL: https://doi.org/10.1103/PhysRevLett.105.136805

What's the difference between AIP and APS style?

The American Physical Society (APS) uses the AIP citation format but has its own style guide for other manuscript elements. For citations specifically, they're essentially identical. However, APS journals may have specific formatting requirements for other elements, so always consult the specific journal's author guidelines.

Can I use footnotes for citations in AIP style?

No, AIP style uses a separate reference list, not footnotes. Footnotes in AIP-style papers are reserved for additional comments or clarifications, not for citations. Keep your references in a numbered list at the end of your manuscript.

How do I cite unpublished work or private communications?

Private communications are typically cited in-text only, not in the reference list: “...as suggested by J. Smith (private communication).” For work submitted but not yet published, use “(to be published)” or “(submitted)” with as much information as available.

How do I handle references with many authors?

For four or more authors, list only the first author followed by “et al.” Some journals allow listing up to three authors before using “et al.” Check your target journal's policy to be certain.
