Physics paper framing

This skill is the canon for the external and bookend framing of a physics paper—theoretical, analytical, computational, or experimental. It covers Stages 3, 6, 7 (bookend alignment), and 8 of physics-paper-workflow.

Every framing component is a projection of physics-paper-claims tailored to a specific reader and stage of reading. Detailed sentence and passage language rules live in physics-language-principles.

1. Standard abstract

For most physics journals (Physical Review Letters, PRX, PRX Quantum, PRA, PRB, Quantum, New Journal of Physics, etc.), the abstract is a few-sentence presentation of the paper's top ~3 claims—the elevator pitch written in precise, technical, and modest language.

• Structure of a standard abstract:
  1. Reason for doing the work (1–2 sentences): The physical context, what existing approaches do, and the open problem or limitation that motivates the paper.
  2. What this work constructs, derives, or demonstrates (1–2 sentences): The core concept, method, framework, or system introduced here ("Here we…").
  3. Crucial figures of merit (1–3 sentences): Specific quantitative or structural benchmarks that make the claims concrete (not "it worked," but "it worked for 9 hours on a single AA battery"—or the exact accuracy deviation, scaling exponent, or optimization gain under stated conditions).
  4. Payoff (0–1 sentence): Why a reader should spend their time reading the paper, without trying to fit the entire outlook or discussion section into the abstract.
• Hard constraints:
  • Know the exact word or character limit of the target journal before writing (e.g., PRL $\le 600$ characters; Physical Review journals $\lesssim 5%$ of article length and $<500$ words).
  • Self-contained vocabulary: Define an acronym in the abstract only if the abstract itself uses it again; use field-standard terms rather than internal shorthand that requires the body text to decode (names-and-symbols.md).
  • Traceable numbers: Every number quoted in the abstract must match a specific section, table, or data key in the body, with its model or regime stated where needed for accuracy. Detect: (1) count words/characters against the target venue's limit; (2) check that each of the top ~3 claims and at least one concrete figure of merit or exact condition appear explicitly (never a vague promise like "We discuss its implications"); (3) flag any acronym or symbol defined in the abstract that is used fewer than twice in the abstract itself.

2. Nature-style summary paragraph (the exception)

Nature-family journals use an embedded abstract (summary paragraph) as the opening paragraph of the main text. Write it side-by-side with the journal's annotated guide (~190–250 words, maximum 300 words):

Move	Sentences	Audience & job
1. Basic introduction	1–2	Comprehensible to a scientist in any discipline
2. Detailed background	2–3	Comprehensible to scientists in related disciplines
3. General problem	1	Clearly states the specific gap or question addressed by this study ("However, …")
4. Main result	1	Summarizes the headline result, opening with "Here we show…" or its direct equivalent
5. Direct comparison	2–3	Explains what the main result reveals in direct comparison to what was thought previously, or how it adds to prior knowledge (with figures of merit)
6. General context & perspective	1–2 (+ optional 2–3)	Puts the results into a general context; optionally adds 2–3 sentences of broader perspective comprehensible across disciplines

• Non-redundancy with the body opening: Because the summary paragraph is the first paragraph of the article, the second paragraph must not repeat the same funnel from scratch; step directly into the technical setting or the next layer of the argument. Detect: label every sentence of the summary paragraph with Move 1–6 and check total word count ($\le 300$ words); then compare paragraph 2 of the manuscript against Moves 1–3 to ensure paragraph 2 advances directly into the technical argument rather than restarting the broad introduction.

3. Revising and Introduction ↔ Conclusion alignment

If the paper was built following physics-paper-workflow (claims → figures → abstract → outline → draft), you rarely have to scrap the body, but you will redo the introductory 3–4 paragraphs and the conclusion/discussion a few times. It is always better to do this among co-authors than with a referee in the loop.

• The Conclusion → Introduction back-propagation rule: By the time you finish drafting the paper and write the conclusion, you have often discovered a clearer, sharper, or more accurate way to state the claims than when you began.
  • Compare how the Conclusion/Discussion states the findings against the Introduction, the Abstract, and the claims list (Sections/claims.tex or manuscript plan).
  • If the Conclusion states the point more clearly, revise the Introduction, Abstract, and claims list to match it.
• Promise vs. delivery:
  • Every question posed in the Introduction must be answered in the body and closed in the Discussion/Conclusion.
  • No claim in the Title, Abstract, or Introduction may overstep the conditions, approximations, or scope established in the body and Discussion (narrative.md, limits). Detect: place the Abstract, Introduction ¶4 ("In this work, we show..."), and Conclusion side by side. Flag any claim that is sharper or more accurate in the Conclusion than in the Introduction/Abstract, any question raised in the Introduction that is not answered in the Conclusion, or any scope limitation stated in the Discussion that is missing from an unqualified claim in the Abstract/Introduction.

4. Authorship and acknowledgments

• Focus on a timeless paper: Do not get hung up on which journal the paper "has" to go to; an important and timeless paper will remain so independent of where it appears.
• Settle authorship early and explicitly:
  • Discuss between the lead authors and the PI who should be included in the author list versus the acknowledgments, and why.
  • Confirm with each co-author their understanding of contributions and expectations.
  • Finalize the author list before circulating the manuscript for broader comments (if a draft must circulate before the list is final, use obvious placeholders rather than an unconfirmed ordering).

5. Cover letter and submission package

Write the cover letter last, once the claims, abstract, and manuscript text are locked.

• Start from the list of claims: Translate physics-paper-claims into even plainer and less specialized language aimed at a journal editor who handles a broad portfolio:
  1. What the paper does and its headline claims (without heavy notation or sub-field jargon).
  2. Why these results advance the boundary of knowledge and what they enable next.
  3. Why the scope, generality, or timeliness of the work fits this journal's readership.
• Submission completeness:
  • Verify exact funding agency names and grant numbers with the PI and administrators.
  • Include all required conflict-of-interest and author-contribution declarations.
  • Include a clear Data and code availability statement pointing to the repository that reproduces the paper's figures, tables, and quoted numbers. Detect: compare the cover letter against the Abstract; if sentences are pasted verbatim from the Abstract or contain unexplained subfield notation/macros, rewrite from the claims list in plain scientific prose.

Anti-patterns

Anti-pattern	Shape instead
Abstract says "We study X and discuss its implications" without stating the result or figure of merit	State what you found and the specific number, bound, or condition that demonstrates it
Abstract tries to summarize every subsection and the full future outlook	Focus on the reason for the work, the top ~3 claims, and the key figures of merit
Nature article whose second paragraph repeats the opening summary paragraph's background funnel	Treat the Nature summary paragraph as paragraph 1 and advance directly in paragraph 2
Conclusion has a much sharper formulation of the central insight than the Introduction	Back-propagate the clearer formulation from the Conclusion into the Introduction and Abstract
Cover letter pastes the abstract verbatim or uses dense manuscript notation	Rewrite from the claims list in plain, unspecialized language for a broad-portfolio editor
