prl-scope-fit

name	prl-scope-fit
description	Use when deciding whether a physics result clears Physical Review Letters' importance-and-broad-interest gate, or whether it belongs in Physical Review A–E / PR Research. Diagnoses venue fit; does not write or frame the result.

PRL Scope Fit (prl-scope-fit)

When to trigger

• You suspect the result is solid but may be "incremental" or "specialist"
• You cannot articulate why a physicist outside your subfield should care
• A coauthor asks "PRL or Phys. Rev. B?"
• An editor has previously bounced similar work on importance/breadth grounds
• Before investing in figures and prose, you want a go / no-go on venue

The two-part gate (both must pass)

PRL publishes Letters across all of physics — condensed matter, AMO, particle/nuclear, gravitation/astro, statistical/soft, quantum information, and more. The gate is two tests, AND-ed:

1. Importance — Does the result substantially advance its field? A genuinely new effect, a decisive measurement, a qualitative resolution of an open problem, a method that unlocks previously inaccessible regimes.
2. Broad interest — Would physicists outside the immediate subfield want to know this? A result is broad if it changes how a neighboring community thinks, transfers a technique, or settles a question of general physical principle.

A correct, careful, but incremental result can pass rigor and still fail the gate. That is the most common PRL rejection mode and it is not a quality judgment — it is a venue judgment.

Decision table

Situation	Verdict
New phenomenon / qualitative surprise + clear cross-subfield relevance	PRL — strong fit
Decisive measurement settling an open, widely-discussed question	PRL — strong fit
Method enabling a regime others could not reach, with general appeal	PRL — fit (frame the breadth)
Solid result, narrow audience, "next step" in an established program	Phys. Rev. A–E (subfield match)
Thorough archival study, full parameter sweeps, specialist detail	Phys. Rev. B/D/E / PR Research
Sound but inconclusive / preliminary; needs more data	PR Research or hold
Confirmation of an expected result with no new principle	Specialized PR journal

How to stress-test the gate

• The neighbor test: name a specific physicist in a different subfield and state, in one sentence, why they would read this. If you cannot, broad interest is weak.
• The headline test: write the result as a one-line APS Physics highlight. If the headline is "we measured X more precisely," importance is likely incremental.
• The displacement test: what prior belief does this overturn, sharpen, or unlock? "Nothing, it extends" → specialist.
• The self-citation test: if the natural citing audience is only your own group and two others, breadth is narrow.

Checklist

• The single most important claim is stated in one sentence
• Importance is articulated (new effect / decisive measurement / unlocked regime), not just "novel"
• Broad interest is named for a concrete out-of-subfield audience
• You can name the prior belief the result changes
• You have honestly considered whether PR A–E / PR Research is the better venue
• If borderline, you have a breadth argument ready for the cover letter

Anti-patterns

• Equating novel with important — PRL rewards significance, not mere first-ness
• Claiming broad interest by listing applications that do not follow from the result
• Submitting a "letterized" version of a long specialist paper to dodge the breadth gate
• Ignoring that editors can decline a correct Letter purely on importance/breadth

Output format

【Central claim】one sentence
【Importance】new effect / decisive measurement / unlocked regime / resolves open question
【Broad interest】named out-of-subfield audience + why they care
【Prior belief changed】...
【Verdict】PRL strong / PRL with breadth framing / retarget to PR A–E / PR Research
【Next】prl-results-framing (if PRL) or retarget venue
