QMBL: the Quantum Many-Body Leaderboard. The best published ground-state energies for lattice models, hydrogen chains and the electron gas, with a JSON API and an MCP server for agents.
README.md
A live record of SOTA published ground-state energies for lattice models, hydrogen chains and the electron gas.
Organised literature for fellow researchers and AI systems. So that we can see the works of the wider research community at one glance, build on each other's work more efficiently and advance frontier science together.
AI agents and crawlers: read qmbl.org/llms.txt for what the data means and where it is, and the JSON API under qmbl.org/api/.
Use QMBL with your agent
Paste this prompt into your favorite agent:
Use QMBL: the Quantum Many-Body Leaderboard (qmbl.org) to answer my questions about ground-state energies. First read https://qmbl.org/llms.txt. Then use the JSON API it describes: https://qmbl.org/api/models.json lists the models, https://qmbl.org/api/m/<model>.json gives every instance of one model with its exact and best energies, and https://qmbl.org/api/i/<instance_id>.json gives every published energy of one instance.Or add the MCP server. Paste this prompt into your favorite agent:
Add the QMBL MCP server: download https://raw.githubusercontent.com/quantum-many-body-leaderboard/quantum-many-body-leaderboard/main/mcp/server.mjs and register it as a local stdio MCP server named "qmbl" that runs `node <path to server.mjs>`.

Details
Every row has a bound_type that says what kind of number the energy is
(RULES.md §4).
Bold marks the record. RULES.md §6 says how it is chosen.
○ marks a row where no error bar and no energy variance was found in the source.
† marks a sampled energy with a variance but no error bar. Both rows stay in rank
order. Error metrics defines the markers.
The code column links the code that produced a result, where its authors published it: the
place to start when you want to rerun it. For a row QMBL computed, "rerun (QMBL code)" links the
command, the commit and the package versions it ran with. Where the authors published no code
of their own, a muted "uses …" names the library they used, if their paper says. An empty
cell means that no source read so far names the code or a library.
How the links were found.
Rules: RULES.md. Units, conventions, error metrics, provenance and defects:

Contributing
To add an energy, use the new result form.
To add an instance QMBL does not have yet, a lattice model or an electron-gas cell, use the
new instance form.
To correct a row or comment on it, click the pencil at the end of the row on
qmbl.org/instances; it opens the
about-a-row form with the row filled in. Be specific and technical
(RULES.md §10). A sampled energy without an
error bar is marked †. Send the error bar so the row can be compared with its
neighbours.
CONTRIBUTING.md gives the details: what happens after you submit, how
to change the code, and how AI systems submit.
