research-note · a record framework
The agent computes and writes the record. You read it and decide.
01
A paper reports the one tunnel that reached gold. A record keeps them all.
02
It runs, watches, collects, concludes — then stops one step short.
### Entry: 3×3 TFIM ground-state scan
- Id: 01.002
- Status: closed
- Motivation: how does energy error change with D?
- Recipe: open TFIM; dt=0.05; second order
D in {2, 4, 8}; QuSpin ED reference
- Facts: D=2 6.77e-4
D=4 1.34e-4
D=8 1.51e-4
- Conclusion: fivefold gain at D=4,
then a shallow plateau
## Goal
Compare Quimb simple update with QuSpin ED.
## Plan
- [x] P1 - do both codes use the same model?
01.001 convention gate - passed
- [x] P2 - does the error shrink with D?
01.002 ground-state scan - closed
## Verdict
The scan improves from D=2 to D=4, then
becomes non-monotonic at D=8. This recipe
supports an error floor near 1.5e-4.
These numbers come from the included 3×3 TFIM example, which records both the ground-state comparison and real-time dynamics.
03
Validated code can move into the project library, and reviewed conclusions into the wiki. The original record stays intact.
04
Question, procedure, evidence, verdict — and a person's acceptance of it.
Each reviewed calculation adds a judgment the next investigation can build on.
A reviewed entry is finished work — hand it over, cite it, or train on it.
