How statement and proof provenance work
The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.
- Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
- AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
- AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.
These labels describe origin, not correctness: citations and verification chips remain separate evidence.
Matter energy survives zero instantaneous polarization
A single allowed oscillator state in the undamped Lorentz model. It illustrates the model's positive kinetic material-energy term when the instantaneous polarization vanishes; it reports no experiment and makes no claim beyond the stated constitutive model.
Statement
In the one-oscillator Lorentz model, take an undamped oscillator with in F m s and in s. At a time , compare two allowed states with the same instantaneous fields , , , polarization , and therefore displacement : in the first state set , and in the second set for any fixed nonzero real vector in A m. The second state has oscillator energy density in J m, while the first has zero oscillator energy. Thus the instantaneous pair alone does not determine the full stored energy in this dispersive model.

Facts & Assumptions
Given: Countable Choice, one undamped Lorentz oscillator with , ; its state at consists of and ; take and at that instant.
The adopted oscillator model permits the initial polarization and polarization-velocity state and uses (Finite Lorentz oscillator closure).
For this undamped Lorentz state, the material energy density is , added to the positive electromagnetic field energy (Augmented energy and passive absorption, Lorentz branch).
The Euclidean squared norm is positive for every nonzero vector: when (The Euclidean inner product on ).
Countable Choice is an explicit hypothesis of the finite-energy oscillator theorem used here (The Axiom of Countable Choice (), Augmented energy and passive absorption).
Verification
In the first state , so [F1] gives zero oscillator energy. In the second state , so [F1] gives by [F2] and . Both states have and , hence the same , and both have ; they therefore have identical instantaneous data but different total stored energies.
The comparison is between allowed model states at one time; it is not an observed outcome or a claim about microscopic material energy. Hence the full oscillator energy is not a function of the instantaneous pair alone.
