Single-Prime Thermal State
Abstract
The single-prime thermal spectrum is a normalized geometric occupation law.
Definition 1.1 (Single-prime thermal spectrum).
Lean statement: D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalState
Formalization. D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalState (✓ std3).
Source. Repository-derived.
Commentary.
The countable diagonal model is represented by the occupation-number spectrum (1 - p^(-s)) p^(-s k) at mode k.
Definition 1.2 (PMF associated with the thermal spectrum).
Lean statement: D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalPMF
Formalization. D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalPMF (✓ std3).
Source. Repository-derived.
Commentary.
In the regime p > 1 and s > 0, the spectrum is packaged as a countable probability mass function.
Theorem 1.3 (Thermal spectral weights are nonnegative).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalState_nonneg (✓ std3). ∎
Source. Repository-derived.
Commentary.
For p > 1 and s > 0, the ratio p^(-s) lies in (0, 1). Both factors in each diagonal weight are therefore nonnegative.
Theorem 1.4 (Thermal spectral weights are normalized).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalState_tsum_eq_one (✓ std3). ∎
Source. Repository-derived.
Commentary.
The geometric series with ratio p^(-s) sums to the inverse prefactor, so the diagonal spectrum has total mass one.
Theorem 1.5 (The zero occupation slot).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalState_zero_slot (✓ std3). ∎
Source. Repository-derived.
Commentary.
At k = 0 the geometric power is one, leaving exactly the vacuum weight 1 - p^(-s).
Theorem 1.6 (The PMF realizes the thermal spectrum).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalPMF_apply (✓ std3). ∎
Source. Repository-derived.
Commentary.
Taking the real mass of the named PMF recovers the corresponding diagonal spectral weight at every occupation number.
Theorem 1.7 (The PMF is geometric in the ratio parameter).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalPMF_is_geometric (✓ std3). ∎
Source. Repository-derived.
Commentary.
The PMF has geometric ratio p^(-s), with success prefactor 1 - p^(-s), pointwise on the countable occupation space.
Theorem 1.8 (Closed entropy of one thermal mode).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermal_entropy_eq (✓ std3). ∎
Source. Repository-derived.
Commentary.
The reusable geometric Gibbs entropy theorem gives the closed Shannon formula for this diagonal mode; only p > 1 and s > 0 are needed.
Theorem 1.9 (Modal thermal entropy adds over primes).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.modal_thermal_entropy_additive (✓ std3). ∎
Source. Repository-derived.
Commentary.
For s > 1, the existing zeta diagonal PMF entropy equals the tsum of the named single-prime thermal mode entropies.
Theorem 1.10 (Base greater than one is necessary).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.base_gt_one_is_necessary (✓ std3). ∎
Source. Repository-derived.
Commentary.
At the concrete base p = 1 and s = 1, every prefactor is zero and normalization fails.
Theorem 1.11 (Positive temperature is necessary).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.positive_temperature_is_necessary (✓ std3). ∎
Source. Repository-derived.
Commentary.
At the concrete base p = 2 and temperature s = 0, the ratio is one, all weights vanish, and the total is not one.
Theorem 1.12 (A negative-temperature spectrum is not summable).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.negative_temperature_not_summable (✓ std3). ∎
Source. Repository-derived.
Commentary.
At p = 2 and s = -1, the weights are -2^k, giving a concrete non-summable divergent boundary case.
Theorem 1.13 (Infinite temperature leaves the vacuum spectrum).
Proof. Machine-checked in Lean as D5/S3/Quantum/CountableSlices/SinglePrimeThermalState.singlePrimeThermalState_tendsto_infinite_temperature (✓ std3). ∎
Source. Repository-derived.
Commentary.
For a fixed occupation number and p > 1, the spectrum tends as s tends to infinity to one at k = 0 and zero at every k > 0.
