v0.1.0: initial release

First release of absnoise: Andreev-bound-state occupation noise and detector budgets for proximity Josephson junctions, distilled as the general-purpose engine of the accompanying manuscript (T. M. Mahim, A. S. M. Mohsin and M. M. Rahman, "Andreev occupation noise sets the sensitivity limit of proximity Josephson thermal detectors").

Implemented and tested: exact finite-length ABS solver with continuum free energy; BCS gap solved from the gap equation (no data file); closed-form short-junction ensemble with occupation sums and the Cauchy-Schwarz temperature-resolution bound; level-resolved finite-length sums; four-state pair-process master equation; telegraph Monte Carlo; device budgets (temperature resolution, resonator frequency noise, matched-filter energy resolution); six cited graphene junction recipes (Jung et al., Phys. Rev. Applied 26, 014078 (2026), arXiv:2503.06850) and graphene thermodynamics (Lee et al., Nature 586, 42 (2020)).

28 analytic tests, each anchoring a closed form: short-junction and Kulik levels, the ballistic Ic anchor, both BCS asymptotes and the u(0.5) midpoint, exact bound saturation for uniform transparency and non-violation at finite length, master-equation limits and sum rules, Monte Carlo Lorentzian and variance convention, and the exact frequency-noise knee.
