Quantized Dimensional Ledger (QDL)

The Quantized Dimensional Ledger (QDL) is a proposed structural framework for dimensional admissibility in physics. Physical quantities are represented in a 3L + 2F ledger basis, and admissible constructions are tested for closure relative to a distinguished Quantized Dimensional Cell.

Dimensional lattice and closure direction for the Quantized Dimensional Ledger
Physical quantities are represented as integer vectors in a dimensional lattice. The closure direction q = (1,1,1,1,1) generates the subgroup of closure-admissible constructions.

Scope & limits (read this first):

QDL is not a replacement for quantum field theory, general relativity, or effective field theory. It proposes a structural constraint layer that can be tested through basis-invariance checks, scaling behavior, and closure consistency on declared model families. If empirically successful models systematically violate ledger closure under declared transforms, the closure postulate is falsified.

Intended role: a constraint layer on admissible representations — not a claim of new particles, forces, or dynamics.

Dimensional Admissibility & Measurement Integrity

A framework-independent, standards-ready audit layer for model-driven energy and infrastructure systems.

Standards-ready translation
From QDL-origin insight to national-scale model governance

This work grew out of the QDL research program but is framed independently of QDL’s broader physical claims. It extracts a general falsifiable principle—dimensional admissibility—and translates it into an audit layer for model-driven energy and infrastructure systems.

This standards framing is intentionally independent of QDL’s broader theoretical program. Its purpose is to make representational invariance testable, reportable, and auditable across real-world optimization and planning pipelines.

Latest Results

Three executed, reproducible residual-first benchmarks using public-data domains relevant to measurement and model validation.

Residual-first benchmarking treats coherent residual structure as the primary model-adequacy diagnostic under declared model families and a stated parameter budget. These records are designed for straightforward external replication. No new physical effects are claimed; the contribution is methodological.

Full benchmark summaries, replication materials, and the broader validation roadmap are on the Experiments page — and the one-click hub is on Publications → Phenomenology & Experiments.

Experimental Program

QDL is designed to be testable. The experimental validation roadmap focuses on four complementary tabletop platforms that probe QDL-driven scaling and closure claims in distinct physical regimes.

Validation roadmap
Falsifiable tests of a 3L + 2F ledger

Each platform is framed as a declared test of whether ledger-style closure adds reproducible constraints beyond conventional dimensional bookkeeping under specified transforms and parameter budgets.

  • Precision torsion-balance scaling – torque and deflection vs. arm length and mass structure.
  • NV-center frequency-shift measurements – structured offsets in spin resonance under QDL-motivated fields.
  • Cavity-mode length–frequency scaling – resonance structure vs. cavity geometry in the L–F ledger.
  • Metamaterial dispersion-collapse tests – engineered media approximating QDC-like coherence.

Why This Framework May Matter

A concise view of how the QDL program fits into contemporary theoretical and experimental physics.

QDL proposes a dimensional-closure framework intended to complement, not replace, established physical theories. Its central question is whether dimensional closure can function as a reproducible admissibility constraint on representations before dynamics or phenomenology are specified.

If this framework proves robust across relevant model classes and survives experimental and theoretical scrutiny, it could strengthen dimensional reasoning from a consistency check into a more explicit structural filter.
