Metastable Quantum Cavitation Technical Supplement No. 1

Metastable Quantum Cavitation — Technical Supplement No. 1 This technical supplement accompanies the original publication Metastable Quantum Cavitation as a Continuous Bidirectional Transport Framework (L. Benedettini, A.M. Sabatini, 2026; DOI: https://doi.org/10.5281/zenodo.22944164). It extends the original theoretical framework through explicitly specified and reproducible numerical investigations of continuous bidirectional quantum transport in a three-part B–I–C architecture. The study introduces a fully defined Hamiltonian, phase-dependent modulation, matched META/NO-META controls, open-system Lindblad dynamics, and dissipative load models with explicit energy accounting. The computational investigation includes 76 open-system simulations, 38 matched comparisons, and six closed-system trajectories, supported by numerical convergence tests, analytical benchmarks, and sensitivity analyses. Results demonstrate phase-dependent transport behavior, bidirectional current activity, and genuine load back-action. The energetic response depends on the chosen parameters and load model; no universal enhancement or independent energy source is established. The numerical implementations presented here differ from the exploratory calculations in the original publication. Consequently, they neither confirm nor refute the previously reported approximately +0.8% load enhancement under its original protocol. A separate semiclassical discussion retains the illustrative weak-field gravitational scaling as a theoretical hypothesis, without claiming an experimentally demonstrated spacetime effect. Reproducibility: The accompanying BIC_reproducibility_package.zip provides Python source code, simulation parameters, numerical datasets, validation tests, and integrity hashes, enabling independent inspection and reproduction of the reported computational results. This publication is intended as an independent technical and computational supplement to the original framework, not as a replacement or revised version of the primary paper.
