Solid-State Magnonic Heat Recuperator Based on Altermagnetic Tunnel Junctions

This upload contains the complete Research Artifact Bundle for the "Solid-State Magnonic Heat Recuperator Based on Altermagnetic Tunnel Junctions" (informally known as the Zimnitsky Cell). The project introduces a paradigm shift in waste heat recovery (150°C - 300°C), bypassing the phonon-shunting bottleneck of classical thermoelectric generators (TEGs) by transitioning to localized femtosecond magnon-phonon kinetics in altermagnetic thin films. The system uncouples heat conduction from electrical generation by operating on a purely isothermal equilibrium plateau (∇ T = 0 across the lattice) combined with an internal vertical bi-gradient optical-magnon pump, enabling a steady-state active power output of ~66W (20V / 3.3A) for a standard 40×40×4 mm Peltier-compatible footprint. *** ### 📦 Included Files & Repository Structure:1. **Solid-State Magnonic Heat Recuperator.pdf** — The complete academic preprint text in standard double-column format compiled via LaTeX (including Introduction, Mathematical Framework, and Figure Descriptions).2. **Cell.zip** — Complete Open Source cross-platform C# (.NET 8.0) numerical solver implementing a conservative 1D finite-difference time-domain (FDTD) scheme with harmonic thermal conductivity averaging at heterogeneous thin-film boundaries.3. **simulation_data.csv** — The raw multi-physics dataset containing 500,000 transient time-steps utilized to verify the thermodynamic log-acceleration and power stabilization.4. **Visualizers & CAD Schematics (.zip/.png/.svg)** — Python-driven and vector visualization suites mapping the macro-scale microchannel layouts, Z-cascade commutation "snake" networks, and deep nanoscale vertical thermal gradient profiles within the 2.2 nm RuO₂ altermagnetic barrier layer. *** ### ✉️ Correspondence:For technical inquiries, source code collaborations, or venture investment proposals, please contact the author directly at: [email protected]
