FeLi₂B₂H₃ Room-Temperature Superconductor Revisited- Alpha and Beta Phases-. pdf

Title: Hexagonal Necessity: The Bi-Phase Resonance Path to Room-Temperature Superconductivity in FeLi₂B₂H₃ This paper presents a theoretical framework and synthesis roadmap for Room-Temperature Superconductivity (RTSC) in the quaternary hydride FeLi₂B₂H₃. Utilizing the Informational Constraints Quantum Event Realism (ICQER-ToE) framework, we resolve the "reproducibility crisis" in hydride research by defining two distinct structural phases. Phase 1 (Beta): An ambient-stable structural template (P=0 GPa, c 4. 20 Å) where Hydrogen atoms are securely locked in 3f interstitial sites. This phase serves as the mandatory chemical foundation for structural verification via XRD. Phase 2 (Alpha): An active superconducting state triggered by a controlled vertical compression to a 5 GPa pressure ceiling. This contraction (c 3. 25 Å) tunes the internal B-H lattice to a 32. 2 THz Optical Resonance, acting as a quantum shield against thermal noise to stabilize superconductivity at 298 K. We provide comprehensive lattice parameters, phonon profiles, and critical metrics (Tc 298--315 K, Jc 10⁷ A/cm²) for experimental validation.
