ROOM-TEMPERATURE SUPERCONDUCTIVITY / RESEARCH WORKBENCH
Our working hypothesis: an ordered hydrogen-bearing solid, stabilized by a light-element framework. Explore pairing requirements, prepare calculations, and test what could disprove it.
Explore a two-mode spectrum or analyze your own electron–phonon spectrum.
ALLEN–DYNES ESTIMATE
Scale all spectral weights together; keep mode energies fixed.
| Scenario | λ | ωlog | μ* | Model Tc | Origin |
|---|
Up to eight scenarios, saved in this browser. These are model comparisons, not a ranking of real materials.
A documented hydride benchmark helps validate the tools before testing the framework hypothesis.
Drag or use arrow keys to rotate. Cell edges show periodicity; no chemical bonds are inferred.
Xu et al. predict about 130 K for ordered MgAlFeH₆. Its published lattice and sites supply a starting cell. This workbench reconstructs rounded coordinates; it has not reproduced their calculation. Primary paper ↗
The original framework drawing has no assigned crystal structure. SrNH₄B₆C₆ is relevant, but its authoritative structural file is not bundled. Import that geometry before assigning energies or Tc to it. Explore the hypothesis ↗

The browser explores pairing. Quantum ESPRESSO, EPW and SSCHA run on a configured workstation or cluster.
RUNNABLE PYTHON TOOLKIT
Includes structures, variants, checksummed job preparation, staged QE execution, spectral integration, a numerical isotropic Eliashberg solver, and competing-phase enthalpy comparisons.

Progress is evidence for a reproducible phase, not a single resistance anomaly.

PRESSURE-RELEASE HYPOTHESIS
Explore a single-event Arrhenius model. The barrier must come from a pathway calculation or experiment.
τ = ν⁻¹ exp(Eb / kBT). This is not a bulk lifetime prediction: nucleation sites, diffusion and changing decomposition pathways are omitted. Short molecular dynamics cannot establish long-term retention.
Sources checked 9 September 2026. No room-temperature, ambient-pressure material is demonstrated by this project.
The bet is to preserve useful hydrogen-related electron–phonon coupling while a framework stabilizes the structure after pressure release. Ordering, carrier tuning and retention are hypotheses to test. No winning composition has been identified.
Original annotated concept ↗Sun & Zhu predict about 85 K for SrNH₄B₆C₆ and up to 115 K for PbNH₄B₆C₆ at ambient pressure. These motivate the route, but do not establish 293 K superconductivity. High-frequency hydrogen motion alone does not guarantee strong pairing.
Communications Physics, 2024 ↗Xu et al. predict roughly 130 K for ordered MgAlFeH₆. Their random-alloy estimate is around 40 K. The ordered phase is metastable, with a reported energy above hull near 0.11 eV/atom. These are literature results, not workbench outputs.
npj Computational Materials, 2026 ↗| Quantity | Calculation | Limit |
|---|---|---|
| λ, ωlog, ω₂ | Einstein-mode moments or trapezoidal integration of α²F. | No link from atomic coordinates to the spectrum is assumed. |
| Browser Tc | Allen–Dynes interpolation, including f₁ and f₂. | No anisotropy, explicit anharmonicity or phase-coherence calculation. |
| Python Tc | Linearized isotropic Matsubara equation; largest pairing eigenvalue reaches one. | Finite frequency grid; symmetric Coulomb cutoff. Convergence and a valid spectrum are required. |
| Phase energy | Balanced mixture of supplied reference enthalpies. | Not a global convex hull or decomposition rate. |
| Retention | One-event Arrhenius waiting time. | Not a macroscopic sample lifetime. |
λ = 2 ∫ α²F(E) / E dE ln(Elog / 1 meV) = (2/λ) ∫ α²F(E) / E ln(E / 1 meV) dE E₂² = (2/λ) ∫ α²F(E) E dE Tc = f₁ f₂ Elog / (1.2 kB) × exp[−1.04(1+λ)/(λ−μ*(1+0.62λ))] f₁ = [1 + (λ / (2.46(1+3.8μ*)))^(3/2)]^(1/3) f₂ = 1 + (E₂/Elog−1)λ² / [λ² + (1.82(1+6.3μ*)E₂/Elog)²] kB = 0.08617333262145 meV/K
The μ* range is a sensitivity interval, not a confidence interval. Ideal isotope scaling changes H-mode energies by 1/√2 and holds λ fixed; real isotope effects can alter structure and anharmonicity.
