Superconductor Discovery
InvDesFlow-AL is applied to discover high-temperature superconductors, enabling exploration in unbounded chemical space. It uses a multi-stage active learning strategy with sequential model refinement and committee-based validation, identifying materials with targeted properties under ambient pressure.
Breakthrough Superconductor: Li2AuH6 (140 K)
InvDesFlow-AL successfully identified Li2AuH6 as a conventional BCS superconductor with an ultra-high transition temperature of 140 K under ambient pressure. This discovery marks the highest Tc achieved by conventional superconductors to date, significantly surpassing the McMillan limit (40 K) and the liquid nitrogen temperature threshold (77 K). Its dynamic stability and robust electron-phonon interactions underscore its potential for practical applications, having also identified several other promising superconducting materials.
Crystal Structure Prediction Accuracy
For crystal structure prediction (CSP) tasks, InvDesFlow-AL achieves state-of-the-art accuracy. By leveraging diversity sampling and active learning-based query-by-committee, it reduces the root mean square error (RMSE) of atomic positions, outperforming existing generative models and traditional methods.
| Method | RMSE (MP-20) | Match Rate (%) (MP-20) |
|---|---|---|
| DiffCSP [16] | 0.0631 | 51.49 |
| CrystaLLM [11] | 0.0437 | 55.85 |
| EquiCSP [40] | 0.0510 | 57.39 |
| InvDesFlow-AL | 0.0423 | 60.83 |
InvDesFlow-AL significantly outperforms previous methods in both RMSE and Match Rate, indicating superior accuracy and robustness in crystal structure prediction.
UHTC Generation
The framework's generalization capability extends to ultra-high-temperature ceramics (UHTCs), critical for aerospace and energy engineering. By fine-tuning on limited UHTC data, InvDesFlow-AL can generate novel, high-stability ceramic structures like TaB2, ZrC, and HfN, which have been experimentally validated for their exceptional properties.
