Author(s): Daniel J. Long, Edmund Tarleton, Alan C. F. Cocks, and Felix Hofmann We investigate the mechanisms involved in the thermomigration of interstitial hydrogen in metals. Using irreversible thermodynamics, we develop a comprehensive mechanistic model to capture the controlling effects. Crucially, through validation against published experimental data, our results demonst… [Phys. Rev. Lett. 137, 096301] Published Mon Aug 24, 2026
