Effect of electronic excitations on hydrogen behavior in tungsten

The interaction between ions should be greatly modified under electronic excitation states, subsequently altering the interactions between materials.We perform a series of first-principles calculations to predict the solution and diffusion behaviors of interstitial hydrogen (H) in tungsten (W) under various electronic excitations.Qualitatively, the
