Whether the polaron is large polaron or small polaron is judged from the size of the localization of the electron wavefunction. T. Holstein had studied the diffusion behavior of small polaron in detail in 1959: (1)Annals of Physics (New York) 8 (1959), 325. (2)Annals of Physics (New York) 8 (1959), 725. The physics of the phonon assisted atomic diffusion in solid is the same as the physics of small polaron diffusion. C. P. Flynn and A. M. Stoneham in 1970 and D. Emin, M. I. Baskes and W. D. Wilson had applied the small-polaronic theory to light interstitials in metals: (1)C. P. Flynn, and A. M. Stoneham, Phys. Rev. B 1, 3966 (1970). (2)D. Emin, M. I. Baskes and W. D. Wilson, Phys. Rev. Lett. 42, 791 (1979). Afterwards, P. G. Sundell et al. studied a lot on the diffusion of hydrogen in solids and surfaces: (1)P. G. Sundell and G. Wahnstron, Phys. Rev. Lett. 92, 155901 (2004). (2)P. G. Sundell and G. Wahnstron, Phys. Rev. B 70, R081403 (2004). (3)P. G. Sundell and G. Wahnstron, Phys. Rev. B 70, 224301 (2004). (4)B. Bhatia and D. S. Sholl, Phys. Rev. B 72, 224302 (2005). (5)P. G. Sundell et al., Phys. Rev. B 76, 094301 (2007). There are a lot of information within these papers and the references therein. （二）non-collinear spin polarization in DFT calculations Excellent reference papers: (1) U. von Barth and L. Hedin, J. Phys. C: Solid State Phys., Vol. 5, p1629 (1972) "A local exchange-correlation potential for the spin polarized case: I" (2) U. von Barth, Phys. Rev. A, vol. 20, p 1693 (1979) "Local-density theory of multiplet structure" (3) J. Kubler et al., J. Phys. F: Met. Phys. vol. 18, p 469-483 (1988) "Density functional theory of non-collinear magnetism" (4) M. C. van Hemert et al., Phys. Rev. Lett., vol. 51, p 1167 (1983) "Ab Initio calculation of the heisenberg exchange interaction between O2 molecular" (5) L. Nordstrom, D. J. Singh, Phys. Rev. Lett. vol. 76, p 4420 (1996) "Noncollinear Intra-atomic magnetism" (6) T. Oda, et al., Phys. Rev. Lett. vol. 80, p 3622 (1998) "Fully Unconstrained Approach to Noncollinear Magnetism: Application to Small Fe Clusters" (7) R. Gebauer et al., Phys. Rev. B vol. 61, p 6145 (2000) "Noncollinear spin polarization from frustrated antiferromagnetism: A possible scenario for molecular oxygen at high pressure" (8) D. Hobbs et al., Phys. Rev. B vol. 62, p 11556 (2000) "Fully unconstrained noncollinear magnetism within the projector augmented-wave method" （三）simulating chemical reactions by DFT (1) Searching the reaction pathways and transition states Nudged elastic band method could be used.
