Finding transition states for crystalline solid–solid phase transformations [PDF]
Proceedings of the National Academy of Sciences, 2005 We present a method to identify transition states and minimum energy paths for martensitic solid–solid phase transformations, thereby allowing quantification of the activation energies of such transformations. Our approach is a generalization of a previous method for identifying transition states for chemical reactions, namely the climbing image-nudged
