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 elastic band algorithm, where here the glo...
The performance of an analytical expression for algorithmic decoherence time is investigated for non-Born-Oppenheimer molecular dynamics. There are two terms in the function that represents the dependence of the decoherence time on the system parameters; one represents decoherence due to the quantum time-energy uncertainty principle and the other represents a back reaction from the decoherent f...

Based on the identification of 38 white dwarfs with halo kinematics, in a survey covering 10% of the sky near the south galactic pole, Oppenheimer et al. (1) argued that at least 2% of the dark matter in the Milky Way galaxy has now been detected directly. Put into context, the Oppenheimer et al. result implies that the stellar remnant mass of the halo may be comparable to that of the entire di...
