    We have investigated twin boundaries in double-lattice hexagonal close-packed metallic materials, focusing on their atomic
    geometry. Combining accurate ab-initio methods and large-scale atomistic simulations we address the following two fundamental
    questions: (i) What are the possible intrinsic twin boundary structures in hcp crystals? (ii) Are these structures stable against small
    distortions? In order to help end a decade-long controversy over the experimental observations of the atomic structures of twin
    boundaries, we have determined the energetics, spectra, and transition mechanisms of the twin boundaries. Our results confirm
    that the mechanical stability controls structures which are observed
