dc.descriptionStructural transformations, electronic spectra and ballistic transport in pulled gold nanowires are investigated with ab initio simulations, and correlated with recent measurements. Strain-induced yield of an initial double-strand wire results first in formation of a bent-chain which transforms upon further elongation to a linear atomic chain exhibiting dimerized atomic configurations. These structures are stabilized by directional local bonding with spd-hybridization. The conductance of the initial double-stranded contact is close to 2g_0 and it drops sharply to 1g_0 during the transformation to a single chain, exhibiting subsequently a 1g_0 plateau extending over an elongation well above typical Au-Au distances.
