Abstract: The motion of atoms on interatomic potential energy surfaces isfundamental to the dynamics of liquids and solids. An accelerator-basedsource of femtosecond x-ray pulses allowed us to follow directly atomicdisplacements on an optically modified energy landscape, leadingeventually to the transition from crystalline solid to disorderedliquid. We show that, to first order in time, the dynamics are inertial,and we place constraints on the shape and curvature of thetransition-state potential energy surface. Our measurements point towardanalogies between this nonequilibrium phase transition and theshort-time dynamics intrinsic to equilibrium liquids. [ABSTRACT FROM AUTHOR]
