Lübcke, Andre Demsar, Jure Using femtosecond time-resolved x-ray diffraction, we directly monitor the coherent lattice dynamics through an ultrafast charge-density-wave-to-metal transition in the prototypical Peierls system K<sub>0.3</sub>MoO<sub>3</sub> over a wide range of relevant excitation fluences. While in the low fluence regime we directly follow the structural dynamics associated with the collective amplitude mode; for fluences above the melting threshold of the electronic density modulation we observe a transient recovery of the periodic lattice distortion. We can describe these structural dynamics as a motion along the coordinate of the Peierls distortion triggered by the prompt collapse of electronic order after photoexcitation. The results indicate that the dynamics of a structural symmetry-breaking transition are determined by a high-symmetry excited state potential energy surface distinct from that of the initial low-temperature state. 2015-02-04T09:12:21Z Huber, Lucas Ferrer, Andres Laulhé, Claire Huber, Tim Beaud, Paul Schäfer, Hanjo Dornes, Christian Kubacka, Teresa Dornes, Christian Lübcke, Andre Beaud, Paul Ravy, Sylvain
