Phys. Rev. Lett. 102, 066404 (2009) [4 pages]Dynamics of Photoinduced Charge-Density-Wave to Metal Phase Transition in K0.3MoO3Received 21 October 2008; published 13 February 2009 We present the first systematic studies of the photoinduced phase transition from the ground charge density wave (CDW) state to the normal metallic state in the prototype quasi-1D CDW system K0.3MoO3. Ultrafast nonthermal CDW melting is achieved at the absorbed energy density that corresponds to the electronic energy difference between the metallic and CDW states. The results imply that on the subpicosecond time scale when melting and subsequent initial recovery of the electronic order takes place the lattice remains unperturbed. © 2009 The American Physical Society URL:
