Ultrafast Collective Dynamics in the Charge-Density-Wave Conductor K${}_{0.3}$MoO${}_3$

Yuhang Ren, Zhu'an Xu, Gunter L\U{fc}pke

Low-energy coherent charge-density wave excitations are investigated in blue bronze (K${}_{0.3}$MoO${}_3$) and red bronze (K${}_{0.33}$MoO${}_3$) by femtosecond pump-probe spectroscopy…
