【 摘 要 】

We have used optical-pump far-infrared probe spectroscopy to probe the law energy electron dynamics of high temperature superconductors and colossal magnetore-sistance magnanites. For the superconductors Yba2Cu3O7, picosecond conductivity measurements probe the interplay between Cooper-pairs and quasiparticles.
