Band-dependent Quasiparticle Dynamics in Single Crystals of the Ba[subscript 0.6]K[subscript 0.4]Fe[subscript 2]As[subscript 2] Superconductor Revealed by Pump-Probe Spectroscopy
We report on band-dependent quasiparticle dynamics in Ba[subscript 0.6]K[subscript 0.4]Fe[subscript 2]As[subscript 2](Tc=37 K) measured using ultrafast pump-probe spectroscopy. In the superconducting state, we observe two distinct relaxation processes: a fast component whose decay rate increases li...
