Evidence for polarons and itinerant carriers in superconductivity from time-resolved optical measurements on YBa2Cu3O7-Delta

Time-resolved optical relaxation measurements on time scales from 10(-13) to 10(-8) s as a function of energy (0.8-3 eV) and temperature give evidence for the existence of two different carrier relaxation processes, indicating the presence of two distinct electronic subsystems in the normal state in...
