| Outline of Final Research Achievements |
Photoinduced phase transition dynamics in the superconducting and pseudogap states of Bi-based high-Tc superconductors have been investigated using ultrashort pulses and the following conclusions are obtained: 1) existence of a spontaneous symmetry breaking in the psuedogap state, 2) distinct relationship between phase coherence and gap formation, 3) absence of long-range electronic ordering and carrier lorcalization in the pseudogap formation, 4) enhanced contribution of the pseudogap to the gap formation in the underdoped sample.
