Abstract

High T c cuprates are characterized by three characteristic energy scales: T c , T* c , and T*. The lowest scale, T c , corresponds to the usual transition to the dissipationless state (R=0) with a macroscopic phase coherence. The higher energy scale, T* c , describes the diamagnetic transition. The region T* c >T>T c is characterized by the presence of superconducting regions embedded in a normal metallic matrix. The highest energy scale (T*) corresponds to the formation of the structure, phase separation, and to the opening of the CDW gap.
