We study the temperature-dependent electronic B_{1g} Raman response of a slightly underdoped single crystal HgBa_{2}Ca_{2}Cu_{3}O_{8+δ} with a superconducting critical temperature T_{c}=122  K. Our main finding is that the superconducting pair-breaking peak is associated with a dip on its higher-energy side, disappearing together at T_{c}. This result reveals a key aspect of the unconventional pairing mechanism: spectral weight lost in the dip is transferred to the pair-breaking peak at lower…

Intimate link between charge density wave, pseudogap and superconducting energy scales in cuprates
The cuprate high-temperature superconductors develop spontaneous charge density wave (CDW) order below a temperature TCDW and over a wide range of hole doping (p). An outstanding challenge in the

It has become clear that the anomalous properties of cuprate superconductors are intimately related to the formation of a pseudogap. Within the framework of the kinetic-energy-driven superconducting

We discuss the characteristic features of triple Cu-O2 layer cuprates superconductors, by comparing those of single and double layer cuprates superconductors. After a brief introduction to multilayer
Crystal growth and doping control of HgBa2CuO4+δ, the model compound for high-T superconductors
A new method to grow very high quality single crystals of the superconducting HgBa2CuO4+{\delta} mercury cuprates is reported. The single crystals are platelet-shaped, with surfaces of high optical
