Vorticity, phase stiffness and the cuprate phase diagram
The vortex-Nernst effect is a highly sensitive probe for detecting vortex motion in a type II superconductor [1]. In the past 3 years, we have used it to map out the region in the fieldtemperature (H-T ) plane in which vorticity may be observed [2,3,4,5]. The results provide a fresh perspective on the cuprate phase diagram which we sketch here. When a superconductor (in the vortex-liquid state)...
متن کاملPerspective on the phase diagram of cuprate high-temperature superconductors
Universal scaling laws can guide the understanding of new phenomena, and for cuprate high-temperature superconductivity the influential Uemura relation showed, early on, that the maximum critical temperature of superconductivity correlates with the density of the superfluid measured at low temperatures. Here we show that the charge content of the bonding orbitals of copper and oxygen in the ubi...
متن کاملToward a unified magnetic phase diagram of the cuprate superconductors.
We propose a unified magnetic phase diagram of cuprate superconductors. A new feature of this phase diagram is a broad intermediate doping region of quantumcritical, z = 1, behavior, characterized by temperature independent T1T/T2G and linear T1T , where the spin waves are not completely absorbed by the electron-hole continuum. The spin gap in the moderately doped materials is related to the su...
متن کاملPhase diagram of underdoped cuprate superconductors: Effects of Cooper-pair phase fluctuations
In underdoped cuprates fluctuations of the phase of the superconducting order parameter play a role due to the small superfluid density. We consider the effects of phase fluctuations assuming the exchange of spin fluctuations to be the predominant pairing interaction. Spin fluctuations are treated in the fluctuation-exchange approximation, while phase fluctuations are included by Berezinskii-Ko...
متن کاملUniversal sheet resistance and revised phase diagram of the cuprate high-temperature superconductors.
Upon introducing charge carriers into the copper-oxygen sheets of the enigmatic lamellar cuprates, the ground state evolves from an insulator to a superconductor and eventually to a seemingly conventional metal (a Fermi liquid). Much has remained elusive about the nature of this evolution and about the peculiar metallic state at intermediate hole-carrier concentrations (p). The planar resistivi...
