Quantum criticality and the phase diagram of the cuprates
I discuss a proposed phase diagram of the cuprate superconductors as a function of temperature, carrier concentration, and a strong magnetic field perpendicular to the layers. I show how the phase diagram gives a unified interpretation of a number of recent experiments. Keynote talk, 9th International Conference on Materials and Mechanisms of Superconductivity, Tokyo, Sep 7-12, 2009.
متن کاملThe Derivation of the Fundamental Superconducting Interaction and the Phase Diagram of Cuprates
We show that an electronic phase separation (EPS) transition described by the Cahn-Hilliard theory yields regions of low free energy forming grains of low and high charge densities. These local differences in the potential energy are studied numerically and used here for the first time as the origin of an attractive interaction that gives rise to local pair formation. The resistivity transition...
متن کاملInterpretation of Inelastic Neutron Scattering Data Using the Phase Diagram of Hole-Doped Cuprates
Inelastic Neutron Scattering (INS) data in La2-xSrxCuO4 (LSCO), YBa2Cu3O6+x (YBCO) and Bi2Sr2CaCu2O8+x (Bi2212) are discussed. In the literature, the INS spectra remain far from being comprehensively understood. We show that local (Q-integrated) susceptibility data and the energy dependence of the spin susceptibility at antiferromagnetic vector, QAF = (π,π), can be interpreted by using the phas...
متن کاملHigh field phase diagram of cuprates derived from the Nernst effect.
Measurements of the Nernst signal in the vortex-liquid state of the cuprates to high fields (33 T) reveal that vorticity extends to very high fields even close to the zero-field critical temperature T(c0). In overdoped La2-xSrxCuO4, we show that the upper critical field H(c2)(T) curve does not end at T(c0), but at a much higher temperature. These results imply that T(c0) corresponds to a loss i...
متن کاملDichotomy in the T-linear resistivity in hole-doped cuprates.
From analysis of the in-plane resistivity ρ(ab)(T) of La(2-x)Sr(x)CuO(4), we show that normal state transport in overdoped cuprates can be delineated into two regimes in which the electrical resistivity varies approximately linearly with temperature. In the low-temperature limit, the T-linear resistivity extends over a very wide doping range, in marked contrast to expectations from conventional...
