Simple theory of extremely overdoped HTS
نویسنده
چکیده
We demonstrate the existence of a simple physical picture of superconductivity for extremely overdoped CuO2 planes. It possesses all characteristic features of HTS, such as a high superconducting transition temperature, the dx2−y2 symmetry of order parameter, and the coexistence of a single electron Fermi surface and a pseudogap in the normal state. Values of pseudogap are calculated for different doping levels. An orbital paramagnetism of preformed pairs is predicted. PACS numbers: 74.20.-z; 74.78.-w

Search for ferromagnetic order in overdoped copper-oxide superconductors
In copper-oxides that show high-temperature superconductivity (HTS), the critical temperature (Tc) has a dome-shaped doping dependence. The cause of demise of both Tc and superfluid density ns on the overdoped side is a major puzzle. A recent study of transport and diamagnetism in a large number of overdoped La2-xSrxCuO4 (LSCO) films shows that this cannot be accounted for by disorder within th...
متن کاملOptimization of an HTS Induction/Synchronous Motor According to Changing of HTS Tapes Critical Current by Analytical Hierarchy Process
This paper represents the performance of a squirrel-cage High Temperature Superconducting Induction/ Synchronous Motor (HTS-ISM) based on nonlinear electrical equivalent circuit. The structure of the HTS-ISM is the same as that of the squirrel-cage type induction machine, and the secondary windings are fabricated by the use of the HTS wires. It has already been shown that based on the experimen...
متن کاملHeat transport in a strongly overdoped cuprate: Fermi liquid and a pure d-wave BCS superconductor.
The transport of heat and charge in the overdoped cuprate superconductor Tl(2)Ba2CuO(6+delta) was measured down to low temperature. In the normal state, obtained by applying a magnetic field greater than the upper critical field, the Wiedemann-Franz law is verified to hold perfectly. In the superconducting state, a large residual linear term is observed in the thermal conductivity, in quantitat...
متن کاملBand structure and fermi surface of an extremely overdoped iron-based superconductor KFe2As2.
We have performed high-resolution angle-resolved photoemission spectroscopy on heavily overdoped KFe_{2}As_{2} (transition temperature T_{c} = 3 K). We observed several renormalized bands near the Fermi level with a renormalization factor of 2-4. While the Fermi surface around the Brillouin-zone center is qualitatively similar to that of optimally doped Ba_{1-x}K_{x}Fe_{2}As_{2} (x = 0.4; T_{c}...
متن کاملCoherent versus incoherent transport in layered doped Mott insulators.
There exist strong experimental evidences for the dimensional cross-over from two to three dimensions as La2−xSrxCuO4 compounds are overdoped. In this paper we describe the dimensional cross-over of the layered correlated metal in the gauge theory framework. In particular, we obtain the anomalous exponent 3/2 for the temperature dependence of resistivity observed in overdoped La2−xSrxCuO4 . PAC...
