Electrostatic Potential in High-Temperature Superconducting Cuprates : Extended Ginzburg-Landau Theory

الملخص EN

The electrostatic potential and the associated charge distribution in the vortices of high-Tc superconductors involving mixed symmetry state of the order parameters have been studied.

The work is carried out in the framework of an extended Ginzburg-Landau (GL) theory involving the Gorter-Casimir two-fluid model and Bardeen's extension of GL theory applied to the high-Tc superconductors.

The properties are calculated using the material parameters relevant for the high-Tc cuprate YBCO.
