Standard behaviour of Bi2Sr2CaCu2O8+d overdoped

no code implementations • 4 Feb 2021 • G. A. Ummarino

I calculated the critical temperature and superconducting gap in the framework of one band d wave Eliashberg's theory with only one free parameter in order to reproduce the experimental data relative to Bi2Sr2CaCu2O8+d (BSCCO) in the overdoped regime.

Possible alterations of local gravitational field inside a superconductor

no code implementations • 2 Feb 2021 • G. A. Ummarino, A. Gallerati

We calculate the possible interaction between a superconductor and the static Earth's gravitational fields, making use of the gravito-Maxwell formalism combined with the time-dependent Ginzburg-Landau theory.
