Kohn-Luttinger instability of the t-t' Hubbard model in two dimensions: variational approach
J. Mraz, R. Hlubina
An effective Hamiltonian for the Kohn-Luttinger superconductor is constructed and solved in the BCS approximation. The method is applied to the t-t' Hubbard model in two dimensions…

What does the Josephson effect tell us about the superconducting state of the cuprates?
R. Hlubina, M. Grajcar, E. Il'ichev
We review the recent measurements of the current-phase relation in cuprate Josephson junctions. Special attention is paid to 45 degree grain boundary junctions and to c-axis juncti…

Josephson effect in the cuprates: microscopic implications
R. Hlubina
In the tunnel limit, the current-phase relation of Josephson junctions can be expanded as . Standard BCS theory predicts that and $I_2/I_1…
