Chiral d+is superconducting state in the two dimensional t-t' Hubbard model
J. Mraz, R. Hlubina
Applying the recently developed variational approach to Kohn-Luttinger superconductivity to the t-t' Hubbard model in two dimensions, we have found, for sizeable next-nearest neigh…

Josephson effect as a measure of quantum fluctuations in the cuprates
R. Hlubina, M. Grajcar, J. Mraz
Quantitative analysis of the Josephson effect is shown to provide direct information about phase fluctuations in the superconducting banks. Applying the analysis to the cuprates, s…

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…
