Strengthened correlations near [110] edges of $d$-wave superconductors in the t-J model with the Gutzwiller approximation

Ambjorn Joki, Mikael Fogelstrom, Tomas Lofwander

We report results of a study of strongly correlated $d$-wave superconducting slabs within a t-J model solved using the statistically consistent Gutzwiller approach. For different d…
