Strengthened correlations near [110] edges of -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 -wave superconducting slabs within a t-J model solved using the statistically consistent Gutzwiller approach. For different d…

Impurity strength-temperature phase diagram with phase crystals and competing time-reversal symmetry breaking states in nodal -wave superconductors
Kevin Marc Seja, Niclas Wall-Wennerdal, Tomas Löfwander +3
Phase crystals are a class of nonuniform superconducting ground states characterized by spontaneous phase gradients of the superconducting order parameter. These phase gradients no…
