Optimal inhomogeneity for pairing in Hubbard systems with next-nearest-neighbor hopping
Gideon Wachtel, Shirit Baruch, Dror Orgad
Previous studies have shown that bipartite Hubbard systems with inhomogeneous hopping amplitudes can exhibit higher pair-binding energies than the uniform model. Here we examine wh…

Spectral signatures of modulated d-wave superconducting phases
Shirit Baruch, Dror Orgad
We calculate within a mean-field theory the spectral signatures of various striped d-wave superconducting phases. We consider both in-phase and anti-phase modulations of the superc…
