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…
A contractor-renormalization study of Hubbard plaquette clusters
Shirit Baruch, Dror Orgad
We implement the contractor-renormalization method to study the checkerboard Hubbard model on various finite-size clusters as function of the inter-plaquette hopping t' and the on-…
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…
Weak-coupling phase diagrams of bond-aligned and diagonal doped Hubbard ladders
Shirit Baruch, Dror Orgad
We study, using a perturbative renormalization group technique, the phase diagrams of bond-aligned and diagonal Hubbard ladders defined as sections of a square lattice with nearest…
