Recovery of a Luther-Emery phase in the three-band Hubbard model with longer-range hopping
Luhang Yang, Thomas P. Devereaux, Hong-Chen Jiang
A lightly doped single-band Hubbard model on a two leg ladder exhibits a Luther-Emery phase, while the three-band Hubbard ladder behaves as a Luttinger liquid upon hole doping. In…

Pair density wave and superconductivity in a kinetically frustrated doped Emery model on a square lattice
Hong-Chen Jiang, Thomas Peter Devereaux
The quest to understand the nature of superconductivity in cuprates has spotlighted the pair density wave (PDW) -- a superconducting state characterized by a spatially modulated or…
