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…

Particle-hole asymmetric ferromagnetism and spin textures in the triangular Hubbard-Hofstadter model
Jixun K. Ding, Luhang Yang, Wen O. Wang +8
In a lattice model subject to a perpendicular magnetic field, when the lattice constant is comparable to the magnetic length, one enters the "Hofstadter regime," where continuum La…
