Spin-charge separation in two-leg t-J ladders
Luhang Yang, Elbio Dagotto
Spin-charge separation is a hallmark of one-dimensional fermionic systems, yet its realization in higher dimensions remains an open question. To address this issue, we investigate…
Effects of the Next-Nearest-Neighbor Hopping on the Low-Dimensional Hubbard Model: Ferromagnetism, Antiferromagnetism, and Superconductivity
Luhang Yang, Adrian E. Feiguin, Thomas P. Devereaux +1
The Hubbard model has attracted considerable interest due to its prototypical role in describing strongly interacting electronic systems, such as high-critical-temperature supercon…
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…
