Order by projection in single-band Hubbard model: a DMRG study
Shuyi Li, Cheng Peng, Yue Yu +2
In a Fermi system near or at half-filling, a specific superconducting pairing channel, if not explicitly included in the Hamiltonian, can be boosted by suppressing a competing pair…

The emergence of antiferromagnetic correlations and Kondo-like features in a two-band model for infinite-layer nickelates
Fangze Liu, Cheng Peng, Edwin W. Huang +3
We report a determinant quantum Monte Carlo study of a two-band model, inspired by infinite-layer nickelates, focusing on the influence of interlayer hybridization between $3d_{x^2…

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…
